Illumina Vitamin C Perfecting Treatment Intensif


This Vitamin C plus exfoliating serum offers revitalized cellular renewal. It decongests acne-prone skins and smooths wrinkles and discoloration for mature skins.

Illumina has eliminated every single bit of congestion in my skin and it is now perfectly smooth, something I have never consistently experienced with my skin before. It is so radiant and luminous, something I saw within 3 days of using it but has only become better as time has gone on. After more than a decade of struggling with my skin and waiting for it to just be smooth and pretty and glow-y, I finally have the skin of my dreams!

About Illumina


Illumina is a Vitamin C and exfoliating serum in one. It uses botanical extracts and exceptionally gentle pumpkin enzyme instead of harsh acids or retinoids to balance cellular turnover and revive the skin’s natural glow and smooth texture.

It also contains Sodium Ascorbyl Phosphate (a stable form of Vitamin C) to brighten and firm. Studies have shown this type of Vitamin C may help decrease the appearance of acne lesions.

We recommend starting by using Il every other evening, then adjusting if needed. Illumina is to be used 1x per week – 1x per day in the evening.

Apply after cleansing/toning and before moisturizer/oils.

If using Illumina, do not apply any other exfoliating product at the same time.

Featured Botanicals

Pumpkin Enzymes – AHAs or traditional enzymes such as papain or bromelain tend to be irritating on the skin. Unlike traditional materials, pumpkin enzymes show an uncommonly mild irritation profile in tests; results confirm that pumpkin is only slightly more irritating than glycerin.
White Willow Bark – White willow bark extract acts as an anti-inflammatory and analgesic agent. Willow bark extracts are employed as a natural source of salicylic acid. White Willow Bark provides the benefits of salicylic acid such as BHA exfoliation, and anti-microbial action, without any of the typically associated irritation.
Vigna Acontifolia Seed – Vigna Acontifolia Seed Extract has a demonstrated ability to help boost cell renewal, similar to retinol, without the associated irritation. When used at similar levels, the extract’s efficacy comparable to that of Retinol. Additionally, it has potent antioxidant properties.
Sodium Ascorbyl Phosphate – Several studies have shown this form of Vitamin C to be as effective as retinol in reducing acne lesions. In one study, acne lesions decreased by 20% after 4 weeks, and 48% after 8 weeks using SAP and 21% and 49% using retinol. 
Burdock Root – An exceptional multi-tasking botanical. Cools heat, strengthens the lymphatic processes, purifies and removes toxins. Soothing and anti-bacterial properties. One study showed that topical treatment with a natural burdock extract significantly improved the metabolism of the dermal extracellular matrix and led to a visible wrinkle reduction.
Plant Ceramides – A crucial component of a healthy skin barrier. The lipid matrix of a healthy, protective skin barrier consists of fatty acids (found in oils and butters), ceramides and cholesterol (much more difficult to find as topical supplements). Our ceramides are plant derived and support the health of the stratum corneum.
King of Bitters – is traditionally used in Ayurveda and Chinese Medicine. Highly anti-inflammatory, with some anti-bacterial activity. Has been shown to decrease glycation caused by UV radiation, as well as increase skin collagen content.
Smallflower + Saw Palmetto CO2 Complex – both of these herbs show significant activity against the 5alpha reductase enzyme that increases testosterone activity in the skin, leading to a higher instance of acne lesions. Since beta sisterols (the active component of Saw Palmetto) are oil soluble, we use a rare CO2 extraction to fully draw out the powers of the phytonutrients.
Olive Leaf – is traditionally used in Ayurveda and Chinese Medicine. Strongly anti-bacterial, anti-inflammatory and antioxidant.

7 serums in 1

Non-irritating exfoliation complex

Non-irritating exfoliation complex

A proprietary complex consisting of three powerful botanicals including pumpkin enzyme, moth bean plant (also know as Nature’s retinol) and white willow bark and a next generation alpha-hydroxy acid. This complex works to normalize skin cell turnover, boost collagen production and excavate clogged pores.

Anti-inflammatory complex

Anti-inflammatory complex

At the root of acne is inflammation. We’ve sourced supplement-quality extracts of green tea, magnolia bark and skullcap root that provide concentrated amounts of the anti-inflammatory flavonoids baicalin, EGCG and the lignan honokiol. These natural chemicals are some of the most powerful anti-inflammatories available.

Antioxidant Complex

Antioxidant Complex

Oxidation is the leading cause of pre-mature aging. It also contributes to acne because when sebum oxidizes, it becomes comedogenic and thick. Our antioxidant complex comprises a whopping 16% of this formula and includes stable vitamin C and green tea polyphenols.

Pore Cleansing Complex

Pore Cleansing Complex

Acne can be thought of as a pearl of sebum and bacteria growing around a “seed” of dead skin clumped with hardened sebum. Salicylic acid naturally found in willow bark scours the inside of pores to keep them clear, while skin-identical ceramides minimize the incidence of impactions by keeping the skin hydrated and elastic.

Wound Healing Complex

Wound Healing Complex

Sterols (a type of lipid) derived from pomegranate help soothe inflamed, irritated and dry skin. Powerful anti-inflammatory extracts and Vitamin C help skin to heal blemishes faster and with less scarring. We use a preservative that is extremely gentle and good for even very sensitive skin.

Anti-aging Complex

Anti-aging Complex

Moth Bean extract has been shown to stimulate collagen to the same degree as retinol. Antioxidants repair existing damage while blocking future damage. Vitamin C speeds healing and brightens skin. Ceramides repair the skin barrier, visibly improving elasticity and the skin’s ability to shield itself from environmental stress.

Hydration Complex

Hydration Complex

Acneic skin is often damaged and needs supportive, healing ingredients, nothing harsh and drying. In fact, oily and acne-prone skin can often indicate that skin is severely lacking in hydration. Our skin barrier often needs supplementation with ceramides and sterols to properly retain moisture and elasticity. Properly hydrating skin brings a noticeable decrease in acne.

Recommended Application Method:


Pump 1-2 pumps of product onto fingertips. Gently dot finger tips onto left cheek, right cheek, chin and forehead, making sure that the first area you dot doesn’t take all the product. Once product has been evenly divided between the 4 quadrants of the face, use both hands to massage product into the skin, working to cover the entire facial area. If there is not enough product, use 1/2 more pump where needed. If there is too much product, spread it onto neck as best as possible. Wait 1-2 minutes before applying next product.

Use only in the evening.

Start with using Il every other day.

Apply after cleansing and before moisturizing.

    This is the best vitC serum I’ve ever used. My skin is sensitive and acne prone. This skin tone evened out and my skin is glowing. I just got a decongesting serum and add it to Illumina. I’m in love! Hands down amazing

    After only a few nights of using this, my skin feels and looks way better than it did before!
    My night time routine was:
    Toner – right now, Ranavat Botanics Jasmine Tonique
    Essence cream
    Jade Tea Balm
    Then a facial oil – right now, Mahalo’s Queen Emma Oil
    I have switched out most of my other products with Moss and L4B products and my face is so thankful for it. Those unpleasant cystic hormonal acne spots around my mouth and jawline have been going away and my skin’s texture is so smooth and soft that I do the bad thing and constantly feel my face in the morning 😀
    I had one spot on my chin that was extremely painful and wasn’t coming to a head. I used a combination of Illumina, Leopard Spots and Quantum Glow in my day and night routines and within 4 days the pimple disappeared! AND none have come to replace it!
    This serum is hands down a keeper for exfoliating serums. I don’t need to use it every night, so I will be able to keep the product a little longer. I never thought that I would use all products from one company, I have always used one product here and one product there. But every product that I try is amazing and I keep checking back every week to see what new products are being created in L4B!

    Illumina has been a main stay in my skincare routine for some years now. When I use it at night my skin literally improves by the next morning. It’s absolutely worth the money, especially if you struggle with acne.

    I have noticed on the mornings after using Illumina my skin looks clearer, brighter and smoother. It is a regular part of my Moss skincare routine. Having acne prone skin it’s been such a relief to find products that treat both acne and aging. I can honestly say that Moss skincare is the only skincare line that I have stuck to for over a few months and I’m now going on over two years of using these great products. Illumina is one of my favorites!

    This serum keeps my skin clear. I don’t suffer from many breakouts, but this serum keeps my blackheads in check which is my main concern. I keep a back stock of this product because I don’t want to run out of it!

    Nothing keeps my skin clear like this product. I don’t notice much in way of improved brightness or clarity personally, but it does keep my cystic acne in check like nothing else.

    Received this in boxwalla- used it all up and was so impressed I purchased it again myself directly from moss. It is pricey, but worth it. For me, it calms and brightens, is gentle and effective. Will continue to purchase.

    Ilumina did not work for me. I have older, very sensitive skin and it just caused my face to breakout all over. I then tried it again after my skin cleared up and the same rash came back. I suspect it’s the Vitamin C. It may just be to strong for me. Of the many products of Moss I have tried this is the only one that I have had a reaction too.

    I have been using Il for over a year now and it is definitely an amazing product. It cleared my skin of horrible unsightly acne around my chin and now I only use it when I have a breakout coming. I do find it a little drying for my sensitive and thirsty skin but the results out way the problem. It’s the only Vitamin C product my skin can tolerate. After reading some reviews I think I’ll start using it as maintenance a couple of times a week to keep acne from surfacing- what a great idea! Thank you C for creating products us acne sufferers can use!

    Illumina and Potenci were literally answers to prayer, and I thank God for Celestyna’s scientific creativity and knowledgeable dedication to producing natural products that actually work on adult acne!! I had been struggling for almost a year with acne that appeared out of nowhere and was constant and unrelenting (new pimples everyday; some cystic, some pustules, dull skin, super dry and tight). I wasn’t sure why my skin was suddenly freaking out, and it was truly distressing. I very much wanted to do natural treatment so I did the whole oil-cleansing/oil-moisturizing thing first, and my skin actually got worse (like, worst acne of my LIFE). After praying for a solution and poring over the internet, as one does when acne seemingly devastates one’s life, I found a recommendation for Moss from some blogger, leading me to Celestyna’s blog on why hydric moisture (in addition to fatty acids, ceramides, etc.) is so important for maintaining a healthy skin barrier…this is sort of “duh”, but oils have been such the recent craze! I had been using all sorts of chemical exfoliants and hadn’t been using any kind of substantial hydric moisturizer (mainly oils), and realized that my skin was extremely dehydrated and damaged, and that was manifesting itself in constant breakouts. However, I still needed some gentle exfoliation to help with cell turnover, which Il provided, while Po nourished. I purged badly the first 3-4 weeks of use from all the congestion I had (be prepared for that, those of you who are in a similar situation as I was in), but even during that time, my skin was starting to feel more hydrated/comfortable and smoother, so I knew I wasn’t just having a bad reaction. It took about 2 months to see a significant decrease in acne. It has now been 6 months since using Il and Po (and also a couple other products that I had been using before), and I am so thankful to say that I don’t have any active pimples on my face right now and acne scars are fading!! Acne around my period has also decreased significantly, sometimes doesn’t even occur. My skin is so much smoother and brighter, and most of all, feels healthy and hydrated. I can’t say I have “fairy skin” or “skin of my dreams” as some reviewers have said here (woh-woh), but not having painful pimples, bumpy skin, blackheads, tons of acne scars, redness, and super tight and uncomfortable skin is SO WONDERFUL. I can only expect that my skin will continue to improve with use of Il and Po. As many have said, the cost is more than I would have ever dreamed of spending on skincare (I’m a drugstore/The Ordinary brand kind of girl)…but C’s generous discounts allowed me to try her trial duo of Il and Po, and WOW, so thankful to the Lord for that opportunity. I’m not sure how much longer I will use these products (I’ve ordered full sizes of both Il and Po since finishing the trial sizes) because of the cost, but what I have spent so far has been so well worth it. I feel more much educated about my skin and what it needs b/c of C’s expertise that she shares so freely, and I’m proud to tell people that it’s Moss’ natural skincare products–and not antibiotics or retinol–that have made such a huge difference in my skin. I seriously want to try all of C’s products, and I’m glad she has lower-cost options here and there in L4B so I can indulge a bit more. : ) Thank you Celestyna!

    Finally got myself a big treat. Illumina first use: embellishes the face with a luminosity and glow that stays and is noticeable! Continued use (3weeks) has evened out my complexion, and helped with redness of my current acne breakouts! Under eye darkness has been noticeably decreasing!
    So Grateful to Celestyna!

    I have very sensitive, fair, and acne-prone skin so it makes it really difficult trying new products, but I have had zero problems with this one! In fact, if I’m having a reaction to another product, I’ll use Illumina twice a day to calm my skin back down. I highly recommend this product.

    This stuff is great. I have seen a big difference in my hyper-pigmentation as well as my skins overall texture since I began using Ilumina. It may be pricey, but Ilumina and the Moss Skincare line been a game changer in clearing up my acne prone skin. I will never be without this product.

    Illumina is excellent for all-around skin support. I don’t have acne (although I did in my twenties and thirties), but definitely saw so much improvement in my skin’s texture and radiance when using this product. Highly recommended.

    Love, love, love!!! I first discovered Illumina through Boxwalla in 2018 and after using it for a couple weeks I was hooked. Illumina is the only vitamin C product that hasn’t caused my skin to develop small acne like bumps. On top of that, using Illumina 3 times a week has kept my skin free of any cycle related breakouts, including those pesky cystic bumps that used to happen on my chin. My skin has never looked better and continues to improve the longer I use this serum. I can’t imagine ever being without this product…have a backup bottle stored in the fridge. It is a pricey product, but it is honestly worth every penny because the formulation is unmatched.

    This product is the best thing that will ever happen to your skin. It has saved my skin time and time again. In my thirties my skin went from clear to full blown acne. Moss products are what brought my skin back to normal. Then a few years later I got pregnant and my skin returned to full blown acne…again Moss to the rescue. Within two weeks my skin is clear and glowing beautifully once again!! I will never be without this in my skin care Arsenal.

    Ilumina is definitely effective. It’s not irritating and a very powerful serum. I don’t have a lot of acne anymore, due to diet. Whatever comes up, Ilumina keeps it in check. I also experienced brightening effect. My melasma seems lighter. My whole skin seems brighter and more balanced. Just ordered my 4th bottle.

    I received this in my Boxwalla box and so far, so good, I really do like it – but nowhere can I find the concentration of LAA that it contains? Is it listed somewhere and I just missed it?

    After approximately 3 and a half weeks of using Illumina, it did everything for my skin in one fell swoop that I’d been attempting to get from several different products for years. It’s returned to me that even, luminous skin tone & smooth, supple texture of my youth with a drastically reduced appearance in pores – it’s literally Fairie Skin in a bottle.

Illumina is definitely one of my favorite products that I cannnot do without.

I needed something that would help with congestion, but also be gentle enough on my rosacea, and I`m happy to say I`ve had zero problems with this. I have been using this regularly since July. And I`ve recently been using this every other night, and it has made a huge difference in my hormonal acne. A little goes a very long way, and it`s just a wonderful product.

I use it every other night. Once I apply Potenci afterwards for the night, I wake up to glowy, happy skin. The combo of the two products (IL and PO) are sheer perfection. My husband even notices my skin in the morning and he doesn’t notice anything. I’m impressed.
