4.95 out of 5


A lightweight serum that is 31% peptides by weight designed to support dermal integrity, address wrinkles and diminish acne scars.

There are seven peptide complexes in total in this product.

Some peptides use pre- and post-synaptic technology to provide a temporary relaxing of the muscles causing expression wrinkles. The closest you can get to botox in a bottle.

Some peptides perform cutaneous restructuring and repair, and general skin rejuvenation, diminishing acne scars over time. We use next generation Matrixyl (Synthe 6) and a second peptide that has been shown to outperform Matrixyl (which is the leading standard for acne scarring).

There’s a peptide complex that reenergizes epidermal regeneration (ie skin cell turnover).

There’s a peptide complex created for skin elasticity and tightness enhancement which works by reducing the enzyme elastase activity.

This serum is an amazing 31% peptides by weight.

Light floral scent.

    I bought this the moment it came out. I have noticed improvement around the eyes and forehead. I am motivated to find effective, honest brands an Moss never lets me down.

    I recently found out that peptides are a “hero” ingredient for your skin, so my search for a peptide product began. I knew I wanted a peptide serum that didn’t have a bunch of icky ingredients in it, so I stumbled upon this product. I love how light and fast absorbing it is! I’ve also seen some softening of fine lines that have begun to develop. I will not be without this product now that I’ve discovered it!

    I’m so happy with this lovely serum. I’m 38 and most of my concerns these days are with aging and reducing scarring. I’m not sure I’ve ever written a product review for face products, but I looked in the mirror the other day and I noticed the scarring on my cheeks and chin had filled in significantly and it dawned on me it was the Soiree working. I use it twice a day. I’m so impressed and grateful for the constant research and creativity Celestyna puts into Moss!!!

    What a wonderful product! I have been using it for about 2 months now along with Potentci and it has softened my acne scars and helped with fine lines, giving me a lovely glow. I’m looking forward to even better results with consistent use. Highly recommend!

    I am glad to see products at moss for the more mature skin. My acne days are over and this is just what I need. A very lightweight serum and yet absorbed quickly into my skin. I absolutely love the silky soft feeling that Soirée complexion lifting complex delivers. I am looking forward to seeing the results of younger looking skin!

    I am thrilled with the results I am seeing from using Soiree, formerly Peptide Party in L4B. My skin looks healthy, plump and glows. It has greatly improved my deep expression lines also. I use it almost every night, mixing it with L4B CR Citrine Suspension. This will be a permanent addition to my skin care…..forever. I have waited decades for a product this perfect!

    Peptide Party Serum (now Soirée) is such an incredible product. My skin looks so healthy. I’ve been using it for about two months now and my skin is smooth and even. And for the first time in a long time, I’d even say it my skin is glowing. I have complicated skin – with a history of adult acne and sun damage – and Moss products have kind of changed my life. I don’t have to worry about acne any more because of these products! But this is by far my favorite yet.

    I can really feel this decadent serum firm my skin! It penetrates beautifully and I use it before Il and Po – all truly AMAZING products. I am so thankful for this formula. ❤️

    I purchased Peptide Party as part of L4B, and it is FORMIDABLE. (As it should be! I had never splurged on a high-quality peptide product before…but I’ve come to trust that when Moss makes an intense/expensive product, it’s worth it.) My skin doesn’t respond well to layering/high numbers of products, so I haven’t quite worked out how to work this as a permanent addition to my everyday routine, but I did use it for a nice span when my skin was having a hard time earlier this summer (dull, reactive, unusual dry spots) and I was *very* please with the results. Sinks in well and leaves my face feeling nourished and calm, very pampered. I can’t invest in it again right this minute, but when I can, I will be excited to repurchase.

    I’m nearing the end of my first bottle of Peptide Party and already bought my backup. 🙂 I was dealing with fine lines around the eyes and forehead and after using this while increasing the hydration in my regimen, they are disappearing! it will take time and you must be patient but in my experience, it works! 🙂

    I’ve been using this since it was peptide party serum and it’s amazing. I had a fairly deep chickenpox scar on my forehead and within a month of daily use it was plumped up and basically gone.

    It sinks into skin super easily, isn’t greasy, and is easy to mix with other products.

    I’m hopeful to see it’s effect on expression lines and wrinkles with continued use.

    Excellent product.

    I recently began using peptide party (now named Soiree) and love it. The fomula is light and super easy to work into my morning and evening routines. Soiree is the only peptide formula I’ve ever seen with this concentration and variety of peptides, and research suggests you need a high concentration to see results. So while I’ve not been using it long enough to see all the results promised, I’m sure it will deliver just like Illumina and Potentci have for me.

    I absolutely love the Peptide Party (Soirée) serum! I didn’t think I was old enough to benefit from peptides but boy was I wrong. This stuff wasn’t sticky , layers well, and made my skin look young and plump. I’m a believer!!

    The Peptide Party (now Soirée) is hands down the best anti-aging serum that I have ever used. I’m so happy that it is now a permanent part in the moss collection! It’s super lightweight, yet decadent, and makes my skin feel so smooth, firm and youthful. This includes so many peptides – not that I’m complaining! Seriously, give me all the peptides! If you’re on the fence, I say definitely try it. You won’t regret it!

    LOVE the (formerly known as) peptide party/soiree!!!!!! I’ve used 3 different iterations and am so pleased it will be available as part of Moss now. Helps immensely with my fine lines and acne scars. A great addition to Il and Po in my routine!

    Botox in a bottle! I experienced severe acne when I was in high school and left me with terrible scars and uneven texture! I have been following Moss and L4b for a while and debating on if I should place an order of the peptide serum. When I saw CelestyNa’s email about the peptide serum improved her scars, I was sold at that moment! I am not type of person to leave reviews on a product after a single use or without finish the bottle. But OMG!!!! I used this peptide serum on my face and I noticed a huge difference on my skin the very next day! My scars look more plumped, less bumpy, and my overall appearance and skin texture are so much better!

    I’m so glad the magnificent Peptide Party has graduated to Moss as Soirée. It is a fascinating formulation. I use it nightly and feel my skin drink it in. The result is a blurred, plump, calm, smooth surface. Looking forward to the long term benefits.

    I purchased the PEPTIDE PARTY serum several months ago and I am LOVING IT! I am thrilled to see it as part of the permanent MOSS skincare lineup…..I was nervous thinking that I would not be able to get it after loving it so much. It is an exquisite formulation……it plays well with other products as it has a watery consistency…it sinks right into the skin. It is a one-stop-shop………ALL the peptides you will every need. It is an extravaganza of firming, scar and wrinkle-reducing peptides. Buy it… WILL NOT be disappointed!

    I’ve used Peptide Party and love it! So excited that it’s officially added to the collection as soirée. It feels great and sinks into skin without leaving any residue-feeling. My skin tends to be on the picky side and breaks out easily and I’m happy to say this caused zero bad reactions!
