A Peptide Heaven in a Bottle
I bought this as a substitute for the CORX multi Peptide serum which’s always sold out, and was not disappointed. It’s a clear, odorless thick formula, but light to the touch with no greasy feel, it absorbs quickly, and it has a matte finish once it’s fully absorbed by the skin. It also has a plumping, and helps absorb my other skin products better, that is why it’s also a great primer before makeup. Been using it for a while now and it works, makes my skin feel firm, plump, and super soft, really great product, and actually more potent than the CORX formula because it has 9 different types of peptides plus other active compounds! Can’t recommend enough!!

Changes in Skin texture and redness is a benefit of this serum.
This serum is AMAZING! I have been using it for a few weeks and can already see a difference in my skin. This is definitely going to be a staple in my skin care routine.

Permanently added to my routine after 30 days
I cannot believe how good this is!This 9 Peptide Skin Booster from TOSOWOONG changed my entire routine. From the first time I used it, my skin felt firmer, smoother, and just more alive. I have sensitive skin and use Tazarotene, so I was nervous — but this? No stinging, no dryness, just hydration and glow. I layer it right after toner, and it soaks in beautifully. My jawline feels tighter, and even my under-eyes look better. It works so well with my red light routine too. I honestly look forward to applying it every day. This bottle is staying in my top shelf — period.

Gooey texture
This one I was not impressed with as it leaves a greasy texture and and broke my face out. So, I tried it on my body next to try to use it up but still gross. No smell just yucky to the feel. It also was not very good for dryness but this could be due to the fact that I could not use it long as it broke me out.

My skin looks and feels amazing!
I absolutely love this product and skin care line! COSRX is a Korean based skin care company without all of the chemicals and other unnecessary additives. I use the peptide booster in conjunction with the snail serum and the hyaluronic acid face cream. I noticed a difference within a week. My skin looked softer and after a couple of weeks, I noticed my fine lines diminishing.

I liked this a lot. It’s extremely watery, but feels beautifully hydrating on the skin, and they hydration lasts a good full day. I found it really nice to use after bathing, showering, or washing my face as it gives a nice smoothing sensation to my dry skin and plumps it up. You can layer with moisturizers for added moisture but I found I didn’t need it after this, even though my skin runs on the dry side.It’s got no scent and is gentle on my sensitive skin. It’s not greasy, thick and has no yucky dimethicone (which my skin absolutely hates). The niacinamide in this evened out my skin tone and gave me a nice glow. About the only drawback is the peptides in this are at the bottom of the ingredient list which means they are less than the niacinamide and hyaluronic acid in it, but it does have them, so that is a nice bonus to a very nice serum.The other Tosowoong hyaluronic serum/cream I tried (hyaluronic acid 9) broke me out a little, this one does not and so I prefer it over all. My skin doesn’t love hyaluronic acid sometimes but tolerated this one really well. As with all hyaluronic acid products, you may need to hydrate with a mist after application in dry climates as sometimes hyaluronic acid can pull moisture instead of acting as a humectant.Overall this is one of the best hyaluronic acid/peptide serums I have used– as usual K-beauty skin care is on another level. I am really impressed with this and would obtain it again.

This has the consistency of a toner rather than a serum….it’s more watery but in saying that, it absorbs quickly and provides a nice base for layering. Cant go wrong with Korean skin care products!
