coxirINTENSIVE EGF PEPTIDES SERUM l EGF(Epidermal Growth Factor)-Firming, Smoothing & Hydration with Peptides and EGF–Fragrance-Free for Sensitive Skin l Korean Skincare (1.69 Fl Oz (Pack of 1)

Love COSRX, I purchase all of their products. I've used them for about four years now and everyone including my esthetician think I look 10 years younger...I'm 61.

I really enjoy this and will keep using.

Good amount of product. Good quality. It’s definitely acceptable especially for the price point. The consistency is a bit of a gel and slightly (only slightly) sticky. I prefer the lighter serums that feel a bit more silky/watery. I will probably try another product with growth factors after I finish this one. I recommend this product if you want to stretch your dollar - quality active ingredients for a good price. This brand delivers great value.

I have never used a gf serum before and honestly didn’t have high expectations of this product. However. I’m halfway through the bottle and I see a difference in my skin,, particularly the crepey undereye area. I had a fold/crease under one eye every morning from sleeping on my side. It had been there for years and was forming a wrinkle. Now when I wake up that fold is not there! I will definitely reorder this product and highly recommend. I have extremely sensitive skin and this caused no irritation or breakouts. Great product.

This has a thick gel texture. It’s hard to say if it’s having any particular effect but I’ve only been using it for a few days. I like the way it feels - very slimy and thick - like snail slime, haha. The EGF is supposed to have real, actual functional benefit in tissue repair. Be aware that this formula does contain copper - it’s way down the ingredient list. It’s not an issue for me but you might want to use it separately from your vitamin C.

Not wildly impressed. I wouldn’t purchase again but the price was worth giving it a try.

Amazing amazing I love ALL THEIR PRODUCTS!!!!!!

I recently decided I needed to overhaul my 14 step all k-beauty routine for something more simple, because spending an hour on skin care every night is no longer where it's at for me every day. This replaced two mixsoon products for me and is REALLY effective, especially in combination with the COS-RX "the 6 peptide skin booster". The combination of the two has improved my fine lines around my eyes, and seriously improved my skin texture.For context, I'm 42/white/AFAB with rosacea and ultra pale skin with olive undertones.
