KFan review for No.4 Collagen 73% Pudding Serum

Impressive % of collagen in this product was what tempted me to try it. Featuring: 📌 2 types of collagen 📌 multiple HAs 📌 hydrolized elastin, keratin, silk 📌 niacinamide 📌 peptides 💬 My thoughts & experience: based on the composition, I expected this serum to be profoundly slow-aging. My face along the jaw line is showing first signs of sagging skin, so I wanted to get a product targeting this concern. Well, I don't see it working, unfortunately. It's a basic moisturizing product and nothing more, IMO. It has interesting bouncy pudding-like texture, which is enough for oily skin to be used in place of a moisturizer, which I sometimes do. I actually massage it a little bit to facilitate absorption as it takes some time to absorb fully. It leaves a slightly tacky feel and moist look. 💡 Tip: applying to skin that's still a bit dump right after toner actually helps with absorption and to avoid tackiness. Overall, the product might be worth a try for some, but since for me the functionality of it is somewhat undistinguished, I won't repurchase.
