Ruruberry - danielwonderland review for 18% Ethyl Ascorbic Acid Booster Drop

◼ 18% Vitamin C (Ethyl Ascorbic Acid): One of the vitamin C derivatives with high stability and not easy to be oxidized. By inhibiting the activity of tyrosinase and blocking the formation of melanin, it has whitening and freckle-removing, antibacterial and anti-inflammatory effects. At the same time, it improves dull skin, repairs skin cell activity, promotes collagen production, and has anti-oxidative and anti-aging effects. ◼ Superoxide Dismutase + Glutathione + Ferulic Acid: The main functions are whitening, freckle, wrinkle removal and anti-aging. ◼ Contains 18% high-concentration Vitamin C (Ethyl Ascorbic Acid), which is a very stable and low-irritating whitening ingredient, which can be used even for sensitive skin. ◼ Cruelty and fragrance free. ◼ The light black serum has high fluidity. It is quickly absorbed by the skin after application, one pump is the limit, because using more than one pump will cause a sticky feeling. ◼ I used this serum for night skin-care routine for up to 2 weeks. My skin condition was very stable in the first week. During this period, I used it with different lotions and creams without any discomfort. In the second week, my chin around will pop up one or two pimple, but the overall skin condition is still good. ◼ Since it's not really moisturizing, the skin starts to produce a lot of oil about 4 hours after use. Compared to my skin condition before using it, the redness problem has improved quite significantly, and my complexion also brighten one tone. The fine lines around the eyes are also reduced a lot. Other than not liking the smell and not moisturizing enough, overall I'm satisfied, if it improved the smell and moisturizing a little more, this would be the perfect whitening serum.
