VT Cosmetics Vitamin C Astaxanthin Serum is a light, watery Korean vitamin C serum for a dull, uneven-looking tone and a fresh glow. I suggest it if pure vitamin C serums sting on your skin and you would like a gentler vitamin C formula.
It combines four forms of vitamin C (ethyl ascorbic acid, ascorbic acid, sodium ascorbyl phosphate and ascorbyl glucoside) with astaxanthin, an orange-red antioxidant from algae, plus niacinamide, glutathione, kojic acid, ferulic acid and several sizes of hyaluronic acid. Its base is yuzu fruit water, and it contains yuzu peel oil and limonene, which give it a fresh citrus scent. If your skin reacts to fragrance, test it on a small area first.
🔬 Does vitamin C on the skin really make a difference?
In a double-blind study, 19 women applied a 5% vitamin C cream to one side of the neckline and one forearm, and the same cream without vitamin C to the other side, for six months. The visible sun-damage score fell from 6.7 to 4.4 on the vitamin C side, a significant change, and from 6.7 to 5.3 on the other side, which was not significant.1 To be honest, the study was small, two authors worked for the cream's maker, and it tested pure ascorbic acid at 5%. This serum uses a mix of milder vitamin C forms in amounts the brand does not publish, so I see it as a gentle, everyday glow helper, always with daily sunscreen.
Questions about VT Cosmetics Vitamin C Astaxanthin Serum
Morning or evening?
Both work. In the morning it adds antioxidant protection under your sunscreen, but it does not replace sunscreen.
Can I use it with retinol?
Yes, at different times of day: vitamin C in the morning, retinol in the evening.
Will it turn brown in the bottle?
Milder vitamin C forms are more stable than pure ascorbic acid. Close the bottle well after use and keep it away from heat and sunlight.
