- How strong is the vitamin C compared with other serums?
- It uses 12% pure L-ascorbic acid, a mid-to-high over-the-counter strength. Several rival serums go to 15-20%, which may suit experienced vitamin C users but can irritate beginners.
- Can I use it if I have sensitive skin?
- It is formulated for sensitive skin and is non-comedogenic, but it also contains salicylic acid. Patch test first and start every other day if your skin reacts easily.
- When should I apply it?
- It can be used morning and evening on clean skin before moisturizer. In the morning, follow with sunscreen, since vitamin C supports but does not replace sun protection.
- Why did my serum turn yellow or brown?
- Pure vitamin C oxidizes when exposed to air and light, and the color shift signals it is losing potency. Keep the cap closed, store it away from light and heat, and use it within the period on the label.
- Does it replace a moisturizer?
- No. It is a lightweight serum, so follow it with a moisturizer, especially if your skin is dry or you use it in the evening.
- Is it suitable for men and teenagers?
- It is made for adult skin and is not marketed for children or babies. Anyone adult with a normal skin barrier can use it regardless of gender.
