About

Nitavera is a free web tool for people who use more than a couple of skincare products. Add what's on your shelf and it flags common ingredient clashes (like retinol with glycolic acid on the same night), then tells you what to split up, alternate, or move to morning vs night. It also gives you a simple AM/PM order. There's an ingredient checker and an optional on-device photo check for visible redness, oil and texture; photos stay on your device. Cosmetic guidance only, not medical advice. No brand money or affiliate payouts.
