Overview

Retinal (2% liposomal) — potent vitamin A derivative; start slowly (2-3x/week) to build tolerance as it can cause dryness, redness, peeling, or irritation, especially for sensitive or retinoid-naive skin.
Use broad-spectrum SPF 30+ daily during and after use, as retinoids increase photosensitivity.
Avoid combining with strong acids (AHAs, BHAs), benzoyl peroxide, or other retinoids to prevent excessive irritation.
Suitable for mature or aging skin; patch test recommended; not ideal during pregnancy or breastfeeding due to vitamin A content.
Black ginseng extract (58%) and supporting actives (niacinamide, bakuchiol, peptides, tocopherol) are generally well-tolerated with low irritation potential at these levels.
