No fungal-acne, pore-clogging, fragrance or drying-alcohol flags for Retinal in our reference data. It is commonly flagged for caution in pregnancy — confirm with your own doctor.
Retinal (retinaldehyde) is a vitamin A derivative that converts to retinoic acid in the skin, promoting cell turnover, collagen synthesis, and improvement of fine lines, uneven tone, and acne. It is generally considered more potent than retinol but better tolerated than prescription retinoic acid.
