Retinal
Ingredient Info
Retinal is a form of vitamin A that works as a precursor to retinoic acid, the active compound that drives skin renewal. It helps regulate skin cell turnover, support collagen health, and influence pigmentation processes in the skin.
Benefits
- Promotes skin cell turnover and renewal
- May help with signs of aging and skin texture
- Supports skin's natural repair processes
- Influences melanin regulation and skin tone
Potential concerns
- Can cause irritation, redness, and dryness when first introduced
- May increase sun sensitivity—daily SPF is essential
- Not recommended during pregnancy due to vitamin A concerns
- Can be destabilizing in formulations; may degrade when exposed to light or air
Science: Research confirms retinal is a key metabolite of vitamin A that regulates skin cell function and influences melanogenesis, though the exact mechanisms in topical skincare require further study. Both insufficient and excessive vitamin A can cause problems, so appropriate dosing and gradual introduction are important.
