Retinoid
An over-the-counter retinoid (vitamin A derivative) converted in the skin to active retinoic acid.
Supports cell turnover and collagen over time; improves the look of texture, tone, and fine lines with consistent use.
Serums and creams, often 0.1–1%; used nightly, introduced gradually.
Clients targeting aging, tone, or texture with tolerant skin.
Can cause dryness, peeling, and sensitivity at first. Avoid pregnancy/breastfeeding. Do not combine with strong acids in the same step. Sun sensitivity increases.
It is not the same as prescription tretinoin (stronger). Initial flaking is adjustment, not an allergy.
Separate from AHAs/BHAs, vitamin C (if irritation), and benzoyl peroxide (can inactivate).
Frame as 'slow and steady' — start 2–3 nights, build up, always with SPF and a supportive barrier routine.
