Questions

Can I use retinol while pregnant?
Most guidance advises avoiding retinol during pregnancy as a precaution, based on the known risks of high-dose oral vitamin A derivatives rather than direct proof of harm from topical cosmetic use. This is a caution, not a cosmetic safety verdict, and is worth discussing with a doctor rather than treated as settled.
Why does retinol irritate skin?
Retinol speeds up skin cell turnover, which commonly causes dryness, flaking, and stinging while skin adjusts, especially at higher concentrations or with frequent use. This is the expected, dose-related tradeoff of an active ingredient, not a defect.
