Retinaldehyde
One step from retinoic acid, faster acting than retinol, still avoided in pregnancy. Pairs with acid exfoliants and vitamin C fine at sensible strengths - alternate AM/PM or nights if skin gets irritated, but it isn't a hard conflict.

- Targets: fine lines, breakouts, texture, dark spots
- When: Use in the evening.
- Pregnancy: commonly avoided during pregnancy and breastfeeding, check with a professional.
