Questions

Can I use retinol in pregnancy?

No. Ask your doctor; azelaic acid and niacinamide are common alternatives.

What if my skin purges?

Mild purging for two to four weeks is common with retinol. Reduce to twice a week; stop if it burns.

Not sure where to start?

Tell us your concern and routine; we suggest one active to begin with.
