Frequently asked questions
Can I use Lactic Acid and Urea together?
Yes, and they work even better together. Urea cushions Lactic Acid: it hydrates and supports the barrier while the active does its work. That means less irritation and better results.
Which goes first, Lactic Acid or Urea?
Apply Lactic Acid first, then Urea. The general rule is thinnest to thickest texture, and lowest pH first.
Should I use Lactic Acid in the morning or at night?
Lactic Acid: best at night. Use 2–3 nights a week. It is good for beginners to exfoliation. Follow with a moisturiser, and wear SPF the next day.
Should I use Urea in the morning or at night?
Urea: works morning or night. Use 5–10% on the face or body daily. Higher strengths can sting on broken or freshly exfoliated skin.
