Frequently asked questions
Can I use Glycolic Acid and Urea together?
Yes, and they work even better together. Urea cushions Glycolic Acid: it hydrates and supports the barrier while the active does its work. That means less irritation and better results.
Which goes first, Glycolic Acid or Urea?
Apply Glycolic Acid first, then Urea. The general rule is thinnest to thickest texture, and lowest pH first.
Should I use Glycolic Acid in the morning or at night?
Glycolic Acid: best at night. Use 2–3 nights a week after cleansing. Skip it on nights you use retinoids. Sunscreen is non-negotiable because AHAs raise sun sensitivity.
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.
