Frequently asked questions
Can I use Lactic Acid and Niacinamide together?
Yes, it is safe. There is no known chemical conflict between Lactic Acid and Niacinamide, and neither makes the other less effective. They share a goal (pigmentation), so together they reinforce each other.
Which goes first, Lactic Acid or Niacinamide?
Apply Lactic Acid first, then Niacinamide. 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 Niacinamide in the morning or at night?
Niacinamide: works morning or night. Use morning, night or both, after water-based serums. 4–5% is enough for most people. Very high percentages can cause flushing on sensitive skin.
