Frequently asked questions
Can I use Hydroquinone and Niacinamide together?
Yes, it is safe. There is no known chemical conflict between Hydroquinone and Niacinamide, and neither makes the other less effective. They share a goal (pigmentation), so together they reinforce each other.
Which goes first, Hydroquinone or Niacinamide?
Apply Hydroquinone first, then Niacinamide. The general rule is thinnest to thickest texture, and lowest pH first.
Should I use Hydroquinone in the morning or at night?
Hydroquinone: best at night. Use only under a dermatologist's guidance, typically nightly on the dark patches for up to 3 months, then take a break. Strict daily sunscreen is required or results reverse.
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.
Is Hydroquinone with Niacinamide safe during pregnancy?
Hydroquinone is generally avoided during pregnancy and breastfeeding. Ask your doctor about safer alternatives such as azelaic acid or bakuchiol.
