An essential oil with modest evidence against mild acne. It works more slowly than benzoyl peroxide but causes less dryness. Undiluted it can irritate or sensitise skin, so it belongs in a formulated product.

Frequently asked questions
Can I use Niacinamide and Tea Tree Oil together?
Yes, it is safe. There is no known chemical conflict between Niacinamide and Tea Tree Oil, and neither makes the other less effective. They share a goal (acne), so together they reinforce each other.
Which goes first, Niacinamide or Tea Tree Oil?
Apply Niacinamide first, then Tea Tree Oil. The general rule is thinnest to thickest texture, and lowest pH first.
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.
Should I use Tea Tree Oil in the morning or at night?
Tea Tree Oil: works morning or night. Use a product with around 5% tea tree, or dilute it. Never apply the pure oil straight to the face. Patch test first.
Is Niacinamide with Tea Tree Oil safe during pregnancy?
Neither is a known risk in normal cosmetic amounts, but guidance varies for Tea Tree Oil. Check with your doctor.
