Frequently asked questions
Can I use Retinol and Tea Tree Oil together?
Yes, it is safe. There is no known chemical conflict between Retinol 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, Retinol or Tea Tree Oil?
Apply Tea Tree Oil first, then Retinol. The general rule is thinnest to thickest texture, and lowest pH first.
Should I use Retinol in the morning or at night?
Retinol: best at night. Start 2–3 nights a week on dry skin, a pea-sized amount for the whole face, then build up. Always wear sunscreen the next morning.
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 Retinol with Tea Tree Oil safe during pregnancy?
Retinol is generally avoided during pregnancy and breastfeeding. Ask your doctor about safer alternatives such as azelaic acid or bakuchiol.
