What Retinal does
Retinaldehyde is one conversion step closer to retinoic acid than retinol, so it works faster than retinol while usually being gentler than tretinoin. It also has a mild antibacterial effect useful for acne.

Frequently asked questions
Can I use Retinal and Tea Tree Oil together?
Yes, it is safe. There is no known chemical conflict between Retinal 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, Retinal or Tea Tree Oil?
Apply Tea Tree Oil first, then Retinal. The general rule is thinnest to thickest texture, and lowest pH first.
Should I use Retinal in the morning or at night?
Retinal: best at night. Start at 0.05% two or three nights a week and build up slowly. Buffer with moisturiser if you are sensitive, and wear SPF daily.
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 Retinal with Tea Tree Oil safe during pregnancy?
Retinal is generally avoided during pregnancy and breastfeeding. Ask your doctor about safer alternatives such as azelaic acid or bakuchiol.
