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.

What Vitamin C does
A powerful antioxidant that brightens dull skin, fades dark spots and boosts your sunscreen's protection against free radicals. Pure L-ascorbic acid works best at a low pH and oxidises (turns orange) quickly.

Frequently asked questions
Can I use Retinal and Vitamin C together?
Yes, but not at the same time. These do not cancel each other out, but both can irritate, and they work best at different pH levels. The easy fix is vitamin C in the morning (where its antioxidant protection matters most) and the retinoid at night.
Which goes first, Retinal or Vitamin C?
Apply Vitamin C first, then Retinal. The general rule is thinnest to thickest texture, and lowest pH first. For this pair, though, it is better not to layer them in the same routine at all.
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 Vitamin C in the morning or at night?
Vitamin C: best in the morning. Apply in the morning on clean skin before moisturiser and sunscreen. Store it away from light and heat, and throw it out once it turns dark orange.
Is Retinal with Vitamin C safe during pregnancy?
Retinal is generally avoided during pregnancy and breastfeeding. Ask your doctor about safer alternatives such as azelaic acid or bakuchiol.
