Retinol vs Retinaldehyde: A Beginner's Guide to Vitamin A
Vitamin A is the most studied ingredient in anti-ageing skincare, the closest thing we have to a true all-rounder for smoother, firmer, clearer-looking skin. But the names are a maze: retinol, retinaldehyde, retinoid, retinoic acid. Let's make it simple.
It's all about the conversion
Your skin can only use vitamin A in one final form: retinoic acid. Most over-the-counter products contain a precursor that your skin converts into that active form, and the number of conversion steps affects both strength and gentleness.
- Retinol needs two conversion steps. It's gentle, widely available and a brilliant starting point.
- Retinaldehyde (retinal) is just one step away from the active form, so it tends to work faster, while still being well tolerated by many people.
Neither is simply "better". Retinol is a gentle, reliable introduction; retinaldehyde is a step up in efficiency for those ready for it.
The quick version
- Best for: fine lines, uneven texture, dullness and congestion.
- Retinol: gentle, great for beginners.
- Retinaldehyde: faster-acting, a natural next step.
- Golden rules: start low and slow, use at night, and wear SPF every morning.
How to start without the drama
The classic mistake is too much, too soon. Begin once or twice a week at night, on dry skin, and build up as your skin adapts. A little tingling or light flaking early on is common; persistent redness means you're going too fast. Because vitamin A renews the skin's surface, daily sun protection is essential, see our Sunscreen collection.

Frequently asked questions
Can I use vitamin A every night?
Eventually, many people do, but build up to it. Starting nightly straight away is the fastest route to irritation.
Should I avoid it in summer?
You can use it year-round with diligent SPF. Many people simply prefer to begin in the cooler months.
Is it safe during pregnancy?
Vitamin A derivatives are generally avoided in pregnancy and breastfeeding. If this applies to you, please speak to your doctor before use.
