What retinol does for your skin

Retinol · Vitamin A · all-trans retinol

TextureEvennessClarity

Retinol is a vitamin A active and one of the most-researched ingredients out there for the look of fine lines, uneven texture and blemish-prone skin. In cosmetic terms it refines and evens. It's a night active that rewards patience: start slow, keep it consistent, and give it a few weeks.

What Retinol is

Retinol is a vitamin A derivative used at night. It's a slow-and-steady active, not an overnight one. In the first few weeks your skin may look temporarily less settled while it adjusts. That's a normal adjustment phase, and it passes. The fix is to ease in rather than pile it on.

What Retinol is good for

the look of fine lines and early signs of ageing
uneven or rough-looking texture
blemish-prone skin that wants a night active
a generally uneven-looking tone

How to use it

Always at night, never in the morning.
Ease in slowly: about 2 to 3 nights a week to start.
Expect an adjustment phase in the first few weeks; ride it out rather than stopping and starting.
Wear SPF every morning while you use it, since it makes skin more sun-sensitive.

What it pairs with

Keep retinol away from benzoyl peroxide, vitamin C and exfoliating acids in the same routine. If you also use benzoyl peroxide, put that on in the morning and save retinol for the night. Baselit checks every pairing so nothing in your routine clashes.

Frequently asked questions

What does retinol do for skin?

In cosmetic terms, retinol refines and evens. It's a vitamin A night active used for the look of fine lines, uneven texture and blemish-prone skin. It works gradually, so the key is consistency over a few weeks rather than a quick fix.

How do I start using retinol without irritation?

Ease in slowly, about 2 to 3 nights a week, always at night, and don't layer it with other strong actives at first. A short adjustment phase in the early weeks is normal. Wear SPF every morning while you use it.

Can I use retinol and vitamin C together?

It's best to separate them: vitamin C in the morning, retinol at night. Keeping strong actives apart keeps your skin comfortable and lets each one do its job. Baselit's routine builder separates them for you automatically.

Is retinol safe during pregnancy?

Retinol is one of the actives many people choose to skip during pregnancy or breastfeeding. Baselit swaps it out of pregnancy-aware routines in favour of gentler tone-evening options. When in doubt, check with your doctor.

What's the difference between retinol and retinal?

Retinal (retinaldehyde) is retinol's faster sibling, one conversion step closer to the active form, so skin often sees the look of results a little sooner. The usage rules are the same: nights only, ease in slowly.
