Retinol,
explained in full.
It works. It is also the active people give up on most — almost always because they started too strong, too fast.
What it is
Retinol is a vitamin A derivative. Applied to the skin, it speeds up the turnover of surface cells and stimulates collagen production — the protein that gives skin its firmness.
It is one of the most studied actives in skincare. It is neither new nor a fad.
Why it matters here
The double edge
Retinol acts on dark spots, texture and loss of firmness — three common concerns for melanin-rich skin. But irritated melanin-rich skin can leave a lasting pigmented mark. The risk is not the irritation, it is what it leaves behind.
Hence the rule that governs everything else: you go slowly, and that is the method, not excessive caution.
Who it is for
It is for you if
- You are starting to see wrinkles or loss of firmness
- You have dark spots or uneven skin texture
- Your texture bothers you
Wait if
- You are pregnant or breastfeeding — see Caution below
- Your skin barrier is already damaged — repair it first
- You have just started another strong active — one at a time
When
In the evening, and there is a reason
Retinol breaks down in light and increases sun sensitivity. And above all: between 11 p.m. and 4 a.m., collagen production peaks following the skin's circadian rhythm. So you apply the active when the skin is working hardest.
How — the three months
Once or twice a week
The lowest concentration, in the evening, on thoroughly dry skin. Moisture increases both penetration and irritation.
Increase the frequency
Only if no irritation lingers. Otherwise, stay on month 1 for as long as it takes.
Raise the concentration
Toward 0.5% if your skin keeps up. Otherwise keep what works — there is no prize for going higher.

The full range runs from 0,025 % à 0,5 %, over about three months.
What comes next
Never the same night
- Retinol and AHA/BHA — over-exfoliation
- Retinol and vitamin C — they cancel each other out
Alternating works: retinol on even nights, exfoliant on odd nights.
The next morning's non-negotiable
Sunscreen in the morning, no exceptions. Retinol increases sun sensitivity — without protection, you cancel the benefit.
Caution
Contraindication
Retinol and vitamin A derivatives are contraindicated during pregnancy and breastfeeding. So are AHAs and BHAs at high concentrations.
Slow down if
- Tightness lasts more than a day
- The skin visibly flakes
- A burning sensation appears on application
These are not required stages. They are signals to go slower.
