Retinol: Why Most People Start Too Fast

The usual retinol story goes like this. You buy it, you are enthusiastic, you use it every evening. Around week two your skin starts flaking and stinging, you decide it is not for you, and the bottle sits in a drawer.

Almost nobody quits because retinol does not work. They quit because of the pace.

What retinol does

Retinol is a form of vitamin A. It speeds up how quickly skin cells are replaced and it stimulates collagen production. In practice that shows up as smoother texture, fewer clogged pores and, over months, softer fine lines.

It is one of the best-evidenced ingredients in skincare. It is also one of the most demanding, because that same speeding-up is what makes skin dry and sensitive while it adjusts.

Why the form on the label matters

Your skin can only use vitamin A in one final form, retinoic acid. Everything else has to be converted first, and every conversion step costs strength.

Form	Conversion steps	In practice
Retinyl palmitate	Three	Mildest, slowest, good for building up
Retinol	Two	The standard in cosmetics
Retinal (retinaldehyde)	One	Faster, and often more stinging
Tretinoin	None	Prescription only

So a product with a lower percentage of a stronger form can do more than a higher percentage of a milder one. The number on the front only means something once you know which form it refers to.

The new European limit

Since April 2024 there has been a cap. Under Regulation (EU) 2024/996, retinol, retinyl acetate and retinyl palmitate are limited to 0.3 per cent in face products and 0.05 per cent in body lotions.

There is also a mandatory line on the packaging: "Contains vitamin A. Consider your daily intake before use." That is not about your skin but about your total vitamin A intake from food, supplements and skincare together.

The rule applies to new products since 1 November 2025, and everything on shelves has to comply by 1 May 2027. If you find a 1 per cent retinol face cream online, it was not made for the European market.

Worth knowing: 0.3 per cent is not a compromise. Most of the research showing real results works at or below that.

How to build it up

This is the whole game. A workable schedule:

Weeks 1 to 3: two evenings a week.
Weeks 4 to 6: every other evening, if your skin stays calm.
After that: nightly is possible, but four or five evenings a week suits many people better.

A few things that make the difference:

A pea-sized amount for the whole face. More does not work faster, it only irritates.
On dry skin. Damp skin absorbs more and stings more.
Try the sandwich. Moisturiser, then retinol, then moisturiser again. It slows absorption and takes the edge off, and you lose very little effect.
Skip the eye area and the corners of your nose in the first weeks, or go around them.

Is purging real?

Partly. Because retinol speeds up cell turnover, congestion that was already forming under the surface comes up sooner. That can mean more spots in the first weeks, usually in the places where you normally get them.

New spots in places you never get them are not purging. Neither is burning, swelling or peeling in sheets. That is irritation, and the answer is to go back a step in frequency.

What to combine it with, and what not

Good alongside: niacinamide and ceramides. Both support the barrier while retinol stimulates it, which is exactly what you need during the build-up phase.

Not in the same evening: exfoliating acids. AHA or BHA plus retinol on the same night is too much for most skin types. Alternate.

Not without: daily SPF. Retinol makes your skin more sensitive to UV, and sun damage undoes the thing you are using it for. The article on SPF covers how much you actually need.

Not during pregnancy. Topical vitamin A is generally advised against while pregnant or breastfeeding. Check with your midwife or doctor.

What ours is

Complexion Care is a night serum with retinol and retinyl palmitate together, alongside niacinamide and a peptide. The two forms mean it starts working while still building gently, and the niacinamide is there for the reason above: it keeps the barrier steady while the retinol does its work.

It goes on cleansed, dry skin in the evening, with Dewy Dream on top.

Frequently asked questions

How long before I see something?

Texture and clogged pores after about eight weeks. Fine lines and firmness take six months or more of consistent use. Retinol rewards patience more than almost anything else.

Can I use it if my skin is sensitive?

Often yes, if you start at once a week and use the sandwich method. If your barrier is currently damaged, repair that first.

Morning or evening?

Evening. Retinol breaks down in light, and your skin is more UV-sensitive while using it.

Do I have to stop in summer?

No, provided you wear SPF daily. If you are spending long days in strong sun, dropping the frequency for that period is reasonable.
