Retinol peel: why autumn and winter, why not summer — and why SPF isn't optional

Where the myth "you can have retinol treatments all year round" comes from

Some of this confusion comes from lumping different forms of retinol into a single category. Retinol in pharmacy creams, retinol in serums, prescription tretinoin and a professional retinol peel performed in a salon get treated as the same thing. In reality, there's a fundamental difference in quality between home-use concentrations and salon-strength ones. The second cause: home-care advice gets copied straight into the context of salon treatments, where concentrations, depth of action and skin response are on an entirely different scale.

On top of that, there's holiday-season pressure: we like to head into summer with good skin, we want quick results, the salon is nearby and has a free slot — so the appointment gets booked. The outcome? Skin fresh from an intensive retinol treatment, exposed to July sunshine. This isn't about bad intentions. It's about incomplete information.

Myth 1: "You can have a retinol peel in summer"

This isn't just a myth — it's one of the most common mistakes, and one that genuinely ends in a dermatological problem. Retinol speeds up cell turnover and shedding of the epidermis. The new skin that surfaces after the treatment is significantly thinner. It lacks the "usual" protective layer and is several times more sensitive to UV radiation than skin that's gone through a full natural renewal cycle.

Combine freshly peeled skin with summer sun, and you have a straightforward route to post-inflammatory hyperpigmentation. It can persist for months and often requires further treatment — sometimes, ironically, with retinol again. On top of that, heat, sweating and outdoor activity increase the risk of irritation in skin that's already in a state of recovery, even without the sun.

Myth 2: "There's no sun in winter, so SPF isn't necessary"

This is one of the most costly shortcuts in skincare thinking. UVA radiation — the type responsible for skin ageing and hyperpigmentation — passes through clouds and window glass, and doesn't disappear in winter. Its intensity is lower than in summer, but for skin recovering from a retinol treatment, "lower" still means "enough to cause harm."

We ask about SPF use in the salon not because it's a formality — but because without SPF, the results of a peel don't just diminish, they can reverse. Retinol works on new, freshly renewed skin. Without a filter, that same skin is exposed to the exact radiation that would set it right back to where it started.

Why autumn and winter are the optimal time

The autumn-winter season is structurally better for retinol peels for several reasons — and this isn't an excuse, it's physics and biology. First — less sun and fewer hours of UV exposure reduce the risk of hyperpigmentation almost automatically. Second — cooler air reduces sweating and irritation while the skin is recovering. Third — on grey, dry post-summer skin, the results of renewal are clearly visible: an even skin tone, better texture and improved hydration, noticeable a few weeks after a series of treatments.

1. 01

   October–November

   The ideal way into the season: skin needs recovery after summer, UV levels drop significantly, and you can start a series of treatments.

2. 02

   December–January

   Mid-season: the series is under way, skin is renewing itself; SPF is mandatory, even on cloudy days and near windows.

3. 03

   February–March

   Finishing up and locking in the results before the sunny season returns; a good time for hydrating and biostimulating treatments as a complement.

4. 04

   April–May

   A break, or planning the next series; skin ready for summer — but from now on SPF every day, not just at the beach.

This doesn't mean skin needs no care in summer — it does, just different procedures. Gentle enzyme peels, deep hydration, treatments that strengthen the skin barrier, and of course a consistent filter — that's the summer protocol that doesn't clash with the season. Retinol waits for autumn, and it's worth the wait.

Myth 3: "One course is enough for the whole summer"

A retinol peel doesn't "reset" the skin permanently — it's a regenerative treatment, and its results last for a period proportional to the depth of the treatment and the condition of your skin. Most people notice a clear improvement after a series of several treatments at seasonal intervals. But without UV protection for the rest of the year, these results simply fade. The sun breaks down collagen, generates free radicals and activates melanocytes — regardless of what you did in the salon three months earlier.

Hence the logic of a seasonal approach to peels — one series in autumn, possibly topped up in winter, protection and maintenance in spring. This isn't a scheme dreamed up by salons — it's a response to the skin's biological rhythm and the annual cycle of UV exposure. Treat a peel as a one-off course, then head back to summer holidays without a filter, and you're building on sand.

Myth 4: "A retinol peel is only for women with hyperpigmentation"

A retinol peel is often thought of as a niche procedure "for hyperpigmentation" — and that's a far too narrow view. Retinol stimulates collagen synthesis, speeds up cell renewal and evens out skin texture, which translates into many different indications. Hyperpigmentation is one of them, but the goal is just as often to smooth fine lines, improve the tone of grey, tired skin, or regulate sebum production in oily, acne-prone skin.

Indications for men can be somewhat different — thicker, more oily skin responds to retinol differently to women's skin. Redness and flaking can be stronger in the early stage of the series, but the results on texture and sebum regulation are often very noticeable. The season is the same for everyone: autumn and winter, always with SPF.

Myth 5: "Every retinol peel is the same"

"I'll just order retinol from the pharmacy — it's the same thing." No, it isn't. Concentration, chemical form and delivery vehicle of the active substance determine how deeply it works and how intense the skin's response is. In a salon retinol peel, the concentration and depth of action are on an entirely different level from OTC products. That's exactly why it requires a different aftercare protocol, proper skin preparation, and above all, a different level of care around sun protection.

The salon also assesses your skin's condition before the treatment — active rosacea, fresh inflammatory lesions, very dry skin, or a damaged skin barrier can be temporary contraindications. This isn't about scaremongering — it's simply about making sure the treatment actually delivers results rather than making a problem worse. That's why a series of treatments starts with a consultation, not with the first appointment.

How not to lose the results — rules that actually matter

A few weeks after a series of retinol peels, skin can look noticeably better: a more even tone, finer texture, less visible pigmentation, better response to hydration. To keep these results for as long as possible — and so that the next series starts from a better baseline rather than back at zero — a few rules genuinely matter.

• SPF 30–50+ every day — throughout the season after treatment, and ideally as a permanent part of year-round skincare. Even in December, even at a desk near a window.
• Avoid intense sun exposure for a minimum of 2–3 weeks after each treatment in the series.
• Moisturise the skin barrier — retinol speeds up shedding, so during this time the skin needs intensive hydration with ceramides and barrier-strengthening ingredients.
• Tell your specialist about any medications and products you're using — some photosensitising medications and acids in your home routine can affect the protocol.
• Don't combine with high-strength AHA/BHA at home in the weeks following a salon treatment — the skin is already doing its own work, it doesn't need extra exfoliation on top.

What to combine a retinol peel with — and what not to

A retinol peel fits well into a series of skin renewal treatments — precisely because it works deeper than gentler enzyme peels and prepares the skin to respond better to further procedures. We most often combine it with hydrating and biostimulating treatments, which fill in what retinol alone can't address: skin volume and density.

What not to combine at the same time: laser peels and deep exfoliating treatments in the same week — stacking stimulation this way is inversely proportional to the results, and the risk of irritation goes up. Series planning is discussed in detail during your consultation — so you don't stack too many stimuli at once, and every treatment has room to work.

When a retinol peel really works

A retinol peel works best as part of a planned series, in the right season, with consistent SPF protection — not as a one-off experiment. This approach takes some patience, but it gives results that are visible and lasting: skin that doesn't just look different straight after the treatment, but that genuinely starts to regenerate at a deeper level.

If you're wondering whether this is the right treatment for you — and when to start — the best step is a consultation. We assess your skin, plan the series, and answer every question before your first appointment. Yes, that includes the question about SPF in winter.
