Retinol without irritation — how to start (and how retinal and bakuchiol differ)
A proven plan for introducing retinol into your skincare — without redness, peeling, and giving up after a week — plus an honest comparison with retinal and bakuchiol, so you can choose wisely.
Retinol has an almost unique status in cosmetology — it is one of the few ingredients whose effects are well documented and repeatable: it accelerates skin renewal, smooths, evens out skin tone, and supports collagen production. The problem is that most people experience it from the wrong side — irritation, burning, and peeling after the third use — and at this stage, they give up before their skin has a chance to adjust. We explain how to introduce retinol so that you can actually benefit from it, how it differs from retinal and bakuchiol, and for whom and when it makes sense to use it.
Retinization: how to acclimate your skin to retinol step by step
Retinization is nothing more than gradually acclimating the skin to retinol — a process that gives it time to develop tolerance before we reach for a higher frequency or stronger concentration. Skin that receives retinol too quickly and too often responds with inflammation: redness, dryness, a feeling of tightness, sometimes minor peeling. This does not mean that retinol is "not for it" — it most often means that the introduction process was too abrupt.
A good scheme looks something like this: in the first two to three weeks, retinol is applied 1–2 times a week, only in the evening, observing the skin's reaction for the next day. If there is no excessive irritation, the frequency is gradually increased — to every other day, and ultimately, after several to a dozen weeks, even to daily evening use. The key word is "gradually" — there is no need to rush this process, as the effects of retinol are spread over time, and skipping stages usually ends with a break forced by irritation, which is a step backward.
It is also worth remembering that retinization is an individual process. Dry and sensitive skin may need even six to eight weeks at the stage of 1–2 times a week before moving on. Oily and resilient skin often tolerates a faster pace. There is no one universal calendar here — there is, however, one universal rule: observing the skin is more important than a plan on paper.
Less is more — a principle that protects the skin
The most common mistake is not using retinol too frequently, but using it in too large an amount. The retinol product is applied in a thin layer — a pea-sized amount is enough for the entire face. Excess will not speed up the effect, but will increase the risk of irritation, as the skin receives more active substance at once than it can reasonably process.
The second tool that realistically reduces the risk of irritation is buffering — that is, applying retinol to skin that has been previously moisturized with cream, or mixing it with a moisturizing cream directly in the hand before application. Such a "buffer" slightly dilutes the contact of retinol with the skin and softens its action in the first weeks, without taking away its effectiveness — it simply slows down the rate at which the skin comes into contact with it. This is a technique worth using especially during the first contact with retinol or when transitioning to a higher concentration.
If redness, a feeling of tightness, or peeling occurs despite this, it is a signal to take a step back — use it less frequently, apply it thinner, with more buffering — and not to give up retinol altogether. Skin that has gone through this process consciously usually accepts retinol without any discomfort after a few weeks.
What not to combine with retinol — and why SPF in the morning is mandatory
Retinol is an evening ingredient — it is used in the nighttime routine, never in the morning. Partly because some forms of retinol lose stability under sunlight, and partly because skin working at night on renewal is less exposed to additional external stimuli at that time.
That same evening, it is advisable to avoid combining retinol with strong exfoliating acids (AHA, BHA in higher concentrations) and with vitamin C in low pH forms. Retinol and strong acids work at a similar level — they accelerate skin renewal — so when used together, they accumulate the risk of irritation instead of complementing each other. A sensible model is to separate them in time: for example, acids one evening, retinol the next, or acids in the morning (with SPF protection), retinol in the evening — never one on top of the other on the same day.
What is mandatory with retinol — without exceptions — is SPF filter during the day. Retinol accelerates skin renewal, which means a thinner protective layer and higher skin sensitivity to UV radiation. Skipping SPF while using retinol not only increases the risk of pigmentation but can also erase the effects that the skin has been working on all night.
Retinol does not forgive haste, but rewards patience — it is an ingredient for those who think about their skin in terms of weeks, not days.
Words of the cosmetologist J'ADORERetinol, retinal, and bakuchiol — how do they differ
All three ingredients are often advertised as "stronger" or "gentler" alternatives to each other, but in practice, they differ in mechanism and how much work the skin has to do to benefit from them. Retinol is a retinol alcohol — before it works, the skin must convert it in two stages to retinoic acid, the active form. Retinal (retinaldehyde) is one step closer to the active form, so it usually works faster and more intensely than retinol at the same concentration, although it can also be felt as stronger on first contact. Bakuchiol is not a retinoid — it is a plant-derived ingredient, a derivative of babchi, which mimics some of the effects of retinol through its influence on gene expression in the skin. Individual clinical studies show comparable effectiveness with better tolerance, but the evidence base for bakuchiol is still significantly smaller and less uniform than decades of research on retinol — it is a promising ingredient, but so far less studied.
| Feature | Retinol | Retinal (retinaldehyde) | Bakuchiol |
|---|---|---|---|
| Mechanism | Requires two transformations to the active form | One transformation closer to the active form | Not a retinoid — different action pathway |
| Effect speed | Moderate, spread over weeks | Usually faster than retinol | Comparable in individual studies, with regular use over several weeks |
| Skin tolerance | Requires retinization | Usually requires it to a similar extent | Generally better tolerated from the start |
| Photostability | Use in the evening | Use in the evening | More stable, but SPF in the morning is still mandatory |
| Pregnancy / breastfeeding | Consult with a doctor | Consult with a doctor | More often indicated as an option to consider — always after consultation |
None of these three ingredients is universally "better" — it depends on the point at which the skin is. Retinal is often chosen when a faster effect is desired and the skin already knows retinoids. Bakuchiol works where retinoids are not an option at all, or where the skin has previously reacted poorly to them. It is also worth remembering to distinguish between brands: the nanosome technology that some Sesderma and Mediderma products are equipped with is a method described by the manufacturers for delivering and stabilizing retinol in the formula — it should not be confused with solutions from other cosmetic brands that use different technologies and nomenclature.
Remember one thing
Retinol in the evening, SPF in the morning, thin layer, gradual pace — these are the four rules that practically determine whether the skin will "like" retinol or reject it. The rest is a matter of choosing the concentration and form for the stage the skin is currently at.
Who is retinol for and when to start
Retinol and its derivatives have a wide range of applications, but they are not an ingredient "for everything for everyone" — they make the most sense where the skin has a specific task to perform:
- anti-aging care — reducing wrinkles, improving firmness, supporting collagen production (usually from the mid to late twenties, as prevention, not just when visible wrinkles appear),
- pigmentation and uneven skin tone — accelerated skin renewal helps to reduce existing pigmentation and even out skin tone,
- acne and skin prone to blackheads — retinoids regulate exfoliation in hair follicles, reducing the tendency to clog pores (in such cases, the choice of form and concentration should always be consulted with a cosmetologist or dermatologist, as acne-prone skin can be more reactive),
- mature skin after regenerative treatments — as part of home care supporting the effects of treatments in the office.
Retinol is not recommended during pregnancy and breastfeeding — in these situations, we definitely advise against self-introducing retinoids and direct to consultation with the attending physician, who will assess whether and what form of care is safe. This is one of the few rules in cosmetology that has no good exceptions "on your own".

Common mistakes when introducing retinol
“Too strong, too fast”
The most common cause of failure with retinol is skipping the retinization stage — daily use from the first week or immediately a higher concentration "for a better effect". The skin responds with irritation, which can easily be mistaken for an allergy or intolerance, although in reality, it is simply the effect of too fast a pace.
“SPF in the morning is not that important”
Skipping sun protection during the day is a mistake that can negate the entire purpose of using retinol — the skin becomes more sensitive to UV, and without a filter, it risks deepening pigmentation instead of reducing it.
“I stop after a week because it’s peeling”
Light peeling in the first weeks is often a natural stage of adaptation, not a reason to give up. The solution is usually to reduce the frequency and add buffering, not to completely abandon retinol.
“I combine everything at once”
Applying retinol together with strong acids or vitamin C in acidic formulas on the same evening is a straightforward path to irritation. Separating active ingredients in time gives the skin a chance for calm regeneration.
Frequently asked questions
How to start using retinol to avoid irritation?
Start with a low frequency — 1–2 times a week, in the evening, in a thin layer, preferably with buffering using a moisturizing cream. The frequency is gradually increased only when the skin does not react with irritation at the current stage.
How does retinal differ from retinol?
Retinal (retinaldehyde) is closer to the active form of vitamin A than retinol, which is why it usually works faster and more intensely at a similar concentration. However, it requires similarly careful introduction as retinol.
Is bakuchiol a “natural retinol”?
Not exactly — bakuchiol is not a retinoid and works through a different mechanism, although it mimics some of the effects of retinol. It is often better tolerated, and individual studies show comparable effectiveness, but there is still significantly less scientific evidence than for retinol or retinal.
Can I use retinol during pregnancy or breastfeeding?
We do not recommend self-administering retinoids during pregnancy or breastfeeding. This is a decision that should be consulted with the attending physician — they will assess what form of care will be safe during this time.
How long does retinization take and when will I see results?
The process of acclimating the skin usually takes several to a dozen weeks, depending on its sensitivity. The first effects (improvement in smoothness, skin tone) may be visible after a few weeks of regular use, and a fuller picture after several months of consistent care.
