Retinol can do a lot for fine lines, uneven texture, pigment spots and blemished skin, but it's also an ingredient that makes the skin work more actively. That's why the question “is retinol safe?” is entirely relevant to ask before you begin.
For most people, retinol is safe when it's introduced gradually, used in a suitable strength and combined with good sun-protection habits. Incorrect or overly intensive use can, on the other hand, lead to an irritated, sore and dry skin barrier.
What is retinol, and why does the skin react?
Retinol is a form of vitamin A and belongs to the group of retinoids. In the skin, retinol is gradually converted into retinoic acid, which affects the renewal of skin cells. Over time, it can contribute to a more even skin surface, less visible fine lines and a clearer skin tone.
The results don't come from one day to the next. Retinol works by affecting processes in the skin, and that's precisely why the skin can react in the beginning.
Dryness, flaking, redness and a slight stinging sensation are common signs that the skin is trying to get used to the ingredient. Some can also experience more breakouts in the first weeks, especially if the skin easily gets clogged pores.
A reaction doesn't necessarily mean the product is wrong for you. Often it means that the amount, the frequency or the combination with other active ingredients is too demanding.
If you experience clear stinging, persistent redness, eczema or cracks in the skin, you should take a break.
Is retinol safe for everyone?
For healthy adults with normal or slightly sensitive skin, retinol is usually safe in cosmetic concentrations when it's introduced carefully.
There are, however, situations where it's better to wait, choose a milder solution or consult a doctor or dermatologist.
During pregnancy, it's recommended to avoid retinol and other retinoids as a precautionary principle. When breastfeeding, you should follow the recommendations for the specific product and possibly consult healthcare professionals. If you want a simpler alternative during this period, ingredients like niacinamide, hyaluronic acid or vitamin C can be relevant, if the skin tolerates them.
If you have rosacea, active eczema, very reactive skin or a damaged skin barrier, retinol may be too irritating right now.
The same applies if you use prescription retinoids or medical treatment for acne. You shouldn't just add a cosmetic retinol product on top of the existing treatment without professional guidance.
Retinol also shouldn't be used on sunburned, freshly shaved, cracked or recently heavily exfoliated skin.
The skin first needs calm and moisture. It's far easier to achieve good results when the skin barrier is stable than if you try to push an active treatment through on already irritated skin.
How to start safely with retinol
The safest start is rarely the fastest.
Choose a product with low to moderate strength, and use only a small amount – about the size of a pea – for the whole face.
In the beginning, avoid the eyelids, the area very close to the lips and the skin folds by the nose, since these areas often react first.
Start, for example, with one evening a week for the first two weeks.
If the skin feels normal, you can increase to two evenings a week. After a few more weeks, you can possibly move to every other evening.
Many achieve good results with this frequency and don't need to use retinol every evening.
More isn't necessarily better, especially when the goal is even, healthy skin over the longer term.
Apply retinol to completely dry skin. Feel free to wait a few minutes after cleansing, since damp skin can make the ingredient absorb faster and thereby feel more intense.
Finish with a simple moisturizer.
If the skin is sensitive, you can use moisturizer both before and after retinol. This method is often called the sandwich method and can make the adjustment considerably milder.
A simple evening routine can, for example, consist of cleansing, moisturizer, retinol and possibly another thin layer of moisturizer.
You don't need an advanced routine to get good results. Patience and consistency matter more than many different products.
Ingredients you should use thoughtfully
Retinol works best when the rest of the skincare routine doesn't overload the skin.
That doesn't mean you can never use other active ingredients, but timing and the skin's tolerance are decisive.
Preferably avoid strong AHA or BHA acids, exfoliating scrubs and retinol in the same evening routine, especially while the skin is getting used to retinol.
The combination can immediately give a smoother feeling, but at the same time increases the risk of irritation, dryness and flaking.
Use acid on a different evening instead, or wait until the skin has gotten well used to retinol.
Benzoyl peroxide can also be drying in combination with retinol. If you use both against acne, it can be gentler to use benzoyl peroxide in the morning or on separate days.
Vitamin C also doesn't need to be applied at the same time as retinol. Many prefer vitamin C in the morning and retinol in the evening, among other things because it makes the routine simpler.
Soothing and moisturizing ingredients, on the other hand, are good companions.
Ceramides, glycerin, hyaluronic acid, squalane and niacinamide can support the skin barrier and make it easier to use retinol over time.
Sunscreen is part of the retinol routine
When you use retinol, sunscreen should be a fixed part of the morning routine.
Retinol doesn't necessarily make the skin permanently thinner, but skin that's in an active adjustment phase can be more sensitive and have less tolerance to sun exposure.
UV radiation can also worsen pigment spots and counteract some of the results you're trying to achieve with skincare.
Choose SPF 30 or higher, and use a sufficient amount on the face and neck.
If you spend a lot of time outdoors, sun protection should be reapplied as needed.
This applies all year – also on overcast and cold days.
Regular sun protection is one of the most important things you can do to preserve an even and fresh skin tone.
Retinol and home-based beauty technology
If you use LED light, microcurrent or other devices for home treatment, it's a good idea to be extra attentive to the skin's reaction when retinol is also part of the routine.
A mild LED routine is often tolerated fine, but if the skin is already red, flaking or stinging because of retinol, you should prioritize rest and moisture over more active treatments.
Microcurrent is normally used on clean skin together with a suitable conductive serum or gel.
Retinol isn't meant to work as a contact product under a microcurrent device.
So use the technology and retinol in separate steps or at different times, and always follow the instructions for the device you're using.
After more intensive home treatments, it can be sensible to wait with retinol until the skin feels completely normal again.
At AvelineCare, home treatments are about making good routines accessible – not about doing as much as possible in one evening.
The skin usually responds better to a calm and regular plan than to many strong treatments at the same time.
Signs that you should scale back
A little dryness in the beginning can be expected, but the skin shouldn't feel constantly sore or irritated.
Take a break or reduce the frequency if you experience strong stinging, itching, swelling, clear redness that doesn't go away, cracks in the skin or crusting.
Temporarily switch to a mild cleanser and a simple, fragrance-free moisturizer until the skin has calmed down.
When the skin feels stable again, you can possibly try retinol again with longer intervals and more moisturizer.
If the same reaction comes back, the product, the strength or the timing is probably not right for your skin.
In case of a strong reaction, rash or uncertainty about a skin condition, you should contact a doctor or dermatologist.
Retinol can be a safe and effective supplement to skincare, but the ingredient rewards a cautious approach.
Give the skin time, protect it from the sun, and adjust the pace according to how the skin actually feels – not according to how quickly you hope to see results.
