Retinol: everything you need to know before you start
Retinol is one of the most discussed ingredients in skincare — and for good reason. It stimulates cell renewal, supports collagen production, and can help reduce fine lines, hyperpigmentation, and uneven skin texture. But retinol also requires the right approach: starting too quickly or dosing too high can lead to irritation. In this article, we explain how retinol works, how to start using it, and which products we offer.
In short:
• Retinol (vitamin A) stimulates cell renewal and collagen production
• Always start with a low concentration and gradually build up
• Use retinol only in the evening and always combine with SPF during the day
• Not suitable during pregnancy and breastfeeding

What is retinol?
Retinol is a form of vitamin A — a fat-soluble vitamin naturally found in food and essential for skin health. In skincare, retinol is used for its ability to penetrate deep into the skin and stimulate processes that slow down with age.
When you apply retinol to your skin, enzymes in the skin convert it into retinoic acid. This is the active form that actually has an effect on skin cells. The difference with prescription retinoic acid (tretinoin) is that retinol works more gently because the conversion happens gradually. This makes it more suitable for home use.
There are different forms of vitamin A available in skincare. Retinol is the most potent form available without a prescription. Retinyl palmitate and retinyl acetate are milder variants. Retinal (retinaldehyde) falls between retinol and retinoic acid in terms of efficacy.
What does retinol do for your skin?
Stimulates cell renewal
Your skin continuously renews itself: new cells are created in the lower layers and gradually move to the surface. As you age, this process slows down. Retinol accelerates cell renewal, causing old, damaged skin cells to be replaced faster by new ones. The result is a more even, fresher skin texture.
Supports collagen production
Collagen is the protein that keeps your skin firm and elastic. From your mid-twenties, natural collagen production decreases — by approximately 1% per year. Retinol can help slow down this process by supporting collagen production and simultaneously inhibiting the breakdown of existing collagen.
Reduces fine lines and wrinkles
Through the combination of accelerated cell renewal and collagen support, consistent use of retinol can help reduce fine lines and superficial wrinkles. Deep wrinkles will not completely disappear, but skin texture can visibly improve.
Evens out skin tone
Retinol helps reduce hyperpigmentation by accelerating cell renewal. Pigmented skin cells are shed faster and replaced by new, more even skin. In combination with vitamin C and SPF, this is an effective approach for uneven skin tone.
Helps with blemishes
Retinol can help regulate sebum production and prevent dead skin cells from clogging pores. This also makes it a valuable ingredient for blemish-prone skin — provided it is introduced slowly.
Did you know? Jan Marini Age Intervention Retinol Plus contains 0.5% all-trans-retinol, combined with hydrating and soothing ingredients. This delivers powerful results with minimal irritation.
How do you start using retinol?
The most important rule with retinol is: build up slowly. Your skin needs to get used to the ingredient. If you start too quickly or with too high a concentration, your skin may react with dryness, redness, flaking, or a tight feeling — the so-called 'retinol purge'.
Week 1-2: Apply retinol every other evening to clean, dry skin. On alternate evenings, use a repairing night cream without retinol.
Week 3-4: If your skin shows no irritation, increase to every evening.
After 4 weeks: You can gradually increase to a higher concentration or twice daily, depending on your skin's tolerance. If irritation occurs: reduce the frequency and allow your skin to recover.
Always combine with SPF: Retinol makes the skin more sensitive to UV radiation. Daily sun protection with at least SPF 30 is mandatory when using retinol.

ASAP collection

Combining retinol with other ingredients
Retinol + niacinamide: a strong combination. Niacinamide strengthens the skin barrier and can reduce the chance of irritation from retinol. You can apply them one after the other in the same evening routine.
Retinol + hyaluronic acid: hyaluronic acid hydrates and helps keep the skin supple. Ideal to apply after retinol for extra comfort.
Retinol + vitamin C: both are powerful active ingredients. Preferably use them at different times: vitamin C during the day, retinol in the evening.
Retinol + AHA/BHA: be careful with this combination. Both exfoliate the skin and together they can cause irritation. Use them on alternating evenings, not on the same evening.
Retinol + SPF: not optional but mandatory. Retinol makes the skin more sensitive to UV radiation. Always use at least SPF 30 during the day.
Common mistakes with retinol
Starting too quickly with a high concentration. Always start low and build up. Your skin needs to get used to retinol — this takes two to four weeks.
Using retinol during the day. Retinol breaks down under the influence of UV light and makes the skin more sensitive. Always use it in the evening.
Skipping SPF. Without sun protection, retinol use is not only less effective, but it can also lead to additional skin damage due to UV sensitivity.
Stopping at the first sign of flaking. Slight flaking or dryness in the first few weeks is normal — it's a sign that cell renewal is accelerating. Reduce the frequency if it becomes uncomfortable, but don't stop immediately.
Combining retinol with too many other active ingredients. Retinol, AHA, BHA, and vitamin C on the same evening is too much for most skin types. Keep it simple: retinol + niacinamide + moisturizer is an effective evening combination.
Frequently asked questions about retinol
When will I start to see results?
Skin texture can improve after four to six weeks. For a visible reduction in fine lines and hyperpigmentation, three to six months of consistent use is realistic.
Can I use retinol if I have sensitive skin?
Yes, but with extra caution. Start with a low concentration, use it a maximum of twice a week, and combine it with a repairing night cream. If irritation persists: pause and consult a skin professional.
Can I use retinol during pregnancy?
No. The use of retinol and other forms of vitamin A is not recommended during pregnancy and breastfeeding. Consult your midwife or doctor for alternatives.
What is the difference between retinol and tretinoin?
Tretinoin (retinoic acid) is the active form of vitamin A and is only available by prescription. Retinol is converted into retinoic acid in the skin and therefore works more gradually and gently. Jan Marini Age Intervention Retinol Plus contains 0.5% all-trans-retinol — comparable to 0.05% tretinoin in terms of effectiveness, but with less irritation.
Can I use retinol all year round?
Yes, provided you use SPF daily. In the summer, some people choose to reduce the frequency slightly or use a milder form. Stopping is not necessary if you protect your skin well.
