Retinol for beginners: use and limits

What retinol is

Retinol belongs to the vitamin A substances, which are called retinoids. The German Federal Institute for Risk Assessment (BfR) describes vitamin A as a group of fat-soluble substances. According to the BfR, retinol and its esters are used in cosmetics mainly to reduce small wrinkles, and such products are often advertised as "anti-aging". This guide is about use. For the definition, the INCI names and tolerance, see the German-language entry Retinol.

A realistic view helps. Dr. Thomas Koppmann, project lead at Stiftung Warentest, says that retinol can improve the look of the skin and can have a temporary plumping effect, but that it cannot stop or reverse the natural ageing process. Think of retinol as one possible part of your routine, not as a way to stop time.

Getting started

Stiftung Warentest advises using retinol products slowly at first and watching the effect closely, because retinol can irritate the skin, especially at the beginning, and cause redness and dryness. It does not name a fixed schedule. A careful way to begin looks like this:

1. One new product at a time. If your skin reacts, you know which product to blame.
2. Slowly, then watch. Stiftung Warentest advises a slow start and close observation. Increase only if your skin stays calm.
3. Keep the rest simple. Change nothing else at the same time; how to read the label of such products is explained in How to read an INCI list in five steps.
4. Pause if your skin protests. If it turns red, burns or flakes strongly, leave the product out. If that does not settle, see a dermatologist.

If you have a skin condition such as neurodermatitis, rosacea or acne, discuss active ingredients with a dermatologist first. A cosmetics page cannot assess or treat these conditions.

Sun protection

The German Federal Office for Radiation Protection (BfS) recommends applying sunscreen generously to all uncovered skin half an hour before going out, with a sun protection factor of at least 30 and a filter against both UVA and UVB. Reapplying keeps the protection but does not extend it. The BfR names reapplying at least every two hours, especially after bathing and drying off. From UV index 3, seek shade around midday (BfS).

Whether retinol makes the skin more sensitive to light may be stated in the manufacturer's information; you can also ask a dermatologist. Regardless, sun protection applies to everyone. UV radiation can damage the skin lastingly and cause skin cancer, among other things (BfR). More on this: Sonnenschutz fürs Gesicht (German) and Understanding the UV index.

Common mistakes

• Too much too fast. Retinol can irritate, as described above. A slow start is the advice of Stiftung Warentest.
• Trusting the claim on the front. According to Stiftung Warentest, the Chemical and Veterinary Investigation Office in Karlsruhe found too little vitamin A for an anti-aging effect in about a third of 70 face creams. The further back an ingredient stands on the list, the lower its concentration.
• Ignoring your total vitamin A intake. This is why the warning on the pack exists. See the next section.

EU limits and the warning on the pack

The EU's Scientific Committee on Consumer Safety (SCCS) considers vitamin A in cosmetics safe at up to 0.05 percent retinol equivalent in body lotion and up to 0.3 percent retinol equivalent in other leave-on and rinse-off products (opinion SCCS/1639/21, 2022). Commission Regulation (EU) 2024/996 of 3 April 2024 sets the same limits in Annex III. For products containing retinol, retinyl acetate or retinyl palmitate it also makes a label obligatory: "Contains Vitamin A. Consider your daily intake before use".

The regulation sets two dates. From 1 November 2025, products that do not meet the conditions may no longer be placed on the Union market. From 1 May 2027, they may no longer be made available on it. Older products can therefore still be in shops and bathroom cabinets for a while.

Why the reference to daily intake? You take in vitamin A mainly through food, including fortified food and supplements. The German Nutrition Society recommends about 1 milligram of retinol equivalents a day for adults, which a balanced diet usually covers (as reported by the BfR). The BfR names 3 milligrams as the amount considered safe for daily long-term intake from all sources. For women after the menopause, the Scientific Committee on Food recommended at most 1.5 milligrams, because of a possible link with bone density; the BfR calls the data on this inconsistent. Talk to your doctor about vitamin A supplements as a precaution.

Pregnancy and breastfeeding: ask first

The BfR writes that high doses of vitamin A caused harm to the unborn young in animal experiments, and considers such effects through cosmetic products unlikely. Even so, talk to your doctor before you use retinol products during pregnancy or breastfeeding, and likewise if you are planning a pregnancy. The same applies to vitamin A supplements.

When to see a doctor

See a dermatologist if your skin does not settle after you stop the product, if it weeps, burns badly or swells, if you have a skin condition, or if you notice a skin change that keeps changing. The German Dermatological Society offers a search for dermatologists (in German).
