1% Retinol Booster

The 1% Retinol Booster uses encapsulated retinol and focuses specifically on more pronounced signs of ageing such as wrinkles and pigment spots.
The Vitamin A Serum combines three forms of vitamin A with bakuchiol and is aimed at first signs of ageing as well as blemish-prone skin.
The 1% Booster is therefore particularly suited to those experienced with retinol, while the Vitamin A Serum offers a more versatile introduction to vitamin A care.

Used regularly and at the right dosage, the 1% Retinol Booster can reduce the appearance of wrinkles and pigment spots and contribute to improved skin elasticity. These effects were confirmed in a 12-week clinical study. In addition, 83% of participants reported that the product makes their skin look smoother.**

*Measured instrumentally: wrinkle volume, skin elasticity and skin colouring. **Participant survey. Clinical in-use study with 30 participants over 12 weeks.

How quickly changes in the skin become visible can vary from person to person.
In our clinical study, a lower wrinkle volume, lighter pigment spots and improved skin elasticity were measured after 12 weeks of regular use. Consistent use in line with the application advice is particularly important here.

With sensitive skin, retinol should be introduced into your routine especially slowly and carefully. Start with a maximum of one application per week and mix no more than one pump, as recommended, at a ratio of 1:3 with a moisturiser without vitamin A. Do a patch test before the first application.

For sensitive skin, a moisturising and barrier-strengthening base routine is also particularly important to support the skin while using active ingredients. If signs of irritation appear, pause the application.

Yes, provided you introduce it gently, with no more than one application per week. Do a patch test before the first application and mix a maximum of one pump of the 1% Retinol Booster with a moisturiser without vitamin A at a ratio of 1:3. Sufficient moisturising care and barrier-strengthening products will support your skin during the adjustment phase. During the day we recommend sun protection with at least SPF 30. For a gentler start with vitamin A care, our Vitamin A Serum or the Night Cream with 0.05% retinol are good alternatives.

Cleanse your face as usual in the evening. Then mix one pump of the 1% Retinol Booster with your favourite moisturiser (without vitamin A) at a ratio of 1:3 and apply. Make sure to shake the booster before use. It is important to introduce the booster into your routine slowly at first, as your skin needs to get used to the new active ingredient. We recommend starting with one application per week. You can increase this gradually until you use the product regularly – we recommend a maximum of 2 to 3 times a week. If signs of irritation appear, pause the application for a few days and support your skin with soothing products.

For direct layering with the 1% Retinol Booster or using it on the same day, you can use any products that meet your personal skincare needs, as long as they do not also contain retinoids, exfoliating acids (AHAs & BHA), or Vitamin C. You don’t need to avoid these ingredients altogether—they should just be used on different days within your weekly skincare routine. The 1% Retinol Booster should be applied together with your favorite moisturizer. Simply mix one pump of the 1% Retinol Booster with your cream (without Vitamin A) in a 1:3 ratio on your hand.

No. Our Night Cream also contains retinol (0.05%). To avoid combining several retinoid products, we recommend using the 1% Retinol Booster exclusively with a moisturiser that does not contain vitamin A.

You should not use the product if your skin is irritated or badly sunburnt, or if you have skin conditions such as eczema or rosacea. During pregnancy or breastfeeding you should also avoid using retinol for safety reasons. Acids or irritating ingredients such as vitamin C or AHA/BHA can cause skin irritation when combined with retinol. Retinol should also be used exclusively in your evening routine. During the day we recommend sun protection with at least SPF 30.

If signs of irritation appear, pause the application for the time being. Soothing, moisturising and barrier-strengthening care can support your skin during this period. Only start using it again once your skin has calmed down, and reduce the frequency at first. Alternatively, you can switch to lower-dosed vitamin A products such as our Vitamin A Serum with 0.3% vitamin A derivatives or the Night Cream with 0.05% retinol.

When developing our products we comply with the applicable legal requirements for cosmetic products. These include, for example, rules on which substances may not be used in cosmetics at all, or only under certain conditions. Beyond that, we make deliberate choices when selecting our ingredients: we opt for fragrance-free formulations, for instance, and use exclusively vegan ingredients.

You can check which ingredients a specific product contains at any time in the full INCI list on the product page.

Yes. All ingredients are vegan – we do not use any animal-derived raw materials.

For safety reasons, people who are pregnant or breastfeeding should avoid products containing retinoids. Our Polypeptide Booster is an ideal alternative for your anti-ageing routine. You will find an overview of further products to avoid during pregnancy and breastfeeding here.

To avoid irritation, we recommend spacing out the use of vitamin C, BHA, AHA and niacinamide – morning and evening, or on different days. The 1% Retinol Booster should be introduced into your routine slowly. Using it too frequently, or combining it with other intensive actives at the same time, can irritate the skin. A well-matched routine supports tolerability and contributes to a smoother, more even-looking complexion.
