Retinol Serum

A retinol serum supports skin cell renewal and can help smooth fine lines and wrinkles, even out pigmentation, minimize pores, and combat blemishes. With regular use, the skin can appear smoother, more even, and fresher overall.

Among dermatologists, retinol is considered one of the most thoroughly researched and effective active ingredients in skincare. It is often recommended to specifically target signs of aging, pigmentation issues, and blemishes—provided it is used in the correct dosage and applied properly.

The first changes in skin texture may become visible after about 4–6 weeks. More noticeable effects, such as improvements in wrinkles or age spots, typically appear after at least 8–12 weeks of consistent use. Retinol works gradually and over the long term; it does not work overnight.

A retinol serum can be beneficial as early as your mid-20s to help prevent premature signs of aging. As you get older, retinol is often used specifically to address existing wrinkles, age spots, and a loss of skin elasticity.

Dermatologists recommend retinol serums that are formulated to be stable, have a precise concentration, and are well-tolerated. It is crucial that the retinol serum matches your skin type and your previous experience with retinol—ranging from low-dose products for beginners to high-dose variants. In a comprehensive retinol comparison test, which was featured on programs such as “taff” and “SAT.1 Frühstücksfernsehen,” dermatologist Dr. Pamela Mai provided expert guidance throughout the test. In this context, the DOC BERGER EFFECT Retinol Serum was compared to a drugstore retinol serum. Over the course of the test, DOC BERGER EFFECT Retinol demonstrated measurable improvements in skin texture, including a reduction in wrinkle depth. The well-thought-out, cleanly formulated composition and the retinol serum’s good tolerability were also highlighted.

Yes, retinol serum can also be suitable for sensitive skin, provided it’s low-concentration, free of harsh ingredients, and introduced gradually into your skincare routine. DOC BERGER EFFECT’s Retinol Sensitive, which contains bakuchiol and novoretin, is particularly well-suited for a gentle introduction.

No. Retinol does not make the skin thinner. On the contrary: With long-term use, retinol can strengthen the skin's structure and thicken the skin by promoting collagen production. 

Whether a retinol serum can be used daily depends on its concentration, formulation, and how well your skin tolerates it. Many users start by applying it once or twice a week and gradually increase their usage until it becomes part of their regular daily evening routine.

Yes, a retinol serum can also be used in the summer. However, it’s important to consistently use sunscreen during the day, as retinol can make the skin more sensitive to light. A high SPF should be a regular part of your skincare routine.

Yes—absolutely! Retinol is effective regardless of gender and is also ideal for men, who often suffer from large pores, blemishes, or deep expression lines. Since men’s skin is generally thicker and produces more sebum, it benefits particularly from the pore-refining, smoothing, and anti-inflammatory effects of a retinol serum.

It’s also an ideal addition to your shaving routine, as it helps prevent clogged pores, ingrown hairs, and minor inflammation. 

Yes, definitely! Retinol and vitamin C are a real dream team for your skin—but don't use them at the same time.

Our recommendation: Use the Vitamin C + Biobotox Serum in the morning—it protects against free radicals, lightens dark spots, and reduces expression lines. In the evening, use the Retinol Serum—it supports cell renewal and provides long-term benefits against wrinkles, blemishes, and large pores. This way, your skin benefits from maximum effectiveness around the clock.

Retinol and retinal both belong to the retinoid family, which includes some of the most effective active ingredients for combating wrinkles, blemishes, and an uneven complexion. Retinal (retinaldehyde) is the direct precursor to retinoic acid—which is not permitted in cosmetic products in the EU because it is classified as a pharmaceutical. Although retinal acts faster than retinol, it can be more irritating and is often less stable in cosmetic formulations. Retinol, on the other hand, is considered the more proven and better-tolerated option. It is converted into retinoic acid in the skin through two enzymatic steps, resulting in a gentle yet effective action. Retinol is therefore considered the gold standard in anti-aging skincare.

A new EU regulation has been in effect since 2025, under which retinol concentrations exceeding 0.3% may no longer be freely manufactured or sold. Since then, higher-dose retinol has been classified as a prescription drug. This regulatory change underscores once again just how effective retinol actually is as an active ingredient.

With this in mind, we have worked intensively on new formulations that come as close as possible to the effects of our existing 0.5% and 1.0% retinol serums—while offering improved tolerability and maximum safety. The result is two newly developed retinol serums:

Retinol Sensitive is similar in purpose to our previous Retinol 0.3% Serum, but it has a gentler formula and is better suited for beginners or those with more sensitive skin.

Retinol Intense is designed as a counterpart to the earlier Retinol 0.5% and 1.0% formulations. In this product, we combine the maximum permitted concentration of pure retinol with other retinoids and plant-based, retinol-like active ingredients to specifically intensify the skin-renewing effect.

This is how we ensure highly effective, modern retinol skincare even under the new regulatory framework—tailored, well-thought-out, and designed to meet a variety of skin needs.

No. Retinol and other vitamin A derivatives should be avoided during pregnancy and while breastfeeding. During this time, alternative, non-retinoid active ingredients are recommended. If you have any questions, you should always consult a healthcare professional.
