Retinol Serum

Retinol is a form of Vitamin A and a popular ingredient in skincare, known for its anti-aging effects. It promotes cell regeneration and collagen production, which can help reduce wrinkles and improve skin texture. Additionally, retinol has the ability to refine pores, reduce pigmentation, increase skin moisture, and accelerate scar healing.

For the first two weeks, apply one pump of the Retinol Serum every other evening. If your skin adapts well and shows no redness or flaking, you can begin using Retinol daily for the next 3 to 6 weeks. After this period, you may gradually increase the amount to up to three pumps per evening.

As of 2025, a new EU regulation prohibits the production and over-the-counter sale of skincare products containing retinol concentrations above 0.3%. Higher doses of retinol are now classified as prescription medications – a clear sign of just how powerful this active ingredient truly is.

We are already working intensively on new formulations that closely replicate the effects of our previous 0.5% and 1.0% Retinol Serums.

In the meantime, you can still achieve excellent anti-aging results with our Retinol 0.3% Serum by applying a slightly more generous amount (more product = locally higher concentration) and following with one of our high-performance night creams.

For your morning routine, we recommend pairing it with our Vitamin C + Biobotox Serum, which perfectly complements and enhances the effects of retinol.

A high-quality retinol serum is characterized by an effective concentration of retinol that is potent enough to deliver visible results while remaining gentle enough to avoid skin irritation. Additionally, it should contain moisturizing and soothing ingredients, such as vitamin E, to nourish the skin and minimize potential side effects like dryness or redness.

There is no fixed age for starting a retinol routine. If you struggle with blemished skin at a younger age, retinol can already be beneficial at that point.

From the age of 21, the skin naturally begins to lose collagen, elastin, and firmness each year. That’s why retinol becomes a targeted and effective anti-aging measure from this age onward – helping to prevent and reduce early signs of aging while strengthening the skin’s structure in the long term.

Retinol serum should be gradually integrated into the skincare routine, starting with application every other or every third evening to allow the skin to acclimate to the retinol. Apply after cleansing and before moisturizing. Gently massage a small amount of the serum onto the face, avoiding the eye area. Since retinol makes the skin more sensitive to sunlight, it is important to use a high SPF sunscreen in the morning. After a few weeks, the frequency of use can be increased if the skin responds well to the product.

Yes, retinol can be effective in helping with acne. It promotes cellular turnover, which helps prevent pore congestion, one of the main causes of acne. Retinol also has anti-inflammatory properties that can help reduce redness and swelling. It's important to start with a low concentration and gradually introduce it to the skin to avoid irritation. For severe acne or sensitive skin, it's recommended to consult a dermatologist before use.

By accelerating cell turnover, retinol supports the renewal of the upper skin layers, gradually improving the appearance of scars over time. It also stimulates collagen production, which enhances skin texture and elasticity.

For best results, retinol should be used consistently over an extended period.
It’s essential to apply sunscreen during the day while using retinol, as the skin becomes more sensitive to UV exposure.

Yes, you can use retinol during the summer - it's important to always apply a daytime moisturizer with high sun protection and blue light filter. Because the skin can become more sensitive to sunlight due to retinol. Monitor your skin closely, adjust your skincare routine to your individual needs, and if necessary, take a short break from retinol.

Retinol is generally well tolerated, but proper application is key. Important: It should be used only in the evening and introduced gradually to allow the skin to adjust.

The Optimal Way to Start Using Retinol:

• Week 1–2: Apply one pump of Retinol 0.3 every other evening to cleansed skin.
• From Week 3: If your skin adapts well and shows no redness or flaking, you can start using Retinol 0.3 every evening.
• Afterward: If your skin tolerates it well, you can gradually increase the amount to up to three pumps per evening.

Yes, incorrect application of Retinol can cause skin irritations in some individuals, such as redness, dryness, or flaking. Therefore, it is important to gradually introduce the skin to Retinol and apply it only in the evening. During the day, it is crucial to always use sunscreen with SPF 30, as Retinol can increase the skin's sensitivity to sunlight.

It is recommended to avoid retinol during pregnancy.

Patience is the key. For visible results, it is recommended to consistently apply Retinol for at least 2-3 months.

Absolutely – Retinol and Vitamin C are a true dream team for your skin. However, they should not be applied at the same time.

Here’s our recommendation:

Use the Vit C + Biobotox Serum in the morning – it protects against free radicals, brightens pigmentation spots, and reduces expression lines. In the evening, apply the Retinol Serum – it promotes cell renewal and helps reduce wrinkles, blemishes, and enlarged pores over time.

This way, your skin benefits from maximum efficacy – around the clock.

Retinol and Retinal both belong to the family of retinoids – some of the most effective active ingredients for targeting wrinkles, blemishes, and uneven skin tone.

Retinal (retinaldehyde) is the direct precursor of retinoic acid (also known as tretinoin), which is classified as a medicinal ingredient and therefore not permitted in over-the-counter cosmetics within the EU. Retinal acts more quickly than retinol, but it can be more irritating and often less stable in skincare formulations.

Retinol, by contrast, is considered the more established and better tolerated version. It is converted within the skin through two enzymatic steps into retinoic acid, delivering a gentle yet highly effective result.

This is why retinol is regarded as the gold standard in anti-aging skincare. When used in the right concentration and paired with other high-quality actives, retinol unleashes its full regenerative power.

Absolutely! Retinol works regardless of gender and is an excellent choice for men – especially those dealing with enlarged pores, blemishes, or deeper expression lines.

Men’s skin is typically thicker and produces more sebum, making it particularly responsive to retinol’s pore-refining, smoothing, and anti-inflammatory properties.

It’s also a great addition to any post-shaving routine, as it helps prevent clogged pores, ingrown hairs, and minor inflammation.

The same rules apply: use it in the evening, start gradually, and stay consistent – your skin will thank you with visible results.
