Retinol Intense

The strongest over-the-counter retinol available in the EU contains 0.3% pure retinol. High-dose formulations combine this concentration with additional retinoid forms to further enhance anti-aging performance. Such products are designed for skin already accustomed to retinol and seeking intensified results. Lower concentrations are more suitable for beginners or sensitive skin.

The optimal retinol concentration depends on skin condition and retinoid experience.

• Beginners: 0.01–0.1% retinol
• Advanced users: up to 0.3% retinol

More important than the percentage alone is a balanced formulation with soothing and barrier-supporting ingredients, along with modern retinoid boosters.

Retinol is considered the gold standard among anti-aging ingredients. Clinical studies demonstrate that retinoids stimulate collagen synthesis, accelerate cell turnover, and measurably reduce photo-induced skin aging. Few cosmetic ingredients are as comprehensively supported by scientific evidence in their anti-aging efficacy.

Yes, if your skin is already accustomed to retinol and tolerates it well. However, introduction should always be gradual. Once the skin has adapted, high-dose retinol can often be used nightly.

This strongly depends on skin condition and proper usage. For many beginners, 0.3% retinol can initially be quite intensive. Therefore, we recommend starting with lower concentrations (approximately 0.01–0.1% retinol) to allow the skin to gradually adapt. Our Retinol Sensitive is ideal for this purpose. With slow progression, supportive skincare, and consistent sun protection, 0.3% retinol can later be very well tolerated. The decisive factor is not merely the percentage, but how prepared the skin is and how carefully usage is increased.

Our Retinol Intense with 0.3% retinol, combined with additional retinoid derivatives, can deliver highly intensive effects comparable to previously common higher percentage formulations (0.5% or 1% retinol). The key factor is not just the percentage, but the entire retinoid system, including stability and tolerability.

Retinol improves skin structure long-term (including enlarged pores and pigmentation) and supports collagen production. Hyaluronic acid provides intense hydration and can temporarily plump fine lines. The combination is ideal: retinol works on structure, hyaluronic acid on hydration and suppleness. Actives such as HyRetin combine both approaches.

A retinol booster enhances the effect of classic retinol and ensures that the skin responds more quickly and effectively—often with improved tolerability. Retinol boosters include ingredients such as Bakuchiol, Granactive Retinoid, or HyRetin, which act on similar biological pathways as retinol or complement and stabilize its performance. This stimulates collagen production, refines skin texture, and visibly softens wrinkles without unnecessarily irritating the skin. For this reason, Retinol Intense can be considered a retinol booster serum: by combining classic retinol with modern retinol boosters, anti-aging performance is intensified while the skin remains supported and protected.

When choosing retinol for experienced skin, focus on higher retinol concentrations combined with complementary phyto-retinols and retinoids. Experienced skin refers to skin that already uses retinol regularly and tolerates it well, allowing more intensive mechanisms to optimize texture, wrinkles, and cell renewal.

Yes. Mature skin particularly benefits from retinol, as natural skin renewal slows with age. High-dose retinol can help support skin structure, visibly soften wrinkles, and improve firmness and evenness. Proper usage and daily sun protection are essential.

Yes, the skin of the upper and lower eyelids can also benefit from retinol, as it is particularly thin and prone to early fine lines. Retinol can help improve skin texture, strengthen resilience, and create a firmer-looking appearance. However, application must be very gentle. High-dose retinol should be used sparingly and kept at a safe distance from the lash line to prevent product from entering the eyes. The eye area is more sensitive than other facial zones and requires gradual adaptation. Mild adjustment reactions at the beginning are possible and not a cause for concern. Think of it as training for your skin: with patience and consistent use, the skin becomes more resilient and visibly smoother and firmer.

The DOC BERGER EFFECT Retinol Serum was part of an independent television product test, including formats such as taff and Frühstücksfernsehen. Participants initially began with a lower retinol concentration before increasing to a higher dosage comparable in intensity to today’s Retinol Intense. Particularly positively rated were:

• Clearly stated retinol concentration
• A clean formulation without unnecessary fragrance or alcohol
• Supportive actives that strengthen the skin barrier

Such characteristics are crucial to ensure that high-dose retinol can work effectively while remaining well tolerated.

In the EU, the recommended maximum concentration for over-the-counter pure retinol in cosmetic products is 0.3%. Higher concentrations fall within the medical domain and are not freely available. Modern formulations combine this maximum concentration with additional retinoid derivatives to further intensify results.
