X-Strength Retinol Serum – a concentrated next-generation anti-aging serum with retinoid. The powerful formula with an 8% retinoid complex works simultaneously against wrinkles, pigmentation, and inflammatory signs. Thanks to the INSIDE & OUT technology, the serum ensures deeper penetration of active ingredients, supports cellular-level regeneration, and maintains skin comfort.

Why this one:

• The advanced formula provides higher course efficacy without irritation, even for sensitive skin.
• High-concentration next-generation retinoid (HPR) – an innovative form with strong clinical evidence in cosmetology, delivering visible results from the first weeks of use.
• One serum replaces multiple products – restoring firmness, brightening the complexion, reducing pigmentation and inflammation – without complicated multi-step routines.
• Maximum efficacy with skin comfort: the formula hydrates, soothes, and supports the skin barrier.
• A modern approach to skincare – enhances cellular activity and helps reduce the skin’s biological age.

Result: The skin is visibly renewed, firm, and radiant. Fewer wrinkles, pigmentation, and inflammation.

Suitable for:

• Your skin is losing firmness and tone.
• You have pigmentation, post-acne marks, or uneven skin tone.
• You need products to reduce inflammation and tighten pores.
• You are looking for an effective retinol without the risk of irritation.

Application

• Apply a few drops of the serum to clean skin on the face, neck, and décolleté in the evening. Do not apply to damp or steamed skin.
• After the serum, apply HydraFusion Hydrating Gel Cream or the restorative SuperBiotic.
• In the morning, always use Sunscription SPF50 sunscreen.
• If you are using retinol for the first time, start with twice a week, gradually increasing to daily use. If your skin is already accustomed to the ingredient, the serum can be applied every evening or alternated with Powerful RetinOil. For maximum results, use together with Advanced Retinol Toner. Your skin will receive a complete renewal cycle and deep care.

Safety

• During pregnancy or breastfeeding, consult your doctor before use.
• If a negative reaction occurs, discontinue use of the active product for 2–5 days, then gradually reintroduce it into your routine.
• If you plan to use acids and retinol together – start with acids (2–3 times per week); after 10–14 days, if no irritation occurs, introduce retinoid products.
• Store at room temperature (up to +25°C) in a dry place, protected from direct sunlight.
• During sunny periods, always apply SPF50 every morning before going outside. In the evening, complete your routine without SPF products.
• Products with acids and retinoids may cause temporary redness or irritation – this is an individual skin response.
• INSTYTUTUM formulas contain a high concentration of active ingredients. To minimize the risk of irritation, introduce new products gradually, 2–3 times per week.
• Recommendations are based on the use of products within the INSTYTUTUM line. When combined with products from other brands, increased sensitivity and unpredictable reactions may occur.
• After using products with active ingredients such as retinol, acids, or vitamin C, the skin may temporarily react with breakouts, flaking, or irritation. This is a natural skin purging process, indicating activation of cellular renewal and detoxification. It usually appears around 2–3 weeks after starting active ingredients and can last up to 9–10 weeks. During this period, do not abruptly change your routine – allow your skin time to adapt. If the condition noticeably worsens or the reaction does not subside, consult a dermatologist or cosmetologist.
