How is X-Strength Retinol Serum different from other retinoid serums?

X-Strength Retinol Serum features a highly concentrated 8% retinoid complex: 5% new-generation granate retinoid and 3% blue-green algae — a stable form of retinoid that works without the risk of irritation. The formula is supplemented with moisturizing and soothing ingredients (multimolecular hyaluronic acid complex, squalane, provitamin B5, allantoin, vitamin E, natural oils) that minimize dryness and discomfort. The revitalizing P3 peptide enhances the anti-aging effect of retinoid and increases skin elasticity.

How can you help your skin gradually adapt to a high-strength retinoid?

To gently adapt your skin to X-Strength Retinol Serum, start with two applications per week in your evening routine, then gradually increase the frequency of use to daily. We recommend applying the serum to dry, unsteamed skin and leaving it on for 15 minutes before applying cream.

Can X-Strength Retinol Serum be combined with a vitamin C or acid-based serum in the same routine?

X-Strength Retinol Serum can be combined with vitamin C or acids, but they should be used separately in your skincare routine: vitamin C or acids are best applied in the morning, and retinol in the evening.

1

Apply a few drops of the serum to cleansed skin on the face, neck, and decollete in the evening. Do not apply to damp or steamed skin.

2

After the serum, apply HydraFusion Hydrating Gel Cream or SuperBiotic Regenerating Cream. In the morning, always follow with Sunscription SPF50.

3

If you are new to retinol, start with 2 times per week, gradually increasing frequency to daily use. If your skin is already accustomed to retinol, you can apply the serum every evening or alternate with Powerful RetinOil. For maximum results, use together with Advanced Retinol Toner — this ensures a complete cycle of renewal and intensive care.

For sensitive skin, do not combine with acids in the same routine to avoid irritation. If your skin is more resilient, you may combine the serum with acid-based products to enhance the effects of retinol. For non-sensitive skin, if the serum provides sufficient hydration, you may skip the cream in the evening and apply a restorative product in the morning instead. Retinol-based products are not recommended during pregnancy or breastfeeding. Please consult your doctor before use.

1

If you are pregnant or breastfeeding, consult your doctor before using X-Strenght Retinol Serum. If an adverse reaction occurs, discontinue use of the active product for 2–5 days, then reintroduce it gradually. 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, add retinoid-based products.

2

Store the product at room temperature (up to +25 °C) in a dry place, protected from direct sunlight.

3

During sunny periods, always apply SPF50 every morning before going outdoors. In the evening, complete your routine without SPF products.

Products containing acids and retinoids may cause temporary redness or irritation — this is an individual skin response.

5

INSTYTUTUM formulas contain a high concentration of active ingredients. To minimize the risk of irritation, introduce new products gradually, starting with 2–3 times per week.

6

Recommendations are based on the use of products within the INSTYTUTUM range. Combining with products from other brands may increase sensitivity and lead to unpredictable reactions.

7

When starting products with active ingredients (retinol, acids, vitamin C), the skin may temporarily react with breakouts, flaking, or irritation — this is a purging phase that indicates the activation of cellular renewal and detoxification; it usually appears 2–3 weeks after beginning active ingredients and can last up to 9–10 weeks, and during this time it’s important not to drastically change your routine and allow the skin to adapt, but if the condition worsens significantly or the reaction does not subside, consult a dermatologist or skincare professional.
