Why is there a skin diagnostic test in the kit and how does it work?

The diagnostic test included in the kit helps accurately determine your skin’s current condition and key needs before starting the serum. In just a few minutes at home, you can assess your skin’s pH level, skin type, and pore condition to gain an objective understanding of its balance. By scanning the QR code, you will receive an online report with an explanation of the results and personalized skincare recommendations. Repeating the test after using the serum allows you to compare the results and evaluate changes in skin radiance, tone, and overall condition.

Is this starter pack suitable for sensitive skin?

Yes, the starter pack is even suitable for sensitive skin. The formula contains 15% THD Vitamin C — an ultra-stable, fat-soluble form of vitamin C in an optimal concentration that effectively improves the appearance of the skin and is well tolerated without irritation, making it suitable for long-term use.

Can serum be used in the morning and combined with SPF and makeup?

Yes, the serum can be used both in the morning and in the evening. Its light texture is quickly absorbed, gives the skin a glow, and blends well with makeup. In the morning, after applying the serum, it is important to use SPF 50 to protect the skin and prevent unwanted reactions.

Vitamin C Serum: Apply a few drops of the serum to cleansed skin on the face, neck, and decollete. After the serum, apply: In the morning — HydraFusion Hydrating Gel Cream or C-Illuminating 3D Moisturizer, followed by SPF50. If the serum provides enough hydration, you may skip the cream and apply SPF only. In the evening — SuperBiotic Regenerating Cream. Do not combine with products containing retinol in the same routine — this may cause irritation, especially for sensitive skin. The optimal regimen: vitamin C in the morning, retinol in the evening. The product is sensitive to temperature changes and sunlight; store the serum at room temperature (below +25 °C), in a dry place away from direct sunlight.

How to use Diagnostic Test: 1. Skin pH Test: Cleanse your face and allow your skin to rest for 15 minutes. Do not apply moisturizer or makeup after cleansing. Open the packet with the activating solution and dip the test strip into the liquid. Shake off any excess (the strip can only be used once). Immediately place the wet strip, indicator side down, onto clean facial skin (without makeup) for 20 seconds. Compare the result with the color scale to determine your skin’s pH level. 2. Skin Type and Pore Test: Cleanse your face and allow your skin to rest for 15 minutes. Do not apply moisturizer or makeup after cleansing. Place the test strips on the indicated areas of your skin. Leave each strip for 3–5 seconds. Refer to the results scale to determine your skin type and pore condition. Scan the QR code to access your test results.

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. Consult your doctor before use.

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.

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.

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.

When starting products with active ingredients such as retinol, acids, or 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 typically appears 2–3 weeks after starting actives and can last up to 9–10 weeks, so it is important not to drastically change your routine and to allow the skin time to adapt. If your skin condition significantly worsens and the reaction does not subside, consult a dermatologist or skincare professional.
