What is the purpose of the Brightening Vitamin C Serum?

The serum is designed for complex anti-aging care: it brightens skin tone, evens out texture, reduces wrinkles and pigmentation, stimulates collagen synthesis, and increases skin elasticity. The powerful formula provides deep nourishment and a radiant appearance.

When is the best time to use a vitamin C serum — morning or evening?

The serum can be used both in the morning and in the evening. In the morning, it protects the skin from free radicals and enhances the effectiveness of other skincare products, and in the evening, it stimulates skin regeneration during sleep.

Can a Brightening Vitamin C Serum be combined with other active ingredients like retinol or acids?

Combination with acids or retinol is only possible with the gradual introduction of active ingredients into your skincare routine and in the absence of individual skin reactions. For sensitive skin, it is recommended not to combine these active ingredients in one routine. Optimal: use vitamin C in the morning, retinol or acids in the evening.

1

Apply a few drops of the serum to cleansed skin on the face, neck, and decollete.

2

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.

3

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.

If you are pregnant or breastfeeding, consult your doctor before using Brightening Vitamin C 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.

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

5

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

6

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.

7

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.

8

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.

Components

Vitamin C (15% THD) — ultra-stable, fat-soluble, and highly potent form of Vitamin C in the optimal concentration; effectively improves skin appearance without irritation.

3% Niacinamide — synergizes with Vitamin C to inhibit tyrosinase, reduce inflammation, stimulate ceramide synthesis, and strengthen the skin barrier, resulting in less pigmentation and sensitivity.

2,5% Tripeptide-5 — stimulates collagen synthesis alongside Vitamin C; enhances skin firmness and smooths wrinkles.

2% Multimolecular hyaluronic acid complex and 3% Squalane — synergizes with Vitamin C to provide deep hydration across skin layers and create a hydro-lipid barrier that prevents moisture loss, leaving skin hydrated and elastic.

Vitamin E — potentiates the effect of Vitamin C fourfold, protects against photoaging, and gives the skin a healthy, radiant glow.

Bark extract and oleanolic acid — reduce excess sebum, tighten pores, and prevent inflammation.
