Is this serum suitable for sensitive or reactive skin? — DNC Hyaluronic acid 3 ml (hyaluronovaya acid)

The formula is designed as a lightweight, concentrated hydration booster without heavy oils or occlusive ingredients, which many people with sensitive skin tolerate well. However, any new cosmetic — especially one with active humectants — should be introduced slowly. Start by applying it every other day or only in the evening for the first week, and observe how your skin responds. If you experience stinging, redness, or increased sensitivity, reduce frequency or pause use until the skin barrier recovers. The product instructions specifically advise against applying to irritated or damaged areas. If you have a diagnosed skin condition such as eczema, rosacea, or contact dermatitis, or if you are undergoing dermatological treatment, consult your specialist before adding new products to your routine. Patch testing on a small area behind the ear or on the inner forearm for a few days can also help identify individual reactivity before full-face application.
