Gluhen FC Vitamin C Serum 30ml

This serum is designed for all skin types, including skin that looks dull, uneven, or marked by post-acne discoloration. It is best used as part of a regular face-care routine. If you have very sensitive skin or active irritation, patch test first and start with less frequent use. Discontinue if burning, redness, or persistent stinging occurs.

Apply it after cleansing, before moisturizer. It can be used in the morning or evening, but daytime use should always be followed by sunscreen. Vitamin C products are commonly used in the morning for antioxidant support, while evening use is also acceptable if it suits your routine. Avoid layering with irritating actives if your skin is reactive.

Avoid direct contact with the eyes, broken skin, or freshly shaved areas. If you are using exfoliating acids, retinoids, or strong acne treatments, introduce this serum slowly to reduce irritation risk. Store it tightly closed, away from heat and direct light. If you are pregnant, breastfeeding, or managing a skin condition, consult a dermatologist before regular use.
