Can I use COSRX Refresh AHA BHA Vitamin C Booster Serum every day?

Yes — it is formulated for daily use, but if you are new to acids or have sensitive skin start 2–3 times per week and gradually increase.

Is this serum suitable for sensitive skin?

The formula is hypoallergenic, dermatologically tested and allergy tested, making it suitable for many sensitive skins, but always patch test before full use.

Do I need to wear sunscreen when using this serum?

Yes — because the serum contains AHA/BHA which can increase sun sensitivity, you should apply a broad-spectrum SPF 30+ each morning.

Can I use this serum with retinol or other direct acids?

Avoid layering it with strong retinols or other direct acids/Vitamin C serums in the same routine; use them on alternate days or consult a skincare professional.

How should I store the serum and what is its shelf life after opening?

Store in a cool, dry place away from direct sunlight with the cap tightened; no refrigeration is needed and the product has a 12-month shelf life after opening.
