How do I use COSRX Hyaluronic Acid 3% Serum in my skincare routine?
After cleansing and toning, apply 2-3 drops to damp skin on the face and neck. Gently press in until absorbed, then follow with moisturizer and sunscreen during the day or a night cream in the evening.
Can I layer this serum with other active ingredients like retinol or vitamin C?
Yes. The hyaluronic acid serum is gentle enough to layer with most actives. Apply it first on damp skin, then follow with vitamin C in the morning or retinol in the evening for enhanced results.
How long does a 20ml bottle typically last with daily use?
With 2-3 drops applied twice daily, a 20ml bottle generally lasts 6-8 weeks, depending on how much you use per application.

Are there any side effects I should be aware of?
The serum is hypoallergenic, dermatologist-tested, and free from common irritants. Side effects are rare, though anyone with known sensitivities should review the full ingredient list before use.
Is this product safe to use during pregnancy or while breastfeeding?
The fragrance-free, hypoallergenic formula is generally considered safe during pregnancy and breastfeeding. However, you should always consult your healthcare provider before introducing new skincare products during this time.
How is a hyaluronic acid serum different from a regular moisturizer?
A hyaluronic acid serum delivers concentrated hydration deep into the skin, while a moisturizer seals in moisture and provides surface-level nourishment. Layering both gives optimal hydration and barrier protection.
