Frequently Asked Questions

When should I apply vitamin C in my routine?

Apply in the morning after cleansing and before your moisturiser and SPF. Vitamin C works synergistically with SPF to provide enhanced protection against UV-induced skin damage.

How do I know if my vitamin C serum has oxidised?

Oxidised vitamin C turns orange or brown and loses its efficacy. C-Glow’s stable formula is designed to resist oxidation — store in a cool, dark place and use within the recommended period after opening.

Is 15% vitamin C suitable for sensitive skin?

15% is a high concentration that may cause tingling or mild irritation for sensitive skin types. If you’re new to vitamin C, start with every other day and build up to daily use as your skin adjusts.

How long before I see brightening results?

Most users notice improved radiance within 2–4 weeks, with more significant improvements in dark spots and skin tone over 8–12 weeks of consistent daily use.
