A: We recommend applying moisturiser after applying the vitamin C face serum if you feel the need to dilute.

Q5: What to avoid with vitamin C serum?

A: Here are a few things you must avoid when applying vitamin C brightening serum ;

  • Avoid mixing the Vitamin C serum with Retinol or niacinamide. This is because both these products cancel each other’s effect. In some cases, it may even lead to skin redness.
  • Skipping sunscreen after applying vitamin C brightening serum during the day. If you miss doing this the serum can oxidise and your skin tone may turn yellow, or orange.
  • Not storing it in a cool dark place. Exposure to sun or heat can oxidise the vitamin C Serum.

Q6: How do I know if my vitamin C serum is working?

A: You will know if your vitamin C serum for dry skin is working from the visible improvement in your skin tone, skin brightening, and the appearance of a soft glow. There will be a reduction in blemishes, dark spots, and signs of ageing.
