The 20 g bottle is best suited to those already experienced with vitamin C.

Why you'll love it

  • 20 g bottle, recommended for those with prior vitamin C experience

How to use

After cleansing and toning, apply 1 to 2 drops to face and neck. Pat gently until absorbed. Follow with moisturizer. Use in the morning, and always apply sunscreen afterward, as vitamin C increases photosensitivity.

FAQs

Why does the serum have two layers?
The oil layer sits on top of the pure vitamin C to slow oxidation and leave a moisturizing finish once blended in.

Do I need sunscreen after using it?
Yes, always apply sunscreen afterward, since vitamin C can increase the skin's sensitivity to light.

Is this a beginner vitamin C serum?
No, at 23% concentration it's recommended for those who already have experience with vitamin C.
