Krizhtinasaur review for Hyper Vitamin C 23 Serum

This 23% Vitamin C serum is an excellent addition to my routine, especially these past few weeks I'm looking for a vit. C to brighten and fades my brown spots on my face. So far, it improves my skin complexion and texture. Since vitamin C can increase the skin's sensitivity to the sun, I used broad-spectrum sunscreen w/ SPF 30 when incorporating this serum into my daytime routine.
