Vitamin C Buying Guide

✦

L-Ascorbic Acid (10-20%) is the most studied form — potent but can irritate sensitive skin. Start at 10% and work up.

✦

Sodium Ascorbyl Phosphate (SAP) is gentler and more stable — great for acne-prone skin. Melano CC and TruSkin use this form.

✦

Vitamin C + Vitamin E + Ferulic Acid is the gold-standard combo — they synergize to double UV protection and stability.

✦

Store in a cool, dark place. Oxidized vitamin C turns orange/brown and loses efficacy. Toss it if it changes color.
