Best Vitamin Cs Part 1 #shorts

Short transcript of a YouTube skincare video by Shereene Idriss explaining differences between active (L‑ascorbic acid) and ester/inactive vitamin C forms. Advises that L‑ascorbic acid (active) can be reactive and irritating, generally unnecessary above 20% concentration; recommends Paula’s Choice Vitamin C15 Booster for morning use under sunscreen but not to combine with retinol at night. Recommends gentler ester forms (Summer Fridays CC Me serum containing 3‑O ethyl ascorbic acid and ascorbyl glucoside, and a 2‑in‑1 gel moisturizer) as beginner-friendly, usable morning and night.
