Updated June 2026. Based on official brand communications and Wikipedia-level public references. Editorial summary — not regulatory or medical advice.

Quick answer

Best known for its My Signature C Source 20% vitamin C serum and Vita B3 Source niacinamide serum, alongside its AC Fighting AHA BHA PHA exfoliating toner.

Best for

K-beauty shoppers with $15–$30 routine budget who want recognizable hero products and clear category strengths. Strongest in serums, toners, exfoliants, suncare.

What to skip if

You only want to try one product — start with the hero product rather than a full routine swap. If the listed hero ingredients don't match your skin needs, the rest of the line probably won't either.
