Checks before scaling

01

Review cosmetic claim wording

Concern-care lines should describe appearance and cosmetic support without implying medical treatment.

02

Concern-care language needs claim control

Calming, troubled-skin, dark-spot, redness, firming, and barrier language should stay cosmetic-safe and avoid treatment wording.
