Ingredient analysis and how the ad lines read
Read on 2026-09-22
What is this product?
A 7g herbal-luxury sun stick built on three modern UV filters, suitable for easy on-the-go sun care, though it contains fragrance and fragrance allergens that sensitive users should weigh.
What makes it different?
The formula pairs three UV filters, placed at positions 8, 9 and 13, with a wax and ester stick base that spreads smoothly. A long run of traditional herbal extracts including ginseng root extract appears in the back portion of the list, alongside astaxanthin and tocopherol. Calamine at position 11 gives the stick its reddish tone. Concentrations are not disclosed for any of these.
