Salish Matter

Co-founded a national skincare brand (Sincerely Yours) and launched into Sephora at age 15 — one of the youngest known founder-led beauty brand launches at Sephora. [estimated superlative — flag for verification]

What they built

Salish co-founded Sincerely Yours, a dermatologist-developed skincare brand built specifically for teens, which launched at Sephora on September 6, 2025 — when she was 15 years old. Inspired by years of dealing with reactive, sensitive skin and finding that most products felt too harsh or simply weren't made for her age group, she channelled her 3.5M-subscriber YouTube community to create something genuinely different: a barrier-friendly, vegan, cruelty-free line (daily moisturizer, hydrating cleanser, soothing facial mist, and mineral sunscreen, all under $30). The launch drew over 80,000 people, sold out in multiple Sephora locations within hours, and reached 200+ Sephora retail doors; 2026 projected revenue is $10–20M with expansion to 400 distribution points. The brand is backed by Strand Equity and has been recognised on Inc.'s 2026 Female Founders 500 — with Salish cited as the youngest founder on the list.
