Clothing that's also skincare
Fabrics with a UV Protective Factor can block >99% of UVB rays and 96-98% of UVA rays (the ones tied to aging and deeper skin damage) while SPF 30-50 sunscreens may only block 76-94% of UVB and 54-82% of UVA.

About Lys' Founder, erin
I knew red hair and fair skin gave me a greater chance of skin cancer so I wore sunscreen most days, and definitely on the beach. But then, I had a basal cell carcinoma removed at 33.
I created Lys–Norwegian for "light" and an homage to the ancestry that gave me red hair and pale skin–when I couldn’t find UPF clothing that fit my style. Using my background and networks in apparel, supply chain, strategy, and operations, I decided to make my own.
*Though I may have recruited my aesthetically- skilled sister, Hana, to do the branding.
