Company profile

researched Aug 2026

Lygg Corporation is a chemistry-driven personal care ingredient developer working on new sunscreen and anti-aging actives for skincare. The company's stated premise is that up to 90% of skin aging is caused by UV light, most of it UVA, while only one FDA-approved chemical ingredient protects against UVA. Lygg has developed a patented, photostable and safe ingredient that it says triples current UVA protection.

The company describes its suncare ingredients as inspired by lignin. It operates with a very small team, listed as one employee, and maintains an address at 2627 Hanover Street, Palo Alto, California, while Y Combinator lists its location as San Francisco.

Founding story

Founder and CEO Graham Dick, originally from Vancouver, Canada, earned a PhD in Chemistry from Stanford University and was previously a postdoctoral researcher at EPFL in Lausanne, Switzerland. He founded Lygg in 2020 following the ban of two common sunscreen ingredients in Hawaii and amid growing concerns about the skin penetration of remaining approved ingredients, with the aim of creating a new generation of sunscreen ingredients.

Business model

Lygg develops sunscreen and anti-aging active ingredients rather than finished consumer products, placing it in personal care product manufacturing.

Full profile — market position, technology, go-to-market, geography, history

Market position

Lygg positions itself against the limited set of approved UVA-protective chemical filters, noting that only one FDA-approved chemical ingredient offers UVA protection and that two common sunscreen ingredients have been banned in Hawaii.
