Soltego

Soltego is a private biotechnology and bio-cosmetic company focused on skin pigmentation biology and photoprotection. The company is developing and commercializing topical small-molecule products based on salt-inducible kinase (SIK) inhibitors that stimulate the skin’s natural pigmentation and repair pathways without UV exposure. Its strategy appears to span both aesthetic skincare products and prescription-oriented dermatology applications, including products for sun protection, natural tanning, and pigmentation-related conditions. Soltego’s scientific foundation comes from research by founders David Fisher and Nathanael Gray on the molecular pathways controlling tanning and eumelanin production. The company positions its technology as a way to help prevent UV-induced skin damage and address cosmetic and therapeutic skin needs.
