The purpose behind every batch

Thoughtful ingredients.
Clear explanations.
Accessible care.

I started making skincare for my own dry skin and shared it with family members with different skin types, in California and on the East Coast. That personal curiosity grew into Sisothecary.

Hydration: Hyaluronic acid and panthenol bind water for soft, hydrated-feeling skin. HA Serum is coming soon.

Antioxidant support: Vitamin C and CoQ10 complement daily skincare in AM Facial Oil.

Smoother-looking texture: Bakuchiol, included in PM Facial Oil, has been studied for the appearance of fine lines and uneven tone. Ingredient research does not establish the same results for our finished product.

Moisture-barrier support: Ceramide complex and squalane help retain moisture for a comfortable skin feel. Ceramide complex is included in HA Serum; squalane is included in AM Facial Oil.

Sisothecary formulations have not undergone clinical trials. Facial oils do not provide SPF.
