Homosalate is an organic compound used in some sunscreens.



  • This ingredient is used in photosensitivity drugs, sunscreens, tanning lotions, moisturizers, and skin protectants. It comes in several forms such as lotions, creams, gels, sprays, sticks, oils, and lip balms. It is used to protect the skin from sun damage and to moisturize the skin.


  • Sunscreens are used to protect the skin from the harmful effects of the sun.
  • They help to prevent sunburn and premature aging (e.g., wrinkles, leathery skin).
  • Sunscreens also help to decrease the risk of skin cancer and also of sunburn-like skin reactions (sun sensitivity) caused by some medications (e.g., tetracyclines, sulfa drugs, phenothiazines such as chlorpromazine).
  • The active ingredients in sunscreens work either by absorbing the sun’s ultraviolet (UV) radiation, preventing it from reaching the deeper layers of the skin, or by reflecting the radiation.


  • Wearing sunscreen does not mean that you can stay out longer in the sun. Sunscreens cannot protect against all of the sun’s radiation.


  • Certain drugs and medications may interact with this chemical ingredient. Patients should tell their doctor about every over-the-counter medication, herbal product, vitamin and nutritional supplement, and prescription medication they use before starting to use products with this ingredient.
  • Patients should also tell their doctor about all topical products they use, such as lotions and other skin products, sunscreens, lip balms, soaps, shampoos, and prescription topical skin medications, before using products with this ingredient. Drugs that may interact with this chemical include anesthetics, sulfa medicines, oral antidiabetic medications, and thiazide diuretics.
