This page contains brief details about the drug , it's indication, dosage & administaration, mechanism of action, related brands with strength, warnings and common side effects.

Background and Date of Approval

Sunscreen was initially approved by the U.S. FDA in August 1978 as an over-the-counter medication. 

In the year 2019, the FDA proposed new rules to update sunscreen regulations, including changes to active ingredients, maximum SPF levels, and labelling requirements.

Mechanism of Action of undefined

Sunscreens absorb or reflect UV radiation to protect the skin. Chemical sunscreens absorb UV rays and convert them into heat, while physical sunscreens containing zinc oxide or titanium dioxide reflect UV rays. Both types protect the skin from UVA and UVB rays, reducing the risk of sunburn, premature ageing, and skin cancer.

Uses of undefined

Sunscreen is essential for protecting the skin from harmful UV radiation, which can lead to various skin issues. Regular use of sunscreen offers several benefits, including:

  • Prevents sunburn by blocking harmful UVB rays.
  • Reduces the risk of skin cancer by protecting against UV radiation.
  • Prevents premature ageing of the skin by shielding it from UVA rays.
  • Prevents skin damage such as sunspots, wrinkles, and pigmentation.
  • Provides broad-spectrum protection against both UVA and UVB rays.
  • Protects sensitive skin from UV-induced irritation and inflammation.
  • Helps maintain even skin tone by reducing the risk of pigmentation.
