What is the key benefit of using sunscreens daily?

The key benefit of using sunscreens daily is that they protect against UV radiation damage. Sunscreens are formulated with active ingredients that absorb, reflect, or scatter sunlight, particularly ultraviolet (UV) rays, which can be harmful to the skin. Daily use of sunscreen helps to prevent both short-term effects, such as sunburn, and long-term effects, such as premature aging, skin discoloration, and an increased risk of skin cancer.

The protective action of sunscreen is crucial as UV radiation can penetrate the skin and damage the DNA in skin cells. This damage can lead to negative skin conditions, including various forms of skin cancer. Thus, daily application of sunscreen acts as a critical defense mechanism in maintaining skin health and preventing harmful effects from sun exposure.
