Sunscreen lotion is important-to prevent skin cancer
What is a Sunscreen Lotion?
Sunscreens lotions are UV Radiation sun-blocks have a unique molecular structure that absorbs the high-energy ultraviolet (UV) rays and converts them to a less harmful energy level, thus preventing the harmful effect of the UV rays from penetrating the skin.
What is SPF?
SPF, an abbreviation for sun-protection factor. SPF is given a numerical rating that tells us the degree of protection that is being provided by the sunscreen lotion such as 15, 30, or 50. This tells us how long a topical sunscreen remains effective on the skin. A user can determine the duration of effectiveness simply by multiplying the SPF by the length of time it takes for him or her to suffer a tan without sunscreen. Sunscreen should also be applied at least 30 minutes before going outdoors. According to Dermatologists, sunscreens should be applied 15 to 30 minutes before sun exposure, followed by one reapplication 15-30 minutes after the sun exposure begins. Further reapplication is only necessary after activities such as swimming, or after excessive sweating.
Which is the ideal SPF for Indian skin?
According a recently (2007) published article in the Indian Journal of Dermatology, Venereology, and Leprology, the ideal choice of sunscreens are those that effectively block both Ultraviolet A & B radiation, which is done with an SPF of 30 or greater (Broadspectrum Sunscreen Lotions are ideal). The ideal sunscreen, therefore, should have a high SPF rating and be non-toxic, water-resistant and, importantly, not too expensive!
