Firstly how well do we know our sunscreen?

Well sunscreen is a lotion or gel that protects us from the harmful ultraviolet radiation, i.e., UVA and UVB rays. It is advisable to apply sunscreen at least 30minutes before exposing our skin to harsh sun radiation. And a reapplication is needed once we sweat out or after we wash or come in contact with water.

Sunscreens are graded by SPF - Sun Protection Factor, so if your sunscreen reads SPF 20, then 1/20 of the solar radiation reaches our skin.

 

Pros of Sunscreen:

The obvious benefits are protection from sunburns and sun sensitivity in fair skinned individuals. Recent researches have validated it use in delaying premature ageing such as, wrinkles and sagging of skin. Also reduces the risk of acquiring skin cancers like melanoma and squamous cell carcinoma

 

Cons of Sunscreen:

The ingredients of sunscreen may trigger some kind of allergic reaction in some people. It may worsen acne and may also present are pus follicles as sun-block tend to block the skin pores. May also predispose us to breast cancers. Minimal degrees of Vitamin Deficiency had been reported.

Lately, there has been lot of fuss over the use of high SPF sunblock. It is wise to use sunscreens suitable to the skin type, and SPF of 30 - 40 is the best range, because none of the sunscreens can provide 100% protection from the solar radiation, so it is best to re-apply often than use of high SPF.

Take Care!! Stay uncovers or under sunscreen!!
