SUNSCREEN - How, Why, When to Use




What is SUNSCREEN

 Sunscreens are basically a lotion or cream base chemical which prevent the skin from UV Rays present in sun light and real cause of skin disease. It mainly stops UV-B rays but now few sunscreen has come in market which prevent both UV-B and UV-A. 


 What is SPF?

Sun protective factor is a unit to measure strength of sunscreen. There are wide range of SPF creams are available in market. More the SPF more the cost and more the strength. 30 SPF cream stops almost 95% of rays coming to skin and 50 SPF stops 99% of rays. So as SPF increases market prices also increase but there is not much change in work efficiency. I recommend 30-50 SPF Creams always. Although there are creams which claims SPF more than 50 but practically does not make much difference. 


How to use sunscreen?

Sunscreen should be used in day and does not matter whether sun light is present or not. Because UV Rays always comes to earth irrespective of cloud . Ideally sunscreen should be used every 3-4 hourly but I always advice patients to use it thrice in a day . I set the time on 9 O' clock then 12 O' clock and 3 O'clock. Sunscreen should be used not only face but all sun exposed part of body like hand , neck, Thicker the layer applied on skin more the effect of sunscreen . So i suggest the patient to apply multiple layer and thicker layer. Apply sunscreen half an hour before if going out in sun. 

Should i use cream in home ?


YES, normal light also contain same UV rays. Many people have tendency to get tanning even in home on exposure to normal light. i suggest to use sunscreen regularly while in home or out side of home. So to minimize the effect of light absolutely we should use sunscreen in day irrespective of presence of sun light and place. 

Does Sunscreen cause ACNE ,Black heads?

No, theoretically sunscreen does not cause any skin problems including acne. But very few people may have some kind of allergy to sunscreen. Sunscreen causes contact dermatitis and in such case we have to change the brand or completely stopped. 

I Have Oily Skin

There are lotions and creams which are greasy and does not suits oily skin. Initially we didnt have any options because greasy and sticky character of sunscreen increase the SPF but now non sticky , non greasy creams have come. Ranbaxy manufactures Suncros Soft lotion which is totally suitable for oily skin and i personally got very good response. 

Make up and SUNSCREEN

Sunscreen is a non reactive chemical and does not harm skin if used with makeup. Although i advice to use makeup minimally while using sunscreen. Eyeliner, lipsticks , can be used but other cosmetics used on face skin should be avoided.
