What is SPF? Is SPF the higher the better?
SPF is Sun Protection Factor. Usually, the SPF value will be labeled on the packaging of the sun care products for consumer to make a choice conveniently. However, is SPF the higher the better?
When the skin is in a condition whereby the weather is hot and humid, sebum will disperse towards skin epidermis in semi-fluid form. At this time, if a sun care product with high SPF is used, the pores will be enlarged, skin will lose hydration and tend to be sensitive, coarse and thick dead skin. Choice of sun care products should be made according to the humidity and temperature of different country, it is not true that it’s the better the higher is the SPF.
The best value of SPF for Sun Care products to be used in Tropical Countries should be between 15-20.
