There are numerous benefits of using sun protection and they normally stem from being preventative to the precursors of ageing and hyperpigmentation. It cannot be stressed enough how important it is to use sunscreen regularly and liberally in order to prevent photo-ageing and damage.
There are various factors to consider when choosing a Sun Protection product, one of the most important being the choice of the SPF strength but there are in fact other factors to consider. The SPF (Sun Protection Factor) measures the amount of UVB absorption, but there is no method of measuring UVA absorption. The only way to determine if a sunscreen protects against UVA and UVB radiation is to look at the ingredients. A good sunscreen should have an SPF of at least 30 and contain avobenzone, titanium dioxide, or zinc oxide.
