Medium protection refers to sunscreens with a sun protection factor ranging from 15 to 30 SPF. The acronym SPF stands for 'Sun Protection Factor' and indicates how many times longer skin can be exposed to the sun before reddening, compared to unprotected skin. For example, a product with SPF 15 blocks approximately 93% of UVB radiation, while SPF 30 filters roughly 97% of these rays. This type of protection is suitable for everyday wear or shorter sun exposure for individuals with a normal skin phototype who do not easily get sunburned.
