SPF – The Protection Shield, many of us do not know about the SPF and its benefits. The location and area where we stay along with the skin type we have defines the usage of the SPF and its amount. The ideal SPF to be applied safely is considered between 15 – 30. SPF saves us from the UVA and UVB rays of the sun that harm the skin and also penetrate into the inner layers causing damage permanent or temporary.
You must have heard of the acronym SPF aka Sun Protection Factor a lot in the makeup videos, skin care videos or in general. If you are wondering what these three alphabets mean, here’s all you need to know about it. SPF is a measure of how efficiently your sunscreen can protect your skin from UVB rays. These are the kind of radiations that threaten to damage the outer layer of the skin and causes sunburns, skin problems, and in adverse situation, it can also cause cancer. Thus, SPF acts like a protection shield against the sun on your skin against UVB rays.
Kinds of rays
Ultra violet rays can be categorized into two parts: UVA and UVB
UVA rays are long enough to penetrate deep into the skin’s dermal layer causing long-term damage like aging and wrinkles. This layer is where all the cells that stimulate darkening are found. This is why, UVA rays are considered the dominant rays that cause tanning.
UVB rays on the other hand, are shorter so they do not penetrate deep into the skin. However, they burn the outer layer of your skin causing immediate damage like skin burns. The distribution and intensity of the UVB rays vary throughout the day and according to the location.
It is a cream-based formula that protects your skin from the damaging rays of the sun. Broad spectrum sunscreen provides the most protection against UVA and UVB rays. However, no sunscreen can assure 100% protection from the UVB rays, no matter how high the SPF value of the product is. If you use a sunscreen with SPF 15, it will block 93% of the sun and SPF 30 will block 97% of the sun. The protection increases from 98% for SPF 50 and 99% for SPF 100. The SPF number denotes the approx. minutes it allows you to stay in the sun without getting burned. For example, SPF 15 means you can stay for 150 minutes in the sun without getting your skin burned.
