Have you ever wondered what is the full form of SPF? Tap to check out its full form and know how it works for your skin.
SPF is a measuring factor that determines how well a sunscreen protects your skin from the harmful ultraviolet rays of the sun.
We use SPF daily to protect our skin. But, do you know its full form? SPF stands for Sun Protection Factor (SPF).
A SPF is a number which tells how much the ultraviolet rays of the sun would take to sunburn your skin while using sunscreen versus while not using one.
A high number of SPFs indicates high protection against UVB rays on the skin. For example, a sunscreen with SPF 30 would protect your skin 30 times longer than a bare skin.
The ultraviolet (UVB) rays of the sun can badly affect your skin. If you do not wear sunscreen, it can cause sunburn or even cause skin cancer.
As per the Skin Cancer Foundation, while buying sunscreen, always look for a broad-spectrum sunscreen with a high SPF of 50 for longer sun protection.
