What is a SPF☀?
The Sun Protection Factor is a measure of how well a sunscreen will block-out UV rays. It basically measures the time a sunscreen can shield the skin 🛡
For example, it takes 8 minutes for my skin to burn without SPF, but with an SPF of 10 it will offer me 10 times that amount of protection, so I’ll be protected for 80 minutes. However, this estimation depends on skin type and intensity of the sun. Most importantly to maintain a high level of protection, the sunscreen should be reapplied throughout the day ♻
What are UVA & UVB Rays 🌤 ?
A broad spectrum SPF will protect the skin from UVA rays and UVB rays. UVA rays have the power to get though our skin barrier all the way to the dermis. They damage our blood vessels as well as break down collagen and elastin fibbers. UVB rays are the one causing damage to our DNA. Think UVA-Ageing, UVB-Burning.
Healthy Sun Exposure ☀
Many experts believe that melanoma, which is one of the deadliest types of cancer can be prevented by sun exposure. Yes, that’s right ! It can even help melanoma cancer patients to raise their survival rate!
If you haven’t checked your moles with a doctor please terminate reading. Bye. For the others, let the sun boost your health. You only need to expose your skin for around half the time it takes your skin to begin to burn. The skin will activate Vitamin D production and absorb the benefits of the sun. Vitamin D helps to eliminate the progression of cancer cells 👌 (best times : 10 am or 4pm when UVB rays are not too strong).
Other than this “Vitamin D Stock Up time”, it is essential to protect your skin as much as you can. Search for an SPF that covers both UVA and UVB protection, has a moisturising agent such as glycerin to prevent dehydration and an antioxidant, such as Vitamin E.
