All you Need to Know | Sunscreen Protection and UV Rays

As a brown skin girl, my skincare concerns are usually focused on uneven complexion, hyper-pigmentation, acne, blemishes and dark spots. It goes without saying, but I will say it…… Daily sunscreen is essential to having great skin.

What is SPF?

SPF stands for Sun Protection Factor. A sunscreen’s SPF number refers mainly to the amount of UVB protection it provides. SPF 30 blocks nearly 97% of UVB radiation, SPF 50 blocks about 98%, and SPF 100 blocks about 99%.There are also two types of ultraviolet rays:

  1. UVA rays which causes skin damage that leads to tanning as well as skin aging and wrinkles.
  2. UVB rays which causes sunburn and play a key role in developing skin cancer.

SPF protects every skin type so don’t think only people who burn easily need it. In fact, what most people call aging is actually sun damage. Check out this picture of a truck driver. Can you tell which side of his face was exposed to UVB rays?

How Often Should You Use Sunscreen?

Use a generous amount (otherwise you are just wasting product) of sunscreen 30 minutes before being exposed to the sun. Depending on the SPF factor, it can last up to two or three hours. It is important to always reapply when you’ve been in the sun for long periods of time, been sweating, or gone for a swim.

“Most of the cumulative sun damage we see on the skin is NOT from the beach, It’s from daily activities and intermittent, so called ‘incidental’ sun exposure. All that sun really adds up and over the years it makes a huge difference.”.


I would recommend getting a “broad spectrum” sunscreen that protects from UVA and UVB rays. For those of us living in sunny countries, I recommend SPF 30-50. I am currently using ACM Depiwhite.S SPF 50 Sun Protection.
