I decided to compile all the posts around sunscreen into one, and this also makes for good archiving, right? Please don't forget to click the share button my loves!
"Dermatologists with the Skin Cancer Foundation (2) estimate that 90 percent of visible aging comes not from the number of candles on your birthday cake but the hours you've spent in the sun. Wearing sunscreen daily saves your skin from years of visible damage later."
WHY YOU SHOULD WEAR SUNSCREEN DAILY
- Sunscreen is important for all skin types and tones!
- Sunscreen keeps your skin tone even. In addition to slowing aging of the skin, sunscreen prevents facial brown spots and skin discolourations.
- It Protects Your Skin from UV Rays: The depletion of the ozone layer has increased our risk of sun damage from harmful UV rays.
- By applying sunscreen each day, you reduce the risk of skin cancer.
- Sun damage from UV rays causes photoaging of the skin, which is characterized by a thick, leathery look; discolouration; and a breakdown of collagen, which contributes to lines, sagging and wrinkles.
SPF stands for SUN PROTECTION FACTOR
Why is there a number after SPF? The SPF number tells you how long the sun’s UV radiation would take to burn/redden your skin when using the product exactly as directed versus the amount of time without any sunscreen.
So ideally, with SPF 30 it would take you 30 times longer to burn than if you weren’t wearing sunscreen. For example if it takes you 5 minutes to burn without sunscreen you multiply that time by the sun protection factor; 5minutes X SPF 30= 150minutes
"UVB rays cause sunburn and play a key role in developing skin cancer. A sunscreen’s SPF number refers mainly to the amount of UVB protection it provides.
UVA rays cause skin damage that leads to tanning as well as skin aging and wrinkles. The shortest wavelengths of UVA rays also contribute to sunburn. It’s important to look for the words “broad spectrum” on a product’s label, which means it has ingredients that can protect you from UVA as well as UVB rays.
UVC rays, UVC radiation is the highest energy portion of the UV radiation spectrum. UVC radiation from the sun does not reach the earth's surface because it is blocked by the ozone layer in the atmosphere. Thus, the only way that humans can be exposed to UVC radiation is from an artificial source like a lamp or laser." _ sourced from google, science & cosmetics platforms.
SO WHICH SPF SHOULD I GO FOR PABI?
- Go for broad spectrum, this will protect you from the different sun rays.
- Look at your lifestyle, if you spend more time outdoors go for SPF 50, if you are indoors and don't spend a lot of time by sun ray exposed areas wear SPF 30.
- Reapply your sunscreen every 2-3hours.
- Pay attention to the expiration date on the bottle. Sunscreen loses its effectiveness over time.
TIPS & SPF CALCULATIONS
(TIME IT TAKES TO BURN X SPF= PROTECTION)
10MINS X SPF 30 = 300MINUTES, BUT ALWAYS REAPPLY AFTER 2-3HOURS.
If you have sensitive skin that has trouble tolerating sunscreens or cosmetics, look for fragrance free / low irritant sunscreens.
If your skin is dry, you will benefit from sunscreen in a moisturising cream.
If you have oily skin or readily develop acne, choose a sunscreen in a lighter base. One formulated for oily skin types.
Go for light to creamy formulas depending on what your skin needs.
If your skin is combination, play around with formulas for oily or dry skin types depending on what your skin needs.
