Suncreen and Dark Skin 2
There are 2 broad categories of sunscreen. 1st is physical, which contains minerals titanium dioxide and zinc oxide. Zinc oxide and
titanium, blocks and scatter UV rays before they penetrate your skin.
This is the type that dark skin tend to avoid because it often leaves a white residue on
dark skin, the whiteness of zinc oxide and titanium dioxide can leave dark skin looking
2nd category is chemical. The active ingredients in many chemical sunscreens, including oxybenzone and octisalate. Absorb UV rays before they damage your skin.
Oxybenzone and octinoxate these are UV filters that can be harmful for the environment.
Oxybenzone is a common chemical found in many sunscreens and has been shown to gravely damage coral reefs and marine environments.
Researchers has made a biodegradable and environmentally friendly compound called
shinorine. Look for sunscreens that are biodegradable, which are eco-friendly and break
down naturally in the environment. Zinc oxide and titanium oxide are examples of
sunscreen ingredients that are biodegradable.
No sunscreen inside the car?
False, your side and rear windows are generally only made from a single-pane glass,
which only blocks out UVB rays and still lets UVA rays through.
UVA rays are associated with premature ageing and skin cancer. Even when you are on
the road, don’t forget your sun protection.
Higher SPF indicates longer protection?
False. SPF stands for Sun Protection Factor, it refers to sunscreen’s ability to shield your
skin from the sun’s ultraviolet rays. It is a measure of the time it would take for a person
to start getting red if he or she apply the sunscreen as directed compared to the amount
of time without sunscreen.
Another example, if you burn after 10 minutes of sun exposure, an SPF of 15 will allow
you to be in the sun for up to 150 minutes without burning.
For example, SPF 15 (offering more protection than naturally dark skin) blocks out only
93% of sunburn causing UVB rays.
An SPF of 30 blocks 96.7% of UVB rays while an SPF of 50 blocks 98% of UVB rays.
or another way of looking at it is:
• SPF 15 (93% protection) allows 7 out of 100 photons through
• SPF 30 (97% protection) allows 3 out of 100 photons through.
Sunscreen in infants
Sunscreen should be avoided altogether in infants younger than 6 months old.
Sunscreen and Vitamin D
When it comes to vitamin D, even when you wear sunscreen, you are still getting an
adequate amount of sunlight to aid with vitamin D conversion.” Sunscreen still lets in the
good stuff — like vitamin D from the sun — it just blocks the dangerous UV radiation.
Safe Sun Time, which depends on the UV index in their environment, as well as their skin
type and whether they have applied sunscreen.
