Tanning AND Mineral vs Chemical Sunscreen

Are tanning beds safer than the sun?

No. Both are harmful. UVA and UVB rays can be absorbed from the sun as well as tanning beds. It best to avoid tanning beds and wear sunscreen when you outside, otherwise it may accelerate skin aging.

What is the difference between mineral sunscreen and chemical sunscreen?

Mineral sunscreens are thicker in appearance and usually contain zinc oxide and titanium dioxide.  These sunscreens reflect UV light by blocking and scattering UV rays prior to the rays penetrating the skin. They are also known as physical blockers as they sit on top of the skin. Mineral sunscreens tend to be ideal for people with rosacea or sensitive skin. 

Chemical sunscreens are absorbed thru the skin and work by converting UV rays into heat then releasing the heat from the skin. Oxybenzone, commonly found in chemical sunscreens, is thought to be a hormone disruptor and allergen, while titanium dioxide and zinc oxide are considered safer. Hormone disruptors, also known as endocrine disruptors, are chemicals that can mimic the actions of hormones that naturally occur in the human body. 

Mineral sunscreens tend to have a longer shelf life, while chemical sunscreens are short, with an average shelf life of 3 years. Be sure to never use sunscreen beyond its expiration date as it will not have be as effective.
