Sunscreen lotions and Sunblocks

UV Radiation and Wrinkles :Both UVA and UVB radiation cause wrinkles by breaking down collagen, creating free radicals, and inhibiting the natural repair mechanisms of the skin.

UVA (aging) rays cause most wrinkles,
UVB (burning) rays are the main cause for sunburns and skin cancer.

The proper use of sunscreen to block both UVA and UVB radiation is important to prevent wrinkles and premature ageing.

Sunblocks
Titanium dioxide or zinc oxide as natural Sunblocks —

• Occurring naturally , these substances are used chiefly as a white pigment and as an opacifier.
• It reflects light, so can be considered a natural sun block.
• It forms an immediate physical sun block by sitting on top of your skin.
• It reflects UVA and UVB rays away from your skin, as soon as it's applied.

Sunscreen lotions

In chemical sunscreens,

• there are some chemicals that pose potential human health risks including benzophenone, octinoxate, octylmethoxycinnamate (OMC), and oxybenzone.
• These chemicals can seep into your skin, potentially altering how your body processes the sun's rays and could upset your body's normal hormone balance.
• Chemical sunscreens need time — up to 30 minutes — to absorb into your skin to be effective.
• chemicals found in most sunscreens are not biodegradable and may have damaging environmental effects in the water. By using natural ingredients instead, keep both you and the environment safe.
