Summer sun and temperatures are beloved because they provide you with
the opportunity to spend more time outdoors doing the things you love.
However, the sun and temperatures come at a price and it is your skin
that pays that price. Sun damage can lead to premature aging of the
skin, wrinkles, marks, dry skin, and even skin cancer over time. The
hottest season of the year requires careful thought for your skin even
as you enjoy the heat and freedom of summer.

Understand how the summer sun impacts your skin. It's
important to know how the sun's rays impact your skin, especially when
you're seeking to cut through the hype on cosmetic labels. The following
basics should assist your understanding:[1]
- Ultraviolet A (UVA): The longest wavelength of the sun, this one penetrates the dermis, your skin's deepest layer. Sun damage can activate free radicals and promote skin aging.
- Ultraviolet B (UVB): This wavelength penetrates the skin's upper layer, the epidermis. These rays cause sunburn, allergic reactions and skin cancers. After six times of being burned, the skin has double the risk of developing a fatal melanoma.[2]
- Ultraviolet C (UVC): Generally these rays are filtered by the ozone layer and they're the most damaging rays.
- Scratch Test (ST): Sometimes if you scratch your skin with a back of your heel, the test will reveal your sensitivity.
- Infra-red (IR): This is the "heat" from the sun and too much can negatively impact collagen, elastic and your immune system.
