WHAT CAUSES THE SKIN TO TAN?

Tanning is the skin’s response to harmful UV radiation. While sun exposure can play a role in the production of vitamin D, an essential nutrient for our bodies, exposing your skin to UV radiation unprotected is never a “healthy” choice. Even shorter periods of sun exposure can have short-term adverse effects, but when you regularly tan, from the sun or through tanning beds, it has an accumulative effect on the skin that can cause more serious risks.

WHAT ARE THE EFFECTS OF UV EXPOSURE ON YOUR SKIN?

In addition to temporary sunburn that causes redness and discomfort, there are a number of risks to prolonged, frequent exposure to UVA and UVB radiation.

Compromised moisture barrier

UV rays directly affect the skin’s protective moisture barrier, which leaves your skin more sensitive and exposed to environmental aggressors like pollution and free radicals. This can translate to a range of skin concerns, including sensitivity, dryness and redness.

Photoageing

UV radiation significantly impairs collagen production and accelerates the breakdown of existing collagen and elastin fibres in the skin. These fibres are responsible for the skin’s firmness and elasticity, and UVA rays penetrate deep into the dermis generating free radicals that affect their structural integrity. When this occurs frequently, the skin struggles to keep up with new collagen and elastin production, leading to a loss of skin elasticity and the formation of fine lines and wrinkles. Premature ageing caused by UV radiation and free radicals is referred to as photoageing. Regularly exposure to UV radiation.

Skin cancer

One of the most serious risks that comes with tanning. UV radiation affects the DNA within the skin cells which disrupts normal cell growth and development. Over time this contributes to the formation of skin cancers like melanoma, basal cell carcinoma, and squamous cell carcinoma. The more you tan and expose yourself to UV radiation, the higher the risk of skin cancer.

Why tanning in Australia is particularly dangerous

Tanning is not recommended in any part of the globe, but tanning under the harsh Australian sun is even riskier. Australia’s clearer atmospheric conditions, proximity to the equator and the globe’s elliptical orbit mean that Australia is exposed to much higher levels of UV radiation, increasing the risk of skin cancer formation. This is why it’s even more critical that you protect your skin with sunscreen every day, even on cold or cloudy days.

There’s nothing healthy about a tan

Always prioritise sun safety your skin’s condition by protecting it against UV radiation. Though you might be tempted to encourage a “natural glow” with frequent UV radiation, the long-term risks far outweigh the apparent benefits, especially if you have lighter or pale skin. Protect your skin every day by practicing the 5 S’s of sun protection:

1. Slip on a shirt and other sun protective clothing.
2. Slop on some sunscreen. Look for high SPF, broad spectrum formulas.
3. Slap on a broad-brimmed hat.
4. Seek shade as much as possible, avoiding peak UV hours between 10am and 4pm.
5. Slide on some sunglasses to protect your eyes.
