tan control
Tan refers to the darkening of the skin that occurs when melanin, the pigment responsible for skin colon, increases in response to exposure to ultraviolet (UV) radiation from the sun or artificial sources such as tanning beds. Tanning is the body’s natural defense mechanism to protect the skin from UV damage, as melanin absorbs and scatters UV radiation, preventing it from penetrating deeper into the skin layers where it can cause DNA damage and increase the risk of skin cancer.
There are two main types of tanning:
Natural tanning
This occurs when the skin is exposed to sunlight or UV radiation from the sun. When the skin is exposed to UV rays, melanocytes in the skin's epidermis produce more melanin, causing the skin to darken in colour. Natural tanning can vary in intensity depending on factors such as skin type, UV exposure, and melanin production.
Artificial tanning
This involves using tanning beds or sunlamps to achieve a tan artificially. Tanning beds emit UV radiation similar to sunlight, which stimulates melanin production in the skin. However, artificial tanning carries similar risks to natural tanning, including sunburn, premature skin aging, and an increased risk of skin cancer.
While some people may seek a tan for cosmetic reasons or to achieve a “sun-kissed” appearance, it’s important to practice sun safety and protect the skin from excessive UV exposure to reduce the risk of skin damage and skin cancer.
Here are some tips for safe sun exposure:
Use sunscreen
Apply a broad-spectrum sunscreen with a sun protection factor (SPF) of 30 or higher to all exposed skin, and reapply every two hours or after swimming or sweating. Choose a sunscreen that offers protection against both UVA and UVB rays.
Seek shade
Limit time spent in direct sunlight, especially during peak UV hours (usually between 10 a.m. and 4 p.m.). Seek shade under trees, umbrellas, or awnings when outdoors.
Wear protective clothing
Cover up with lightweight, long-sleeved shirts, pants, hats, and sunglasses to protect your skin and eyes from UV radiation. Look for clothing with a tight weave or UPF (ultraviolet protection factor) rating for added sun protection.
Avoid tanning beds
Limit or avoid the use of tanning beds and sunlamps, as they emit harmful UV radiation that can increase the risk of skin cancer and accelerate skin aging.
Monitor moles and changes in the skin
Perform regular skin self-exams to check for any changes in moles, freckles, or other skin lesions. See a skin care specialist if you notice any new or changing spots on your skin.
