Sunscreen is generally considered safe when used as directed. Sunscreens work by using ingredients that absorb, reflect, or scatter the sun's harmful ultraviolet (UV) rays.
Types of sunscreens
There are two types of UV rays: UVA and UVB. UVA rays are the most common and can penetrate deep into the skin, leading to premature aging and skin cancer. UVB rays are the main cause of sunburn and can also cause skin cancer. Sunscreen can help protect the skin from the damaging effects of UV radiation by absorbing or reflecting these rays.
It's important to choose a sunscreen that is appropriate for your skin type and the conditions in which you will be using it. Sunscreens are available in a range of formulations, including lotions, creams, gels, and sprays. It's also important to follow the instructions on the label, such as applying the sunscreen liberally and evenly, and re-applying it every two hours or after swimming or sweating.
It's worth noting that some people may have allergies or sensitivities to certain sunscreen ingredients. If you experience any irritation or other adverse reactions after using a sunscreen, stop using it and consult a healthcare provider.
Without a doubt we know that excess ultraviolet light exposure certainly is not safe or healthy for the skin and has been shown to increase your risk of all types of skin cancer.
Benefits of sunscreen
Sunscreen can help reduce the risk of skin cancer by protecting the skin from the harmful effects of ultraviolet (UV) radiation. UV radiation is a type of energy emitted by the sun that can damage the skin and increase the risk of skin cancer. There are two types of UV radiation: UVA and UVB. UVA rays are the most common and can penetrate deep into the skin, leading to premature aging and skin cancer. UVB rays are the main cause of sunburn and can also cause skin cancer.
Sunscreen is a vital tool in the prevention of melanoma, a type of skin cancer that can be deadly if not caught early. According to the World Health Organization, melanoma is the fifth most common cancer globally, with an estimated 232,000 new cases annually. It is caused by overexposure to ultraviolet (UV) radiation from the sun or artificial sources such as tanning beds.
There is strong evidence that sunscreen can help reduce the risk of melanoma. A review of nine studies involving more than 400,000 participants found that consistent sunscreen use was associated with a 30% reduction in the risk of melanoma (Autier, Dore, & Schepp, 2012). Another study of over 1,600 Australian adults found that those who regularly used sunscreen had a 50% lower risk of developing melanoma than those who did not use sunscreen (Green, Williams, & Neale, 2006).
It's important to note that sunscreen alone is not a guarantee against skin cancer. It is just one part of a comprehensive sun safety plan. It's also important to regularly check your skin for any changes or abnormalities and to see a dermatologist if you notice anything unusual.
