What most people don’t know is that skin covered in clothing can get sunburn. Dawn Davis, a dermatologist at the Mayo Clinic, says particular types of clothing can protect you. The clothing industry has made it possible to integrate woven microfibres into specific garments with a UPF (UV protection factor) equivalent to the SPF.
Chemical sunscreens can limit sun damage by using different chemicals, says Stanley Kovak, M.D., a cosmetic doctor, and owner of the Kovak Cosmetics Center in Chicago. Those with sensitive skin should choose physical or mineral sunscreen, says Emily Smith, a dermatologist at the University of Missouri Health Care. Physical sunscreen consists of zinc oxide and titanium dioxide to protect the skin, but these chemicals don’t burn or sting the eyes, she says.
Use sunscreen on any skin surface exposed to the sun, such as the neck, feet, ears, and head. Apply a generous amount of sunscreen to dry skin for about 15 minutes before you go outside. Use sunscreen all year round, but don’t let products lull you into a false sense of safety from the sun.
There is no scientific evidence of the benefits of the use of sunscreen to minimise the long-term and short-term damage to the skin from the sun rays. And claims that sunscreens are toxic or a threat to human health are not proven. For questions about the safety of sunscreens, Dustin J. Mullens, a dermatologist in Scottsdale, Arizona, advises you to take a look at the Environmental Working Groups Sunscreen Guide, which provides safety assessments for hundreds of sunscreens based on scientific information from the literature. We spoke to experts about research to clear up common confusion with sunscreen, from sun protection factor figures to skin types.
The sun protection factor (SPF) on the product label measures how well the sunscreen protects against sunburn caused by UVA and UVB radiation from the sun. The SPF measures how much solar energy is needed to cause sunburn when wearing sunscreen, compared to unprotected skin. It also explains how long it takes a person with exposed skin to burn when they are covered in sunscreen, compared to when they are not.
The SPF number is also the level of protection that a sunscreen provides against UVB rays. The intensity and wavelength distribution of UVB rays may vary depending on the day and location. A higher SPF means more protection, but the further you go outside, the smaller the difference.
SPF 15 prevents 93% of sunlight from penetrating the skin while SPF 30 prevents 97%, and SPF 50 prevents 98% of the sun from penetrating the skin. The FDA requires sunscreens with an SPF of 15 to include a warning that they protect against sunburn but not against skin cancer or ageing. With an SPF of 15%, a sunscreen can filter out 93% of UVB rays, while it filters out 97% (SPF 50) at 30%, and sunscreen at 98% has SPF 100% or 99%.
We know that most users do not use sunscreen in the concentrations tested in the laboratory. Using sunscreen in a natural environment, you will not get the level of protection higher on the list of SPFs. The sunscreen tested for SPF was sourced from a lower label.
Sunscreen contains both chemical and physical ingredients or a combination of both. Chemical-based sunscreens such as oxybenzone and avobenzone protect your skin by absorbing ultraviolet rays and converting them into thermal energy. On the other hand, physical mineral sunscreens protect you by reflecting UV radiation before they reach your skin.

From sticks and sprays to lotions and creams, here’s what you need to look out for to keep your skin protected, hydrated and healthy throughout the season. An SPF of 30 or higher refers to the level of protection that broad-spectrum, water-resistant sunscreens with this rating offer against UV-B rays that are harmful to the sun.
Isdin Eryfotona Actinica Ultralight Emulsion Sunscreen SPF 50-55 Morrill tells us that there is no reason to place mineral sunscreen over a chemical that contains oxybenzone, which can destroy coral reefs and ecosystems, according to research. He also points out that results have shown that ingredients in chemical sunscreens do not absorb well into the skin or blood.
