What sun care advice should you pass on to your clients?

With the warmer months approaching, it’s time again to focus on the vital importance of protecting the skin from the sun’s harsh rays

The two main types of UV filter are chemical and physical/mineral sunscreens.

Says Dr Emma Meredith, director general at the Cosmetic, Toiletry & Perfumery Association (CTPA): “The most commonly used are the absorbers (organic or chemical UV filters) because these are more efficient. In organic or physical UV filters (also referred to as mineral), they act by reflecting or blocking the sun’s rays. Often both types of UV filter are used in combination because they tend to be effective against different UV light wavelengths. This means they provide a broad spectrum of protection across the whole range of UV light.”

Holistic aesthetic doctor Dr Rabia Malik adds: “Organic filters are essentially chemicals that are carbon based and absorb UV rays, protecting the skin by intercepting the rays before they can penetrate.”

Dr Preema Vig, who runs Dr Preema London Clinic, notes that cloudy days are no excuse not to wear sun protection as the level of UV radiation is not affected by temperature, and UV rays can penetrate through thin cloud.

“In fact, patchy clouds can intensify UV levels because radiation is reflected off the cloud’s edge and then focuses on the ground,” he explains.

Beauty products with SPF

As to whether moisturisers and foundations with added SPF provide enough protection, Meredith says: “Certain products contain added protection from UV rays to help combat the rays’ anti-ageing effects, but it’s important to remember that such products are not intended to be used as primary sun protection. So, if you’re wearing these products and you’re going to spend time in the sun, then you still need to apply sunscreen. Think of applying a good teaspoonful for the face, remembering the tips of the ears and under the chin.”

But, do we all still need some unprotected sun exposure to get enough vitamin D?

“I believe that some exposure is essential to help maintain vitamin D levels, but my preference would be to keep hands, arms and legs uncovered while continuing to use sun protection on the face, neck and décolletage (if exposed),” says Malik.

She adds: “Many people still require an additional oral vitamin D supplement, and I recommend it for all patients in the autumn and winter months.”

Some ingredients in chemical sunscreens, such as oxybenzone, have been identified as hormone disruptors. Should clients be concerned? “Yes, absolutely. We should be concerned about potential hormone disruptors or synthetic oestrogens, and it is for this reason that I recommend mineral-based or physical rather than chemical sunscreens,” says Malik.

Certain PRODUCTS CONTAIN ADDED PROTECTION from UV RAYS to help COMBAT THE RAYS’ ANTI-AGEING EFFECTS, but it’s important to remember that such products are NOT INTENDED to be used as PRIMARY SUN PROTECTION.

Storage time

“Products used extensively on a beach or left open for a length of time should generally be discarded after the holiday, and clients should throw away any products that have become discoloured, have an unpleasant odour, or don’t look like they should,” advises Meredith.

“Those products with a shelf life of at least 30 months may be labelled (and sunscreens will be) with a ‘period after opening’ or ‘open jar’ symbol. This isn’t an expiry date either, but an indication that once open, the product will not deteriorate to harm health.”

Meredith continues: “Most personal care products are formulated to ensure they have a shelf-life that far exceeds the normal time it would take to use the product up. This is certainly the case for sunscreens.”

Things to look for in a product

“DNA repair enzymes are important to protect against the impact of damaging UV rays and environmental exposure that can potentially cause free radical damage,” says Malik. “Using a topical antioxidant serum in addition to a mineral-based sunscreen is a good combination.”

Vig adds: “You should always go for the highest possible protection on your face, and look for sunscreens labelled ‘broad spectrum’, as only sunscreens that protect against both UVA and UVB rays are legally allowed to use this label.”

Cutting-edge sunscreens not only protect against UVA and UVB rays, they also offer anti-ageing properties and reverse and repair DNA damage, according to Vig. She predicts we’ll see more formulas in the future that offer protection against things like thymine dimmers, “which cause the specific DNA damage that is consistent with a high cancer risk”.

She adds: “Several companies are researching formulations to improve product performance, so it works on the skin for longer without reapplying.”

Research is also being done into the impact of infrared rays on skin health, with advanced formulas already offering defence.

Does black skin need sun protection?

“There is a lack of representation in promoting the protection of skin of colour from UV exposure. The myth lies in the misconception that Black and Brown people do not need to protect their skin from the sun,” shares Shalon Burruss, founder of the Black Micropigmentation Association.

She continues: “There is no real difference in the SPF levels for people of colour. Everyone is affected by the sun. Although darker skin may not burn as easily as fairer skin, melanin-rich skin can be just as susceptible to sun damage including sunburn. It is extremely important to use sunscreen of an SPF30 or higher to protect the skin. And, it is also important that if you’re participating in any activities that cause your sun protection factor to wear off, it will need to be reapplied while remaining exposed to the sun.” https://professionalbeauty.co.uk/site/newsdetails/spfs-myth-busting-and-expert-advice

YOU SHOULD always GO FOR the HIGHEST POSSIBLE PROTECTION on YOUR FACE, and look for SUNSCREENS LABELLED ‘BROAD SPECTRUM’, as only sunscreens that protect against BOTH UVA and UVB RAYS are LEGALLY ALLOWED to use this label.
