What is the best sunscreen for sensitive skin?

Some sunscreens can cause unpleasant stinging sensations on sensitive skin. Opt for broad-spectrum UVA-UVB protection that is tested on the most sensitive skin, such as the ANTHELIOS range from the sensitive skin specialist brand La Roche-Posay. All ANTHELIOS products integrate naturally anti-inflammatory and anti-oxidant La Roche-Posay Thermal Spring Water to soothe sensitive skin.

How can I protect my skin from the sun?

Sun exposure puts you at risk of sunburn, as well as the long-term dangers of premature ageing and skin cancer. To stay safe in the sun, seek shade between 11 am and 3 pm, wear a hat, protective clothing and sunglasses. In addition to these measures, generously apply broad-spectrum UVA-UVB sunscreen every 2 hours to any area of exposed skin.

What is sunscreen SPF?

SPF stands for “sun protection factor”. It relates to your sunscreen’s ability to protect skin against UVB rays which cause burning. The higher the number, the greater the protection. When in the sun, you are recommended to apply a minimum of SPF 30 every 2 hours. A golfball-sized amount is required for the whole body.

How can I protect my skin from the sun without sunscreen?

Dermatologists recommend wearing hats, sunglasses and protective clothing as well as seeking shade when the sun is at its strongest. But sunscreen is at the core of sun protection strategies and cannot be omitted from your routine. ANTHELIOS sunscreens undergo rigorous testing on even the most sensitive skin to ensure total safety.

Which sunscreen is safe for coral reefs?

Both of the primary filters in La Roche-Posay’s ANTHELIOS range, Mexoryl SX and Mexoryl XL, have been extensively tested with regard to marine environments. In ecotoxicology testing, 5 weeks’ exposure to these filters at concentrations higher than those found in sea water neither induced coral bleaching nor had any negative effect on the coral’s symbiotic micro-algae.

DARK CLOTHES ARE
BETTER-SUITED FOR THE SUN.

TRUE

Indeed, dark and intense colours such as black, navy, red, or emerald green, provide more UV protection than white and pastels. So make sure you bring along some dark colours items of clothing too when packing for your next holidays!

VULNERABLE TO THE SUN.

SUN IS GOOD
FOR YOUR KID.

FALSE

Children's skin is particularly vulnerable to the harmful effects of the sun. That's why paediatricians and dermatologists agree that babies and toddlers under 3 years old should have no direct sun exposure whatsoever. After this age, make sure you use a high-protection broad-spectrum UVA-UVB sunscreen like Anthelios.

SUN SENSITIVITY AND SUN REACTIONS
SUN ALLERGIES

This is called photosensitivity and can arise for a variety of reasons:

  • Sun allergy, or “polymorphous light eruption,” where the skin breaks out in annoyingly itchy red bumps following sun exposure;
  • Skin with a very fair phototype (skin tone), where the skin tends to burn with even mild sun exposure (red heads with freckles and blue eyes are particularly vulnerable)
  •  Certain ingredients in skincare products such as AHAs, retinol and benzoyl peroxide can make the skin ultra-sensitive to UV, resulting in rashes following exposure;
  • Some medications taken by mouth, especially tetracycline antibiotics and the acne drug isotretinoin (Accutane), can cause sudden swelling or irritation in response to sun exposure;
  • Skin with underlying problems such as eczema, acne or rosacea can be aggravated by the drying effect of the sun;
  • Some cancer treatments cause the skin to be more sensitive to sunlight. Exposure to ultraviolet (UV) radiation puts you at risk for very intense sunburns, so it is generally advised to avoid any sun exposure. You should be even more careful if you are undergoing radiation therapy, as chronic radiodermatitis may occur, in some cases even several years after your treatment.
  • Certain pre-existing medical conditions such as lupus can make skin photosensitive and break out in rashes following UV exposure.

SUN ALLERGY OR PHOTOSENSITIVITY?
PREVENTION IS KEY

In all cases of sun allergy or photosensitivity, whatever the cause, your buzzword is prevention and following a few simple steps can make all the difference.

Particularly in spring and summer, wear protective clothing (hat, long-sleeved shirt etc.). Always choose a broad-spectrum sunscreen with ideally an SPF of 50+ and apply it to any areas of exposed skin. Avoid exposure when the sun is at its strongest between 10 am and 4 pm.

In this subsection, you will find a comprehensive guide to sun allergy, also known as polymorphous light eruption or benign summer light eruption, with crucial tips on how to avoid those annoyingly itchy summer rashes.

You’ll also find useful information on photosensitising medications and how to care for your skin if you are taking them.
