There are several parameters indicative of the integrity of the skin barrier, and among them transepidermal water-loss (TEWL) is considered one of the most important. It is defined as the flux density of water diffusing from the dermis and epidermis through the stratum corneum to the skin surface. Increased TEWL levels are associated with alterations of the skin barrier [ 7]. Stratum-corneum hydration (SCH) is another important parameter for assessing the barrier function of the skin. It shows the water content of the stratum corneum, and low SCH values are often associated with dermatological conditions and increased disease severity. Other skin characteristics related to skin-barrier function are pH, elasticity, temperature, melanin and the erythema index [ 8, 9, 10, 11].

PROTECT SKIN EVEN ON CLOUDY DAYS: Daylight and sun exposure damages skin every day, all year round regardless of the weather. The effects might not be immediately apparent but daily use will help maintain skin health and prevent premature skin ageing

3 major benefits of applying a double layer of sunscreen

TRUST THE BUM. What does that mean? It means trust us, the ones who live on the beach and need products that work on even the most intense days in the sun. The simple truth is, when you make products to protect the ones you love, you make ‘em better.

If you’re going to be in and out of the water all day, however, you might find that regular top ups can be done using your body sunscreen (this is the cheaper option too!). The price point of { face sunscreens} tends to be higher and the bottles much smaller, so it isn’t necessarily worthwhile using your face SPF to top up your protection throughout the day. For the same reason, it’s not worth using your face sunscreen all over your body. Concerning the impact of sex and age, we did not observe great differences between men and women or participants of different age-groups. This fact is important so that recommendations about sunscreen regarding skin-barrier function could be spread to both sexes and different age-groups. It is important to mention that we only include adults, so further research is needed to evaluate the impact of sunscreen on children. ORIGINAL SPF 30 SUNSCREEN LOTION. This is the stuff we use every day. It’s the formula that started it all. People say it smells like summer. We like that. Whether we’re spending a lazy day at the beach or just hangin’ out, our Original formula is definitely our fav.

PROTECT YOUR SKIN. The key to practicing safe sun is to protect and moisturize your skin. Our Our Original Sunscreen line is Free From Oxybenzone and Octinoxate, and Gluten and Cruelty Free, to ensure a fun day in the sun. But of course, if you live in a warmer climate when more of your skin is exposed year round, you should apply body sunscreen every day too. How much sunscreen should you use on your body? Skin pH is another essential parameter for the evaluation of epidermal functions, as the acidic nature of pH influences skin-barrier function, lipid synthesis and aggregation, epidermal differentiation, desquamation, skin-barrier regeneration and skin antimicrobial-response [ 14, 15]. Elevated pH values are related to the loss of antimicrobial activity, and it has also been shown that, in patients with atopic dermatitis, higher values of the SCORAD index are associated with skin-barrier dysfunction, which is reflected in higher pH and temperature and lower SCH and elasticity [ 15]. In our study we observed that despite the increase in pH after the application of the sunscreen, the values remain within normal ranges, and therefore the epidermal barrier is not affected by it. SCH is another important parameter for skin integrity, and lower-than-normal values are also frequently associated with skin-barrier dysfunction. In some publications it has been observed that the face has higher hydration-indices than other anatomical regions [ 26, 27, 28]; however, there is also literature in which the measurements are reversed, and the skin of the forearm is more hydrated than that of the face [ 27]. In our case, our findings were consistent with increased facial-hydration.
