PROTECT your skin from the sun

After introducing our collaboration with nutritionist Kamilla Schaffner and sharing nutritional tips for skin preparation pre sun exposure last week, we are about to reveal how to protect your skin from damaging UV rays whilst being exposed to sun.

During sun exposure, it is strongly recommended that you use SPF protection to create a shield against UVA and UVB rays. Truth to be told: both UVA and UVB are very dangerous rays for skin due to the fact that both are slightly different forms of radiation. Radiation is extremely damaging to one’s health. In short, UVA are more damaging due to the fact that they have ability to penetrate deeper into the dermis as opposed to UVB rays that affect only epidermis, which impart red/brown hue to the skin. This is how our skin changes pigment when exposed to the sun light (put in a very simplified way). The idea is to absolutely limit exposure to UVA and have controlled amount of UVB but know exactly what to do post-sun exposure which typically results in elevated inflammatory markers and decreased antioxidant status.

1. Counteract effects of UV rays on the skin

Kamilla Schaffner’s Method:

The best solution is to dramatically increase the most potent antioxidants in the system: Vitamin A (beta-carotene, Lutein, Lycopene – blueberries, tomatoes, carrots, pumpkins, watermelon, turmeric), Vitamin C (citrus, greens, green tea), Vitamin E (abundant in nuts and seeds) and Omega-3 and Omega-6 Essential fatty Acids (walnuts, flax seeds, oily fish) to significantly reduce inflammation post UVB exposure.

A packed-full in antioxidants dietary menu:

  • Breakfast: Iced green tea with a handful of Brazil nuts.
  • Lunch: Spinach salad with walnuts and grapefruit.
  • Snack: Raw tomato Nage with capers and green chillies.
  • Supper: Carrot soup with sesame seeds and toasted seaweed or pea shoots salad with trout and flaked almonds.
  • Drinks to include: Watermelon juice with lime and black sesame seeds sprinkle, and fresh tomato juice with lime, Tamari and a few drops of toasted sesame oil.

Biologique Recherche’s Method:

When exposed to sunshine, the skin receives rays emitted by the sun. The solar spectrum is composed of three types of rays classified by their wavelength: ultraviolet, visible light, and infrared. There are three types of UV rays: UVA, UVB, and UVC. Only the first two reach our bodies, as UVC are filtered out by the planet’s ozone layer. Depending on their wavelength, UVs penetrate the skin to a greater or lesser depth. The longer their wavelength, the deeper they penetrate. Most UVB are absorbed by the epidermis, whereas UVA penetrate to the dermis. The intensity of the sun’s rays varies depending on where you are geographically, altitude, season, time of day, weather conditions and light reflection. It also depends on the skin phenotype, as natural protection varies from person to person.

Excessive exposure is responsible for various harmful effects dangerous to health, with short-term and long-term consequences.

  • In the short term, exposure to UV causes thickening of the skin, redness, the introduction of sunburn cells, the production of free radicals (oxidative stress), DNA damage, and allergies (lucitis). All these skin afflictions are due to increased skin sensitivity to light. Erythema or sunburn, mainly caused by UVB, manifests as redness and skin congestion, corresponding to 1st or 2nd degree burns. After a few days, sunburn disappears and the skin starts to peel. This is accentuated by the formation of sunburn cells, which are apoptotic keratinocytes, i.e., dying skin cells.
  • In the long-term, exposure to ultraviolet, and UVA in particular, causes premature ageing called photoageing. This is characterised by wrinkles, loss of skin elasticity and increased sun-induced dehydration. It also encourages the development of precancerous lesions called actinic keratosis. These lesions manifest as an increase in keratin in areas exposed to the sun. A risk therefore exists of developing skin cancer, resulting from damage to DNA and the immune system. Skin carcinomas occur most frequently in adults, especially basocellular and spinocellular carcinomas. Primary cancers develop in the deepest layer of the epidermis, the basal layer, whereas secondary cancers develop in more superficial epidermal layers. Melanoma is the most dangerous form of skin cancer. In 80% of cases it manifests as pigmented spots on the skin, but its main danger is metastasis. It can propagate to other organs and spread throughout the entire body. Infrared (IR) rays penetrate into sub-cutaneous tissue and can aggravate the skin damage produced by UV. They are absorbed by the water in the skin, causing sensations of heat, from pleasant warmth to burning. They are also responsible for the introduction of oxidative stress and the formation of wrinkles.

Protection U.V. fights a number of harmful effects from sun, including photoageing. The cream contains extract of Laminaria Algae, which strengthens the hydroplipidic barrier of the epidermis and the dermal-epidermal junction. In addition to its antiradical action, the extract reduces and moisturises. Protection U.V. also contains, Silymarin, powerful antioxidants to support the antiglycation action of the carnosine in the prevention of the reticulation of elastin and collagen responsible for the loss of skin elasticity and the appearance of wrinkles.


 2. Protect the skin against UV rays

Kamilla Schaffner’s Method:

Sun protection as we know it is mostly done on the outside by applying a physical barrier. However, you can eat certain foods that will assist creating a certain amount of nutrients required for a natural synthesis of sun protecting compounds. The most important aspect in this respect is consumption of metallic minerals like iron, zinc and copper. Zinc plays the most important role in sun protection due to it being the most important co-factor for more than 300 enzymes involved in the defence against environmental and oxidative stress. Moreover, it also assists in dermal healing due to its function in increasing hydroxyl-proline in dermal abnormalities. Foods rich in zinc are: all sea food particularly oysters, prawns, scallops, as well as pumpkin (and its seeds), brewer’s yeast (think Marmite) and eggs.

Topping up on zinc for dermal sun-protective purposes is both healthy and delicious:

  • Breakfast: Chilli scrambled eggs on whole wheat toast.
  • Lunch: Garlic sautéed scallops with green and orange papaya salad.
  • Supper: Oysters or prawn tempura with crunchy Asian vegetables.

Biologique Recherche’s Method:

The body has evolved various forms of natural protection against aggression from UV rays. These include increasing the thickness of the corneal layer when exposed to sun, and surface lipids to block UVB on the outside of the skin. An enzyme-based DNA repair system also contributes, to the extent possible, to alleviate damage to genetic strands from UV rays. The skin also has components (enzymes, vitamins, trace elements, carotenoids, etc.) whose natural antioxidant power fights the formation of free radicals caused by exposure to sun. However, natural means of protection are insufficient to protect us fully against solar aggression. It only protects against low doses of UV. In such conditions, it would take approximately two to four weeks for the skin to produce the pigmentation and thickening of the corneal layer necessary for its photoprotection, which is inadequate. Consequently, under repeated or intense exposure, an external photoprotection system is necessary to limit skin damage.

Our laboratory has formulated 100% natural filters, combining non-nanoparticulate mineral filters and plant-based filters that protect against the entire spectrum of solar wavelengths that are harmful for the human body. Our product also contains an infrared filter, Extract of Pink Coralline Algae, which acts as a heat shield. This complex is called Triple Shield Complex©.

The combination of these filters gives Protection U.V. cream a solar protection factor (SPF) of 25, which is a medium-level protection against UVB, as well as high protection against UVA. This SPF permits both tanning and protection when applied regularly (every 2 hours).


3. Prevent sun spots

Kamilla Schaffner’s Method:

The next important factor is prevention of pigmentation. As discussed previously, hyper-pigmentation is 99% a result of dysfunctional liver. Therefore, the best nutritional strategy is to keep natural levels of antioxidants very high and keep your liver ‘cool’ and toxins-free. The best nutrients for this particular task are citrus family and fresh herbs: lemons, oranges, limes, grapefruit, milk thistle, nettle, sage, rosemary. All of these are extremely high in ORAC value and boost immunity and dermal protection beautifully. Liver health is largely mediated by the consumption of various sea vegetables like Dulce, Nori, Arame, Wakeme, Agar, Kombu and samphire as they help to keep your liver clean of resident toxins. Including these super-foods in your diet in conjunction with top-quality BR sun-protection will have an incredible effect.

  • Breakfast: Fresh grapefruit juice with grated turmeric.
  • Lunch: Arame salad with lime and sesame seeds dressing.
  • Supper: Miso soup with brown shrimp and toasted Nori.
  • Drinks to include: Fresh rosemary and lemon infused water, and nettle tea with orange slices.

Biologique Recherche’s Method:

Melanin the biological pigment responsible for the skin’s tan colour and its synthesis is one of the body’s defence mechanisms against aggression from UV rays by allowing the skin to absorb part of it. Lipofuscin is a yellowish brown pigment created by the oxidisation of proteins and lipids and is present in all cells. This phenomenon, coupled with an abnormal local accumulation of melanocytes, causes pigmented spots to appear.

There are various naturally occurring species in the body that can combat lipofuscin:

  • Proteasome, an enzyme complex located in cells that degrades and naturally recycles damaged and oxidised proteins, promoting the elimination of lipofuscin.
  • Antioxidants, naturally present in the body, that limit oxidation of those proteins and lipids.
