PREPARE your skin for the sun

At least a month before being exposed to the sun, we recommend that you start preparing your skin by promoting melanin synthesis which will stimulate natural tanning and avoid burns as well as sun damages such as pigmentation.


1. Boost melanin

Kamilla Schaffner’s Method:

Melanin manipulation can be achieved by increasing a certain amount of nutrients in your daily nutrition. The most important nutrients in melanin production are: Vitamin D3 and Beta-carotene that includes its derivatives Lycopene, Lutein, Astaxanthin and a wide spectrum of fast-acting antioxidants. When you nutritionally combine these ingredients you can achieve what is called in Clinical Nutrition a synergistic effect which creates a perfectly healthy environment within a body to achieve a very naturally even tan, but most importantly, painless and burn-free tanning experience. If you do it early enough (I suggest 4-6 weeks before active sun exposure), you create a unique dietetic reserve of nutritional compounds that continuously prepares your body and most importantly your skin to active exposure to UVA/UVB rays.

  • Vitamin D3 rich foods are mostly eggs, milk, fish and sea food.
  • Beta-carotene rich foods are all yellow/orange/red pigmented fruits and vegetables. These include peppers, tomatoes, carrots, apricots, grapes, watermelon, papayas, oranges, squashes, pumpkin, sweet potatoes, spinach, turmeric, raspberries, strawberries, red currants, rosehips.

Biologique Recherche’s Method:

The sun, essential for life, emits various rays. UVA and UVB are the two types of UV rays that are not filtered out by the planet’s ozone layer and so reach the skin tissue. UVB are absorbed by the epidermis, whereas UVA penetrate deeper into the dermis.

Moderate exposure to sunlight has health benefits, improves mood, and also synthesises vitamin D which is essential for binding calcium in bone, but excessive exposure causes skin damage. Melanin, responsible for skin coloration, also provides natural skin protection. Light skin is therefore more sensitive to sun that dark or olive skin. This is why the skin changes colour when exposed to UV rays. Melanin synthesis is one of the body’s defence mechanisms against aggression from UV rays by allowing the skin to absorb part of it. Before prolonged exposure, the skin contains little melanin and cannot defend itself much against the sun’s rays.

The melanogenesis principle (melanin production):

Melanin is produced by dendritic cells called melanocytes; which are present in the basal layer of the epidermis and are surrounded by keratinocytes. Triggers such as UV rays induce the melanin production mechanism:

UV rays stimulate the synthesis of the hormone α-MSH and other messengers such as endothelin and phyto-endorphins, which activate tyrosinase – a key enzyme in melanogenesis that turns tyrosine into melanin. The resulting melanin is stored in vesicles called melanosomes. These melanosomes migrate through the dendrites (along the “arms” of the melanocytes) into the keratinocytes where they release the melanin.

As part of the cell renewal process, keratinocytes rise to the surface along with the melanin. Once released in the keratinocytes, the melanin absorbs and reflects part of the solar rays (UV in particular) that have penetrated the corneal layer. It thus prevents these rays from damaging DNA and protects the nucleus of the keratinocytes and other skin cells.

Biologique Recherche’s Préparation U.V. stimulates natural tanning and prepares skin for exposure to sun by boosting melanin synthesis without exposure to ultraviolet. It thus prevents UV rays from damaging DNA and protects the nucleus of the keratinocytes and other skin cells.

2. Prevent pigmentation

Kamilla Schaffner’s Method:

The next important step in preparing your skin for prolonged sun exposure is to prevent appearance of hyper-pigmentation (also known as ‘liver spots’) that so many women are prone to due to fluctuating hormonal status. This can be achieved by combining nutritional seaweed into your diet on a daily basis prior to sun exposure. Sea weed acts as a metabolic booster, in particular of liver function, which assists in processing and taking out of the system hormonal excess responsible for appearance of hyper-pigmentation.

Biologique Recherche’s Method:

The earliest and most common warning of a change in the skin’s capacity to repair itself is the appearance of pigmented spots, linked to the accumulation of lipofuscin and melanin. Lipofuscin is a yellowish brown pigment created by the oxidisation of proteins and lipids and is present in all cells. There are various naturally occurring species in the body that can combat lipofuscin; 1/ Proteasome, an enzyme complex located in cells that degrades and naturally recycles damaged and oxidised proteins, promoting the elimination of lipofuscin. 2/ Antioxidants, naturally present in the body, which limit oxidation and those proteins and lipids. With age, proteasome activity slows down and its functioning is affected by UV rays. Additionally, oxidative stress increases while the antioxidant system weakens. Consequently, lipofuscin gradually accumulates. This phenomenon, coupled with an abnormal local accumulation of melanocytes, causes pigmented spots to appear.

Biologique Recherche’s Préparation U.V. helps prevent the appearance of pigmented spots and slows skin ageing, by stimulating proteasome activity and reducing the rate of protein oxidation.

3. Prevent skin ageing

Kamilla Schaffner’s Method:

Lastly, in order to maximise lasting dermal protection and hinder photoageing, it is important to have a high antioxidant status particularly of dermal tissue. The simplest way to ensure that is to consume high-antioxidant teas like matcha green tea/rosehip tea/white tea or raw fresh herbs like thyme, rosemary, parsley, coriander. The green pigment (chlorophyll) will ensure all tissues within a body including dermis are protected against natural and environmental oxidation and damage. 

Biologique Recherche’s Method:

Sun exposure also stimulates the formation of free radicals, DNA changes, and skin aging. Free radicals are considered to be one of the causes of tissue ageing, and the appearance of wrinkles in particular. It accelerates the degradation of collagen and elastin, and is associated with sun-induced epidermal dehydration, skin damage, and more prominent wrinkles.

Biologique Recherche’s Préparation U.V. helps combat the harmful effects of UV on the skin leading to photoageing. It has a preventive action on the formation of free radicals and promotes DNA repair thanks to ingredients packed full with antioxidants such as tripeptides and rosemary oil extract.

Préparation U.V. is rich in natural and plant-based active ingredients, stimulates natural tanning and prepares skin for exposure to sun. It thus boosts melanin synthesis without exposure to ultraviolet. It helps prevent the appearance of pigmented spots and slows skin ageing, by stimulating proteasome activity and reducing the rate of protein oxidation. Its anti-radical function also fights free radicals. This treatment is recommended for all Skin Instants®.

The benefits:

  • Prepares skin for sun exposure.
  • Promotes melanin synthesis, thereby stimulating natural tanning without suffering the harmful effects of solar radiation.
  • Protects against free radicals.
  • Prevents the appearance of dark spots and slows skin ageing.
