The sun, the skin’s best enemy.

The sun, source of heat and well-being, is essential to life. Indeed, moderate exposure promotes the synthesis of vitamin D, which is necessary for binding calcium in bone, and stimulates the secretion of melatonin which has an anti-depressive action and improves mood.

However, excessive exposure can have negative consequences for the body, and especially for the skin. Indeed, during sun exposure, the skin is affected by three different kinds of solar radiation:

UVB rays, the most energetic type of radiation, only affects the epidermis, the topmost layer of the skin. They cause erythema, more commonly known as sunburns, which take the form of skin redness and congestion. They also generate free radicals, which can damage DNA and proteins in skin cells.
UVA rays, which are less energetic, reach the dermis, which is found underneath the epidermis, and cause more long-term reactions. They contribute to premature skin ageing, known as photoageing, which takes the form of wrinkle formation, a loss of elasticity in skin tissue and the dehydration of the outer layers of the epidermis.
Infrared rays, penetrate subcutaneous tissue and worsen damage caused by UVAs and UVBs, while also causing oxidative stress.

Biologique Recherche Solar Care Trio

In order to effectively fight against all of the harmful effects of solar radiation, Biologique Recherche has developed a three-stage sun care treatment programme, suitable for all Skin Instants®:

Sun care


Preparation UVPréparation U.V

A treatment for all Skin Instants® that prepares the skin before sun exposure.
Reconditions and protects the epidermis, and stimulates natural tanning.

This formulation 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. Préparation U.V. prepares the epidermis to optimally receive solar radiation from the very first exposure.

It is recommended to exfoliate the skin before the treatment for a homogenisation of complexion and tanning. Use the adapted Lotion P50 according to the Skin Instant® to exfoliate the skin. Apply Préparation U.V. in the morning and evening on the entire face, neck and cleavage, approximately during one month before sun exposure. Massage gently until the product is fully absorbed. If needed, you can apply, right after, your usual Biologique Recherche cream.



Protection UVProtection U.V

A treatment for all Skin Instants® that protects the skin during sun exposure.
Forms a barrier that protects the skin from solar radiation.

The skin is sensitive during sun exposure. That is why exfoliating treatments are strongly discouraged. It is necessary to moisturise the epidermis, restore skin lipids and protect skin against the entire spectrum of dangerous solar radiation. Avoid skin damage by using Protection U.V daily; the formula provides a Sun Protection Factor (SPF) of 25, which is a medium-level protection against UVB, as well as high protection against UVA. This SPF is the perfect balance for tanned, yet protected skin. In addition to protecting against solar radiation, this 100% natural sunscreen cream fights other harmful effects of sun exposure, including photoageing, the appearance of pigmented spots, and DNA damage. It is also photostable and water-resistant!

Generously apply Protection U.V. to the entire face, neck and cleavage before sun exposure. If you do not apply enough product, the level of sun protection will be considerably reduced. To be well protected, reapply frequently (at least every two hours), especially after sweating, swimming, towel drying or after a long sun exposure.



Reparation UV

Réparation U.V

A treatment for all Skin Instants® that repairs the skin after sun exposure.
Soothes, repairs and hydrates the skin.

A complex treatment formula rich in active ingredients to soothe and regenerate skin following exposure while slowing down the signs of ageing. After sun exposure, skin can be subject to an inflammatory reaction, redden, swell and become painful. The cells of the epidermis go into apoptosis, die off rapidly and get removed by desquamation. Burned skin becomes more sensitive to the sun, since the UVB rays alter the DNA of the cells of the epidermis. The skin thus needs to be soothed after prolonged sun exposure. During exposure to UVAs (which represent 98% of UV rays on the Earth’s surface), free radicals can also be formed, which modify the DNA of the cells of the dermis, altering collagen and elastin fibres. The glycation, in which these fibres become rigid and lose their visco-elastic properties, causes the appearance of wrinkles or the intensification of wrinkles that are already present. This phenomenon, which results from a reaction between the skin’s proteins (collagen and elastin) and sugars, thus accelerates skin ageing. Carnosine, which is found in the Reparation U.V., takes the place of the protein and reacts with sugar, so that the collagen and elastin fibres are protected.

After repeated sun exposures, the skin gets thicker to protect itself against UV. Moreover, cutaneous imperfections can appear. To fix this, and according to the state of the skin, it is necessary to exfoliate the epidermis with the adapted Lotion P50 to your Skin Instant® to improve its regeneration. In cure after a long period of sun exposure and the evening after the sun exposure, apply the cream Réparation U.V. to the entire face, neck and cleavage. Massage gently until the product is fully absorbed.
