A sun care product is a preparation (e.g. a cream, oil or lotion) formulated for direct application to the skin. Its specific or primary aim is to protect skin against the sun by absorbing, dispersing or reflecting UV rays
What does a tube of Avène sun cream contain?
Sensitive skin specialists at Avène Dermatological Laboratories have poured their knowledge
and expertise into producing high quality sun protection that offers efficacy,
skin tolerance and also cosmetic appeal.
A UV filter is an organic or mineral compound that absorbs or reflects UV rays emitted by the sun to protect the skin from their harmful effects.
These include various agents that give the product its specific consistency.
These are molecules that prevent the skin from dehydrating by maintaining a healthy natural film.
Thanks to its soothing and anti-irritating properties, Avène Thermal Spring Water calms ravaged skin.
AVENE sun protection
Avène photoprotective products offer effective, broad-spectrum protection thanks to an exclusive triple complex of active ingredients: SunSitive® protection, a product of Pierre Fabre Research.
Broad-spectrum UVB-UVA protection Photostable, water resistant
Long-lasting release, photostable
Rich in Avène
Thermal Spring Water
with lasting stability and efficacy, offering the best short
and long UVB-UVA protection.
Anti-free radical protection
Solar radiation generates free radicals which
are responsible for damaging the skin.
Pre-tocopheryl (a powerful anti-oxidant and precursor of extended-release vitamin E), captures free radicals and protects the skin from oxidative stress.
The benefits of pre-tocopheryl
Acts at the heart of the cell
Transforms into Vitamin E in cells
Long-lasting release depending on the skin's needs
rich in Avène Thermal Spring Water
A number of studies conducted on Avène Thermal Spring Water have produced remarkable results that have been published in international scientific journals:
- - Respects the physiology of sensitive skin: the skin's balance is maintained.
- - Reduces the skin's reactivity: skin no longer reacts excessively.
- - Strengthens the cells' natural resistance: boosts skin's natural defenses.
adapted sun care products
Avène Dermatological Laboratories offer sun care products that have been adapted according to skin type and sensitivity.
All levels of sensitivity: An orange range for sensitive skin, a white range for skin.
How can you tell if a sun care product is effective?
Sun protection is a public health issue.
It requires the formulation and development of effective products guaranteed
to produce the desired effects.
Photoprotective products are subject to specific regulations which are found in most
countries around the world (Europe, United States, Japan and Canada).
1Evaluation of SPF index (UVB)
Sun care products are tested using a unique methodology recommended by international autorities.
SPF mainly concerns UVB protection. SPF is calculated by exposing healthy volunteers to artificial sources of UV light to reproduce the effects of sun exposure. The index is calculated by measuring the smallest dose of solar (or simulated) radiation needed to cause erythema 24 hours after the individual has been exposed: this is known as the Minimal Erythema Dose (MED).
The UVB protection factor is then calculated by comparing the doses of radiation required to produce pigmentation with and without sun protection
It should be noted that the SPF calculated is only a theoretical value as other parameters can also have an effect (open air application, the quantity of product applied etc.).
2Evaluation of UVA index
There are two methods for calculating the UVA protection index.
The PPD method (Persistent Pigment Darkening). The pigmentation caused by UVA radiation after 2 hours of exposure is evaluated. UVA protection factor is calculated by comparing the doses of radiation required to produce pigmentation with and without sun protection.
The second method is an in-vitro test based on measuring the penetration of UVA through a sun care product applied to a tray before and after exposure to a dose of UVA radiation.
The European Commission prefers the in-vitro method which produces equivalent results.
Sun care products must respect a ratio: SPF/UVA index
3Evaluation of water resistance
Water resistance is an important factor when it comes to choosing sun protection.
It is evaluated using a standardized method based on comparing SPF before bathing and after being immersed in water for a certain length of time.
- Determining the initial SPF.
- Immersion in a swimming pool for 20 minutes at a temperature of 23-32°C. This is repeated 2 or 4 times with 15 minutes' drying time in between sessions. No UV exposure.
- Exposure of the area tested and protected areas that were not tested
- Calculation of the results in terms of the percentage of initial SPF preserved
› SPF > 50% after 2 immersions: «water resistant» product.
Avène sun care products are proven to protect against damage caused by the sun's rays (DNA lesions, apoptosis of keratinocytes, cytotoxicity etc.).
The exclusive combination of active ingredients forms a unique complex composed of a minimum of UV filters with lasting stability, a powerful anti-oxidant and Avène Thermal Spring Water. This complex protects against UVA and UVB rays effectively.
