Review : Bioderma Photoderm SPF30 Mattifying Sun Fluid





Product Description
The high anti-UVB efficacy and unmatched anti-UVA performance of Photoderm AKN Matsafely protect against sunburn.
A major advance against risks of cell damage, its exclusive patented Cellular BIOprotection® complex* provides optimum protection for the skin cells.

The sebo-regulating Fluidactiv® complex*, a BIODERMA innovation, improves sebum quality and helps to keep the skin clear and healthy. Photoderm AKN Mat guarantees a long-term matifying effect. Colourless when applied, Photoderm AKN Mat leaves no oily film and no white marks. Photoderm AKN Mat guarantees excellent tolerance. It is non-comedogenic and photostable.

I owned a 15ml sized sample which I brought it along for my Hainan trip. Recommended for oily or combination skin, the texture of this sun fluid is not really fluid-like texture despite the name claims.
White in colour, it is thick and creamy. I used it for the hands and neck, rather than the face, since it looks like it could clog my pores. It has a distinct sunscreen scent as well.

In terms of sunscreen ingredients, 
Octocrylene protects against partial UVA and full UVB rays
Methylene Bis-Benzotriazolyl Tetramethylbutylphenol is an organic compound that absorbs ultraviolet (UV) light.(source )
Butyl Methoxydibenzoylmethane ( also known as avobenzone ) protects against full UVA and partial UVB rays


Octocrylene
According to TIA, Octocrylene can penetrate into the skin and act as a photosensitizer, resulting in an increased production of free radicals. Free radicals can induce indirect DNA damage and potentially contribute to the increased incidence of malignant melanoma in sunscreen-users. Maximum recommended by FDA is 3%. You can also read more about it in EWG.
According to this source, Octocrylene appears to be a strong allergen leading to contact dermatitis in children and mostly photoallergic contact dermatitis in adults with an often-associated history of photoallergy from ketoprofen. Patients with photoallergy from ketoprofen frequently have positive photopatch test reactions to octocrylene. These patients need to be informed of sunscreen products not containing octocrylene, benzophenone-3, or fragrances


Avobenzone
According to this source, tests have revealed Avobenzone’s tendency to significantly degrade in light over time, lessening its sun protection capabilities. For this reason, most sunscreens containing the ingredient also include photo-stabilizing ingredients like octocrylene.
Avobenzone appears to be relatively non-toxic and non-irritating to the skin. However, because it is often used in conjunction with photo-stabilizers, there is a greater risk for skin irritation and low-level toxicity. Furthermore, some studies have demonstrated it to be absorbed by the body and secreted into urine, and is therefore not recommended to use on children or pregnant women
