Biotherm Biosource Purifying Foaming Cleanser Anti-Pollution
Biotherm Biosource Purifying Foaming Cleanser Anti-Pollution is designed as a deep-cleansing solution to combat the daily buildup of urban pollutants. This creamy cleanser transforms into a rich foam, utilizing the detoxifying properties of Montmorillonite (French clay) to lift dirt and excess sebum from the skin surface. Infused with Glycerin, it aims to maintain hydration levels while providing a refreshing, ultra-clean feel. The formula relies on a blend of saturated fatty acids to achieve its signature dense lather, which is characteristic of traditional high-performance foaming cleansers. While it excels at removing grime and environmental debris, the inclusion of several ingredients with high comedogenic ratings gives it a specific profile that users with reactive or congestion-prone skin should note. It is a popular choice for those seeking a 'squeaky clean' finish after a long day in the city, but the complex ingredient list requires a closer look for anyone managing active acne or chronic pore blockages.
Our Analysis
Our analysis classifies this Biotherm cleanser as having a High Comedogenic Risk. The formula contains a concentrated combination of fatty acids, notably Lauric Acid (rated 4/5) and Myristic Acid (rated 3/5). While these ingredients create a luxurious foam and effective cleansing action, they are highly problematic for oily and acne-prone skin due to their molecular structure, which can easily clog pores. Additionally, Palmitic and Stearic acids add to the risk of congestion. For those prone to breakouts, these ingredients may trigger new blemishes or follicular irritation despite the purifying claims of the product.
Skin Type Recommendations
This cleanser is best suited for normal or resilient oily skin types that are not prone to acne. Due to the high risk of pore-clogging ingredients like Lauric Acid, we strongly recommend that those with acne-prone, sensitive, or combination-congested skin avoid this product to prevent further breakouts.
