The hydrolipidic film, also known as the acid mantle, is a protective film that covers the entire surface of the skin. It is composed mainly of sweat, sebum, water and microbes. Its main function is to defend the skin against bacteria, acting as an external protective barrier. It also ensures the correct balance of the skin flora and helps the skin to maintain its suppleness and moisture.
There are more than 1000 different species of microbes just on the skin alone. An unbalanced skin microbiome can cause atopic dermatitis, acne or psoriasis.
What is the function of hydrolipidic film / microbiological barrier?
Prevent moisture loss: The skin's hydrolipidic film / microbiological barrier can be damaged or removed by using harsh cleansers, or simply with age, which can lead to transepidermal water loss. A healthy skin barrier limits moisture loss which reduces the conditions of dehydration, tightness and dry skin.
Protection from free radicals: The hydrolipidic film / microbiological barrier is a shield against free radicals. The free radicals can damage the collagen and elastin resulting in reduced skin suppleness, leading to signs of premature aging such as wrinkles and fine lines.
Defend against pathogenic bacteria: In the microbiological barrier, the skin's resident bacteria act as cleaners, preventing undesirable bacteria and fungi from developing. The hydrolipidic film (acid mantle) has a pH between 4.5 and 6.2. This plays a crucial role in the body's self-defence method, because pathogenic bacteria that become adapted to the more acidic pH of the film are then unable to survive in the more alkaline environment in our blood.
Probiotics skincare is developed based on skin microbiome science, it helps to enhance the skin's natural barrier function, fundamentally increasing the skin's defence system to fight against environmental aggressors. When the skin barrier is healthy, it will result in a hydrated stratum corneum in the epidermal layer of the skin, and your skin will look naturally glowing and radiant.
