Prof. Christine Lang reports on the microbiome’s importance and mechanism of action
Munich, 26 November 2021 – What is the skin microbiome, and how can we strengthen and grow it? Professor Dr Christine Lang, microbiologist at TU Berlin and BELANO medical AG’s Chief Scientific Officer covered these issues in her presentations at the international trade fair Cosmetics Business in Munich. The lectures are now available online at https://www.youtube.com/watch?v=OVgTVHAxGSk&t=13s and https://www.youtube.com/watch?v=gfcmasDbYRg&t=1s.
Professor Lang emphasised: “When we talk about the skin microbiome, we talk about the sum total of all bacteria, fungi, and viruses which populate our skin.” Most of these microorganisms were harmless or even useful for a healthy skin. “They are also important for the skin’s appearance, an aspect we scientists only realised during the past decade, having turned our backs on it previously”, Professor Lang continued.
Key Bacterium for Healthy Skin
And yet the skin contained many commensal bacteria which mattered for a healthy skin. As one example for these key bacteria, Staphylococcus epidermidis was active against pathogen inflammatory bacteria. In addition, it supported the healing of injured skin areas and had an inhibitory effect on tumour cells in the skin (white or light skin cancer).
There was hence no way around seeing the microbiome as part and parcel of the philosophy of every good skincare. Many cosmetics and skincare products remained a long way from this development. BELANO medical examined several conventional skin lotions in the laboratory and found that many lotions inhibit the growth of healthy bacteria on the skin, or even kill them off. “Skincare lotions such as these are able to disbalance the microbiome, and with this the healthy skin flora”, emphasised Professor Lang. “From now on, however, we have to pay far more attention to making sure that skincare or cosmetic products strengthen or protect the skin’s microbiome.”
Clinical Studies Demonstrate Skin Health Improvement
A healthy skin microbiome and the associated diversity of healthy bacteria such as the key bacterium S. epidermidis are able to eliminate inflammatory bacteria, e.g. Staphylococcus aureus which is present in high concentrations in atopic eczema and other skin diseases. Hence, the aim was to stabilise the microbiome. To do so, BELANO medical identified from a large number of bacterial strains a lactic acid bacterium which had exactly this stabilising effect.
In clinical studies and in collaboration with dermatologists, the ingredient was tested on people suffering from very dry skin, acne, dermatitis, and contact allergic dermatitis, and improved skin health significantly. “There is such a striking visible difference that even as a microbiologist I find myself impressed”, emphasised Christine Lang in her lectures. This effect also made it possible to regenerate the skin microbiome and return it to a medical condition, i.e. turning diseased skin back into healthy skin. “There is always a seamless transition from normal skin to stressed skin to abnormal and diseased skin”, Professor Lang continues.
Natural Ingredient as a Ferment of Lactic Acid Bacteria
Using appropriate microbiotic cosmetics or medical skincare could also help to prevent or reduce skin ageing. “Some bacteria play a key role in skin regeneration, they deliver crucial signals into the skin”, explains Christine Lang in her lectures. The identified microbiotic ingredient, prepared as a ferment of lactic acid bacteria, offered a natural way of stimulating the growth of these positive, healthy bacteria. “This strain of lactic acid bacteria does not affect S. aureus directly, we rely on Nature instead. We initiate the natural, healthy cycle.”
BELANO medical launched this microbiotic ingredient with its “ibiotics” range of cosmetics and the “ibiotics med” range of medical skincare. It is available to consumers through both direct distribution and retail sales, and is offered in private labels and as bulk ware. Development and manufacturing do not involve animal testing or animal inputs.
