Prebiotics, known especially for their ability to regulate intestinal flora, also play an important role in skin health, particularly in cases of excess sebum or the dreaded maskne. Continue reading and discover how new studies have confirmed that willowherb extract is the natural prebiotic you need to combat acne.
The skin has a complex ecosystem of bacteria that are naturally present in the epidermis (the so-called skin microbiome), which acts as a physical and immunological protective barrier. These microorganisms are responsible for maintaining healthy skin, so any imbalance among them can trigger a host of skin problems. This is where prebiotics come in: non-metabolized substances that are responsible for regenerating the skin's natural flora.
What's new?
New studies confirm the prebiotic capacity of willowherb extract with the following results:
- Reduces inflammation (redness and irritation) by decreasing the levels of 'bad' bacteria such as Staphylococcus capitis, Corynebacterium kroppenstedtii, and Corynebacterium tuberculostearicum, which are responsible for these actions in the skin.
- Enhances skin defense, protecting against the growth and colonization of pathogenic bacteria by promoting the growth of beneficial species such as Staphylococcus epidermidis, Staphylococcus hominis, and Micrococcus yunnanensis.
Other studies have focused on one of the best antioxidants found in this plant (Oenothein B). Using a 3D facial mapping technique, they have determined how, in just 4 weeks of continuous use, willowherb is capable of normalizing excessive sebum production throughout the face, regulating the activity of the responsible enzyme, 5-alpha-reductase. Thanks to this reduction in sebum, the growth of 'good' bacteria on the skin surface is increased, while colonies of harmful microorganisms decrease. Likewise, pore size is reduced, and the skin appears matte. For these reasons, willowherb is considered an ideal natural prebiotic to combat acne.
How does it help in cases of maskne?
Online searches for remedies to control excess oil on the skin have doubled since the beginning of the pandemic due to mask use. Maskne, or acne caused by continuous use of masks, occurs when sweat, sebum, and bacteria become 'trapped' on the skin under the masks. Therefore, using a cosmetic that contains a high concentration of willowherb is key to controlling and preventing potential outbreaks, not only because it reduces sebum but also because it inhibits the growth of microorganisms responsible for pesky pimples.
