Prebiotics are ingredients that feed the skin's good bacteria, also known as the skin microbiome. The skin microbiome is the ecosystem of bacteria, fungi, and other microorganisms that live on the surface of the skin and play a crucial role in skin health. Prebiotics promote the growth of good skin bacteria, which helps strengthen the skin barrier and improve skin function.

In an anti-aging facial treatment, the addition of prebiotics strengthens the skin barrier and helps maintain the balance of the skin microbiome. A healthy skin barrier is important because it maintains skin hydration and helps prevent Trans Epidermal Water Loss, which can lead to dry, dull and wrinkled skin.

Additionally, imbalance in the skin microbiome has been linked to skin conditions such as acne, eczema, and psoriasis. Using an anti-aging facial treatment containing prebiotics can help maintain the balance of the skin microbiome.

Finally, prebiotics reduce skin inflammation. Studies have shown that prebiotics calm inflammatory reactions in the skin, which helps reduce redness, irritation, and signs of premature skin aging.

In summary, the addition of prebiotics in an anti-aging facial treatment strengthens the skin barrier, maintains the balance of the skin microbiome, prevents the appearance of skin problems and reduces inflammation of the latter. This helps improve skin health and appearance, especially as part of a comprehensive anti-aging skincare regimen.
