Microbiome & Skin Barrier: Why Are They Essential?
The skin is protected by a skin barrier made up of three fundamental elements:
- The hydrolipidic film: a mixture of sebum and water that maintains hydration and prevents pathogenic bacteria from entering.
- The cells of the stratum corneum: a veritable wall of keratinocytes that prevents water from evaporating.
- The skin microbiome: a subtle balance of good bacteria that protects the skin from inflammation and external aggressors.
When this barrier is unbalanced, the skin becomes reactive, more prone to redness, imperfections and dehydration.
How to Care for Your Skin Microbiome
1. A gentle routine: don't over-exfoliate!
Exfoliation is essential for renewing cells and improving the radiance of the complexion, but over-exfoliating with acids that are too strong or used too often weakens the skin barrier and disrupts the microbiome.
Adopt balanced exfoliation:
- Sensitive skin: once a week with an enzymatic exfoliant.
- Normal to combination skin: once or twice a week with a gentle AHA (lactic acid, PHA).
- Oily skin: no more than 2 to 3 times a week with a gentle salicylic acid.
Tip: Alternate with hydrating, soothing skincare to strengthen the skin barrier after exfoliation.
2. Hydrate and nourish to restore the skin barrier
Balanced skin is well-hydrated, protected skin.
The essentials of a restorative routine:
- Serums based on ceramides, niacinamide and hyaluronic acid to restore the skin barrier.
- Creams rich in prebiotics and probiotics to strengthen the microbiome.
- Light plant oils (squalane, camellia oil) to nourish without clogging pores. Phytosqualane, derived from plant squalane and found in the Hydrating H.A. Complex Serum, is a biomimetic active ingredient naturally present in human sebum. Unlike heavy oils, it intensely nourishes the skin without clogging pores, thereby helping to restore the skin barrier and maintain optimal hydration.
3. Sun protection: an essential shield
UV rays are one of the main aggressors of the skin microbiome. Repeated unprotected sun exposure damages the lipid barrier and weakens the skin.
Opt for a daily SPF 50+, even in winter, to preserve your skin's balance.
Microneedling: an expert treatment to regenerate the skin without aggressing it
Among the treatments that repair and stimulate the skin without aggressing it, microneedling is an ideal solution.
This technique involves creating micro-perforations in the skin to stimulate the production of collagen and elastin, while activating the skin's repair mechanisms. Unlike aggressive peels, microneedling respects the skin microbiome and does not destroy the protective barrier.
The benefits of microneedling for the microbiome and skin barrier:
- Improves the texture and elasticity of the skin without disturbing its balance.
- Strengthens the skin's ability to retain hydration.
- Reduces redness and imperfections while stimulating cell renewal.
Combined with serums rich in restorative active ingredients, this treatment optimises skin regeneration without aggressing the skin.
Conclusion: Balanced Skin Is Healthy Skin
Caring for your skin microbiome means preserving the health and beauty of your skin in the long term. By avoiding over-exfoliation, adopting a protective and restorative routine, and choosing expert treatments such as microneedling, you strengthen your skin barrier for radiant, soothed and healthy skin.
