Sásta Microbiome Booster Serum 30ml

A little daily support for skin that feels out of balance

When skin looks red, feels dehydrated or seems less comfortable than usual, give your routine a foundation focused on hydration and balance. Sásta Microbiome Booster Serum brings together prebiotics, postbiotics and moisture-supporting ingredients to care for the skin's natural barrier and help your complexion look calmer, smoother and more even.

Use two or three drops after cleansing, morning and evening, before your other serums and moisturiser. It is a simple addition for skin that needs support rather than another complicated step.

What it helps with

• Provides immediate hydration and helps skin retain moisture.
• Helps soften the appearance of visible redness.
• Supports a more even-looking complexion.
• Helps improve the appearance of fine lines for smoother-looking skin.
• Supports the skin's natural barrier and microbiome balance.

Who is it for?

Developed for all skin conditions, with particular relevance to visible redness, signs of sensitivity, dehydration, uneven-looking tone and pigmentation, and early signs of ageing. Individual skin tolerance and results vary.

FORMULATION APPROACH
The supplied brand information describes a science-led combination of prebiotics, postbiotics and hydrating ingredients intended to support the skin's natural balance.

Ectoin supports barrier function and hydration. Lactobacillus ferment lysate is a probiotic-derived ferment extract, rather than a claim that the serum contains live probiotic organisms. The Cottonbloom complex, trehalose and inositol complement the formula's hydration and balance-focused approach.
