How it works?

Ectoin: “The Protect” Ingredient

Ectoin, a natural biomolecule, is extracted from strains of robust bacteria which live in extremely stressful environments. It belongs to a family of ‘chaperone’ molecules whose principal function on the skin and in the body is as a natural cell protector.

Lactobacillus Ferment Lysate: The “Restore” Ingredient

Lactobacillus Ferment Lysate, is an extract which has been shown in trials to promote oxygen uptake and collagen production. It has anti-irritant properties causing a reduction in redness and inflammation on the skin.

Cottonbloom Extract: The “Maintain” Ingredient

Cottonbloom extract is a biofunctional complex composed of oligosaccharides – natural sugars occurring naturally in an array of natural sources – which help with the maintenance of skin hydration and nutrition. They are ideal prebiotics, which provide nutrients for skin bacteria. The extract claims a range of health benefits, including a stronger immune system, and overall improved skin health.

I was suffering with diagnosed Perioral dermatitis and I had used Sasta before after my beautician recommended after IPL & found it hydrated my skin so I purchased again to see .
I’m amazed it has cleared my skin back to normal!
My chin /nose area were badly affected and I now have clear skin again .
Only difference was the Sasta and no retinol.
I will 100% be using again & again & it’s now part of my morning/evening routine.

Thank you for sharing you Sásta experience with us. We are delighted to be part of your everyday routine. Team Sásta x
