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.

Run, don't walk, to try Sasta !!

I started using Sasta about 2 months ago when my perioral dermatitis started to flare up again. I immediately ordered Sasta and it was delivered the very next day. It completely stopped the dermatitis in its tracks and my skin has never looked better. Absolutely fabulous product !! Will keep buying

Elise, I am delighted to hear Sásta helped with your perioral dermatitis and you are Sásta ( Happy )with your skin . Thank you for sharing this with us . Michelle x

Pleasantly surprised 😍

My sister bought me this serum for my birthday, I'm using it a month now morning and night time. My skin is glowing and I'm seeing a substantial reduction in a couple of dark spots I had on my cheeks. This is my new favourite serum and I will be continuing to use it.
Thank you
