This is something I wanted to try for ages, all the trusted beauty bloggers and Youtube beauty gurus always refer to this product as holy water, literally! SK-II Facial Treatment Essence contains over 90% of pure Pitera that helps to restore skin's vitality. Pitera is a magical ingredient that is found in all SK-II skincare products, but it is especially concentrated in this essence! Pitera is a blend of vitamins, amino acids, minerals and organic acids, which helps to promote the natural 28 day skin cell renewal process. Hence why not a drop of this holy essence should be wasted, I shake about half a teaspoon of this precious liquid into my palm as recommended and then massage it straight into cleansed skin, the goodness of this essence is absorbed instantly. I find it makes my skin look a lot clearer and smoother. The essence should be used daily to keep skin moisturised and radiant.
