Sisley Ecological Compound has to be one of the lightest Sisley skincare as this one is more like an emulsion, very fluid and runny. This is a revitalizing and hydrating product formulated with a synergistic compound of plants (Centella Asiatica, Ginseng, Rosemary, Hops and Horsetail). All these ingredients have toning and revitalizing properties. It soothes and hydrates skin, restoring tone and suppleness.

Being so fluid, you can expect the Ecological Compound to be non-sticky and non-greasy. It may not be moisturising enough on its own for especially dry skin. I use this as a pre-moisturiser and apply a creamier moisturiser over it. You could say that this is like a hydration booster.
