The main difference between these three products is the targeted skin type. The textures have been developed on this basis.
The Rich Cream is designed for normal to dry or even very dry skin, while the other two products are for normal to combination skin.
The Rich Cream is therefore more nourishing, more enveloping and protects against dryness.
The Gel Cream has a lighter texture.
The Intense Care has an intermediate texture, smooth and melting. It is smoother/creamier than the Gel Cream, and less rich and fresher than the Rich Cream.
And lastly, their final difference lies in their use: the Intense Care is a 3-in-1 product with day, night and night mask applications, which sets it apart from the other two.
