For a hyaluronic acid treatment that offers long lasting effects, you may want to check out creamier formulations like the La Roche Posay Hydraphase Intense Riche. This unique formula combines the benefits of a lightweight hydrating serum and a more moisturizing cream in order to deliver well balanced nourishment to the skin. For those with drier skin types, hyaluronic acid serums can actually backfire if there are no other ingredients to prevent the moisture from escaping and evaporating, especially in drier climates. In order to prevent this, products like the La Roche Posay Hydraphase Intense Riche contain occlusives, which keep the hydration, delivered through hyaluronic acid, in the skin. Because of this, this product can actually be used in two different ways, depending on your skin type. For those with dry skin, for example, this product can be used underneath a more occlusive moisturizer, while for those with oily skin, this may be enough to be the perfect dose of moisture on its own to finish off your skincare routine.
