Skin Care Ingredients to Use and Avoid for Normal Skin

Renee Rouleau's Vitamin C&E treatment

When it comes to getting the best results from your skin care products, it’s so important to use and avoid certain skin care ingredients.



Dimethicone. This ingredient protects, smoothes and softens without oil. (Found in Renée Rouleau Vitamin C&E Treatment)

– Algae Extract. This is a humectant derived from sea plants that improves the skin’s ability to hold onto moisture. (Found in Renée Rouleau Hawaiian Nourishing Cream)

Panthenol. This is a provitamin B5 that offers excellent hydration. (Found in Renée Rouleau Skin Drink)

– Sodium Hyaluronate (also known as Hyaluronic Acid). This is a bioactive hydrating ingredient that can bind 1000 times its weight in moisture to the skin. It has been used for years and continues to be one of the most commonly used skin-hydrating ingredients for oily skin.

– Glycolic Acid. This is an AHA that is favored because is has the smallest molecular structure and can absorb deeper within the skin. This helps to dissolve surface dry skin cells to encourage brighter, more even-toned, and smoother skin. (See our collection of alcohol-free glycolic acid serums.)..
