8 Toxic Ingredients You Should Never Use in Your Skin Care Routine

The chemical ingredient: Retinol

Explanation: "Retinol (or vitamin A) helps to smooth skin and reduce the appearance of acne scarring and wrinkles."

The natural option: Rosehip oil and sea buckthorn

Why it works: "Oils rich in vitamin A provide the same skin-smoothing effects as retinol, but don't cause the drying, irritation, and sun sensitivity that can come with synthetic forms."
