The primary prescription-strength ingredient used in Accelerate+ is tretinoin, also known as retinoic acid or Vitamin A, which is highly effective in reducing the appearance of fine lines, wrinkles, and dark spots resulting from sun damage. Moreover, to maximize its effectiveness, your prescription is formulated with custom blends of other powerful, nourishing ingredients such as Glutathione, Vitamin C, Hyaluronic Acid, and Niacinamide. Your exact dose and blend will be determined by your dermatologist.
