TimeWise Replenishing Serum C+E

Firm, Brighten and Protect

On your search for free radical-fighting antioxidants, you likely encountered research and results touting the individual antioxidant powers of vitamin C and vitamin E. However, did you know that using a combination of antioxidants deliver superior results when compared to using a single antioxidant?

As vitamin E fights damaging free radicals, this critical antioxidant becomes depleted. In this superstar serum, it gets a vitamin C boost that reignites its age-fighting power in a dynamic cycle of replenishment. Vitamin C helps reduce uneven skin tone and discoloration, helping contribute to skin brightness and a more even complexion. Three distinct sources of vitamin C are delivered in this exclusive formula to give your skin the antioxidant-rich, age-defying power it needs. To make this serum a super skin-saver, Mary Kay scientists harnessed the multifunctional potential of navy bean extract. This innovative ingredient has been shown to help reduce the appearance of discoloration on the skin’s surface* and improve the look of more even-toned skin overall.* Use this patent-pending formula daily to see skin that’s brighter, firmer and glowing with good health.

*Based on in vivo testing

Application Tips

To use: Dispense enough serum to move the product level to the next line on the bottle window. Smooth the serum evenly over your face in an upward and outward motion.

Key Ingredients

Three distinct sources of vitamin C help brighten and firm skin:

  1. Pure vitamin C (ascorbic acid) supports your skin’s natural repair process. The antioxidant properties of vitamin C and the role it plays in supporting natural collagen production make this ingredient a vital component of skin health. In TimeWise Replenishing Serum C E®, vitamin C and vitamin E are encapsulated together so the pure version of vitamin C experiences a controlled release alongside vitamin E to help facilitate the dynamic cycle of replenishment. Vitamin E also improves the stability of vitamin C.
  2. Amla fruit extract (Phyllanthus emblica extract) is a rich source of vitamin C found in nature. It has a high antioxidant capacity to protect skin health and is shown to help support natural collagen production.** Amla is a superfruit, full of nutrients including polyphenols, minerals and vitamins.
  3. A vitamin C derivative (tetrahexyl ascorbate) has been included in the formula to perform in areas of the skin traditionally hard to reach for vitamin C. Because vitamin C is naturally water-soluble, this derivative has been modified to be oil-soluble, enhancing absorption. This modification helps ensure Mary Kay’s vitamin C technology can be more effective.

Vitamin E is one of the most powerful antioxidants known to science. By pairing it with pure vitamin C, Mary Kay scientists have extended its life, delivering antioxidant protection against premature skin aging. It begins with a special encapsulation technology that places pure vitamin C at the core, then encases this powerhouse ingredient with microspheres containing vitamin E. This pairing ensures the critical ingredients are delivered together in a controlled release to the surface of the skin.
