Do you covet skin that's visibly youthful, glowing with good health? (Seriously, who doesn't?) The healthy skin you crave is within reach. Vitamin C and vitamin E are two of the strongest, most protective antioxidants available. A serum delivering a daily dose of these powerful ingredients can provide visible improvement to skin. Even if you’re not seeing visible signs of aging, supplementing your skin care routine with a serum containing vitamin C and vitamin E helps protect against invisible environmental stressors that can weaken skin health.

Vitamin C is essential.

Because the human body lacks the ability to synthesize vitamin C, it needs a daily dose of the
vitamin, either from your diet or applied topically to skin. Vitamin C helps reduce uneven skin tone and discoloration. Over time, vitamin C helps contribute to overall skin brightness and a more even complexion.

What are the benefits of vitamin C serums?
A potent antioxidant, vitamin C has the ability to brighten skin while also helping to reduce uneven skin tone and discoloration. This amazing ingredient doesn’t  stop there. Vitamin C also helps support the formation of collagen and elastin, critical building blocks of skin.

Why include vitamin E?
Vitamin C is great for skin. So is vitamin E. Put them together, and you’ve created something truly extraordinary. This “better together” pairing of two super-antioxidants is supported by decades of scientific research demonstrating how their interaction improves antioxidant performance to deliver visible results.

Vitamin E is a highly potent antioxidant critical for protecting against premature skin aging. Vitamin E is depleted as it fights damaging free radicals. When combined with vitamin C, it receives a boost that reignites its age-fighting power.

Finding the best vitamin C serum for your skin.
Not all vitamin C serums are created equal. For best results, it’s recommended you select a properly formulated serum that maximizes the potency of this essential vitamin while addressing the stability issues vitamin C is famous for. The purest, most active form of vitamin C is L-ascorbic acid. Ascorbic acid requires special handling to protect it from light and air, minimizing oxidative damage.

TimeWise Replenishing Serum C+E addresses this issue by using special encapsulation technology that places pure vitamin C  at the core, then encases this powerhouse with microspheres containing vitamin E. This  ensures the two ingredients  are  delivered together in a  controlled release to the surface of the skin.  Skin  scientists  at  Mary Kay have leveraged this dynamic cycle of replenishment to do even more for your skin.

Furthermore, because the ingredients are  highly  active, the serum comes packaged in an airtight bottle. The airless environment helps maintain maximum effectiveness from the first drop to the last. The see-through dosage window reveals how much product remains and helps ensure you apply the correct amount for every daily dose.

This power-packed serum features not one, not two, but THREE sources of vitamin C.

Pure vitamin C supports your skin’s natural repair process. By pairing vitamin E with pure vitamin C, Mary Kay scientists have extended the life of vitamin E, delivering antioxidant protection against premature skin aging.

Amla fruit 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.

A vitamin C derivative is included in this 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.

Why topical vitamin C is more important than ever.

This  powerful  formula delivers protection against  environmental  aggressors, such as  ground-level ozone (O3), that contribute to visible aging. Unhealthy ozone concentrations  are persistent  pollution problems in many parts of the globe. In addition to causing damaging respiratory effects, ozone  exposure may  also  cause  oxidative  damage to skin, according to scientific studies.†, ‡

According to the 2019 State of the Air Report published by the American Lung Association, more than four in 10 people (41.1%) in the United States live in areas with unhealthy levels of ozone pollution. In real numbers, this reflects 134 million individuals residing in counties that earned an “F” for ozone, an increase of more than 5 million individuals over the previous report published in 2014.

Ground-level ozone is an atmospheric aggressor, contributing to free-radical formation that creates oxidative stress. Oxidative stress can weaken skin’s collagen and elastin, thereby increasing fine lines and loss of firmness. Vitamin C is a proven antioxidant to combat this action, helping to neutralize free radicals in skin.
