In a nutshell Vitamin C Brightens, Lightens and Tightens the skin. Who doesn’t want that?
High levels of Vitamin C are found in both the epidermis (outer layer of skin) and the dermis (inner layer of skin). Its antioxidant properties play a role in collagen production helping keep skin healthy which is the reason vitamin C is a key ingredient in many antiaging skin care products.
Oxidative Stress 101: Our bodies need a balance of antioxidants and free radicals. Yes, we need some free radicals (unstable molecules) which are used by our immune cells to fight infections, antioxidants keep the free radicals in check. I promise this is going somewhere… If the free radicals outnumber the antioxidants you get oxidative stress. Oxidative stress leads to diseased cells (cancer, heart problems, premature aging). Vitamin C is a powerful antioxidant that can neutralize the impact of free radicals on our cells including damaged skin cells. Topical antioxidants help our skin the same way eating an orange or papaya filled with antioxidants helps our bodies. On the skin vitamin C fights free radical damage from elements like UV exposure and air pollution which can result in skin-cancer, and pre-mature aging.
Because it is highly acidic Vitamin C used topically causes our skin to react by increasing the production of collagen and elastin. They are natural protein fibers that keep skin plump and firm countering the production of fine lines and wrinkles.
Vitamin C also naturally inhibits skin’s melanin production which is the cause of dark spots and hyperpigmentation. It not only reduces the appearance of existing dark spots, it also prevents new dark spots from forming. Leaving a more even skin tone and a youthful glow.
Skin can only absorb so much Vitamin C so it is only necessary once daily. It is up to you to decide if you want Vitamin C to be a part of your morning routine or evening. If it is applied in the morning remember your sunscreen. Vitamin C does have UV-protectant properties, but that does not take away the need for sunscreen.
Most can use topical Vitamin C for extended periods without experiencing any issues. However, you should discontinue use if you experience any irritation or discomfort.
Consuming vitamin C through our diet is also good for the skin. It enhances the effectiveness of sunscreens applied to the skin for protection from the sun’s harmful UV rays. It can also help repair and prevent dry skin. Too boost your vitamin C intake look for nutrient dense foods with high amounts of vitamin C, like Acerola Cherries, citrus fruits, strawberries, broccoli, and spinach.
