Both serums are the most effective in the industry. The difference is that Skinceuticals was the first, and has for years been many dermatologists, recommended product. It contains 15% vitamin C and has a high standard price of $166. Timeless was introduced as a copy of Skinceuticals and includes the same basic ingredients and a standard price of $25. Our recommended sellers offer both of these products at up to 50% off.

The main cause of premature aging is free radical damage. Free Radicals are produced in our bodies by the air we breathe. To see how fast it can happen, cut an apple in half and watch how fast it turns brown. Over time, free radicals play a role in developing skin damage including lines and wrinkles, and many health conditions such as cardiovascular disease, cancer and more.

Vitamin C serum is one of the most effective anti-aging ingredients you can add to your skincare routine. Topical Vitamin C is usually applied one or two times a day. It will help reverse sun damage on your face, boost collagen production, and even improve your complexion. Vitamin C is safe for most skin types.

Because your body doesn’t produce vitamin C, you need to get it from your diet, vitamins or topical creams.

Vitamin C fades pigmentation and restores brightness. It also smooths the surface of your skin, which makes it less dull and more youthful.

If you have uneven skin tone such as hyperpigmentation like sun spots or age spots, Vitamin C has been shown to positively impact skin where melanin production is too high, which makes the skin dark. Vitamin C does this by slowing the production of melanin where the serum is applied, which can fade dark spots.

One of the major benefits of Vitamin C and your body is it helps our bodies make more collagen. Collagen is a very abundant protein in our cells, but it decreases with age. It is a major building block of bones, cartilage, skin and more. Less collagen means your skin becomes less firm and supple, leading to wrinkles and fine lines. Using a vitamin C serum can help your skin cells produce more collagen and your skin look better overall.

Sagging skin is common as we age, and is another symptom of lessening collagen. Our skin loses elasticity and firmness and you may see skin sag under your eyes, on your cheeks, on your neck and elsewhere. Using Vitamin C can help tighten skin anywhere the serum is applied.

Vitamin C also helps keep pores clear of debris that leads to blackheads and acne.

L-ascorbic acid, the active form of vitamin C, has been shown both to have sun-protective ability and to fix sun damage.

If your skin does incur sun damage and you end up with a burn, vitamin C might help soothe it. Vitamin C does this by encouraging the production of healthy new cells to replace damaged and dead cells. For this same reason, it is also useful in healing skin wounds. The faster your skin heals, the less vulnerable you are to inflammation and infection, and you may scar less, too.
