How Does It Work?

Vitamin C serum basically works by naturally boosting your skin’s ability to produce collagen, which gradually declines through the normal aging process.

Constituting about three-quarters of your skin, collagen and elastin fortify skin strength and flexibility.

As collagen subsides, wrinkles and sagging inevitably appear, blemishing your face and body. Studies have shown that it is the best ingredient for slowing the natural breakdown of your body’s existing collagen by influencing the enzymes responsible for its degradation.

The top rated vitamin C serum combat the damage caused by free radicals to your face and body. Free radicals are uncharged molecules with unpaired electrons, which cause damage to your skin’s cells when they steal electrons from strands of collagen protein.

These molecules are often a result of the environment, like UV rays, pollution, or cigarette smoke, and they have detrimental effects on skin, causing discoloration, loosening, and wrinkling. Although our bodies are programmed to fight free radicals, that slows with age, leading to aging of the skin.​​​

​By using the best vitamin C face serums, you can boost your skin’s natural defensive mechanism by replenishing it with antioxidants and providing it with added nutrients for additional age reversal.

​When it comes to combating free radicals, this product has proven to be the best and most effective antioxidant source and electron donor to prevent and repair damages done by these molecules. There truly are no other solutions that can outperform it and if you want to know what the advantages are then read the article about the benefits of vitamin C serum.

Organic Vitamin C serums are produced using 100% certified natural and organically grown ingredients.

Both organic and non organic serums are useful and can help your skin. But what is the difference between the two? Well, the main difference is ingredients. Organic vitamin C serums contain of natural ingredients mostly.

They are regarded as better and more effective. But as you can suspect, organic products are more expensive.

What are the Key Ingredients?

The key ingredients in Vitamin C serums are hyaluronic acid and ascorbic acid which combine moisturizing and rejuvenating benefits.

As a leading source for the best vitamin C serum reviews on the web, we believe you should know about all the ingredients to look for when scouting out the products, not just the headline ones.  (1) So, before you dive into our evaluations, here is a glossary of the most common ingredients you should familiarize yourself with:

Hyaluronic Acid (Key Ingredient)

Hyaluronic Acid helps to hydrate and moisturize the skin for rejuvenation and replenishment. Known for its absorption qualities, it also regulates hydration and prevents too much moisture. Great for oily or sensitive skin that needs a balance of moisture.

Other Important Ingredients:

key ingredients of the serum
  • L-Ascorbic Acid: often referred to as ascorbic acid, L-ascorbic acid is the most researched source of vitamin C to replenish the skin. This powerhouse solicits the synthesis of collagen and combats the aging effects of free radicals and environmental stressors. It is water soluble and often paired with other pure ingredients to improve penetration of skin.
  • Sodium Hyaluronate: A salt derived from hyaluronic acid, it provides many of the same hydrating benefits, while also penetrating deeper into the skin layers. These two ingredients can be used interchangeably, or even together.
  • Propylene Glycol: a penetration enhancer intended to help the serum deeply saturate the skin, producing the best effectiveness compared to just using a water-based formula.
  • Ferulic acid: a plant-based antioxidant occurring naturally in the seeds of certain fruits, such as apples and oranges. It is an excellent defense against the damages caused by free radicals.
  • Aloe (Aloe Barbadensis Leaf Juice) Vera Gel: Aloe gel or extract helps soothe inflamed skin and prevents irritation. Protecting skin from UV photodamage and from bacteria, aloe is another key ingredient in the top-rated pure vitamin C face serums.
  • Vitamin E: a lipid-soluble antioxidant that helps combat the effects of free radicals, which often target the lipid cell membrane.
  • Green Tea: a rich source of antioxidants that, when combined with a vitamin C face serum, provides outstanding benefits. Green tea guards skin from the damages of UV rays.
  • Rose Hips: berry-like fruits that come from roses; this rich source is 20 times more potent than an orange.
  • Vitamin C Ester: a derivative of Vitamin C, but more stable than the original nutrient and with less potential for breakdown due to environmental exposure. Ester serums have many of the same properties while providing enhanced effects.

How to Use It on Your Face and Skin:

All the serums that we feature on our site and review are easy to use. No invasive facelift procedures, no awkward and uncomfortable facemasks, no weird instructions.

The simple and straightforward application is another reason why vitamin C face serums rank high in reviews of user satisfaction. Serums typically come in a dropper style bottle, with instructions to apply a few drops every night or every other night onto clean skin.

The anti-aging potential has been long studied. A recent six-month-long clinical trial studied the effects of vitamin C face serums in reversing the damages to skin caused by overexposure to the sun.

The patients who received the topical cream showed significant reductions in wrinkles and overall improvements to the appearance and texture of their skin compared to the control group.

In another similar three-month clinical trial, researchers used photographic assessments to reveal that subjects who received daily topical treatments experienced a 57.9% improvement in their skin’s appearance and elasticity.
