Why Is Vitamin C Important For Your Skin?


In both nutrition and skin science, vitamin C is a multitasking wonder when it comes to supporting your health inside and out. As a high-quality ingredient in serums, cleansers and other products, it has the power to make your skin appear healthier, fresher and more youthful.

If vitamin C isn’t already part of your daily skincare routine, here are plenty of reasons to try it.


Benefits of Vitamin C

Vitamin C in skin care helps prevent and reverse skin aging through its antioxidant and anti-inflammatory properties. It is also important in creating and repairing damaged areas of skin. Vitamin C helps build collagen and elastin — essential for resilient skin — and aids in DNA repair.


In addition, it is instrumental in repairing the skin’s lipid barrier, which accelerates wound healing. There is also some evidence that this nutrient may reduce the risk of developing skin cancer. Let’s take a closer look at each of these features.

a) Glowing skin

Adding vitamin C as an active ingredient to your skincare routine will give you a healthy glow. This is because vitamin C easily exfoliates and improves the overall appearance of your skin tone.


b) Increased collagen and elastin production

As we know, collagen and elastin are the keys to youthful looking skin. Both are structural skin fibers that our skin needs to maintain its plump, fresh appearance and elasticity. Our bodies produce both naturally, but as we age, production slows down. The result is fine lines and wrinkles. Vitamin C stimulates your body to produce more of both fibers, which helps your skin look younger and become more resilient.

c) Naturally anti-inflammatory

Additionally, in skincare, vitamin C imparts natural anti-inflammatory properties to any product that uses it. This is good news for anyone suffering from rosacea, acne, or any other skin condition closely linked to inflammation. With regular use, these skin care products reduce unsightly redness and support skin healing.


d) A natural antioxidant

Every day our skin is exposed to harmful free radicals from various types of environmental stress. Dust, ultraviolet rays, visible blue light, smoke and other particles can wreak havoc on the health and appearance of your skin. As a natural antioxidant, vitamin C helps keep free radicals under control and supports the body’s efforts to repair DNA damaged by these attackers.

e) Evens out skin tone

Who doesn’t love an even, healthy, glowing skin tone? However, most of us see brown spots on our skin as we age or the effects of sun damage. Vitamin C to the rescue!

Interestingly, skin care products that contain this nutrient as an active ingredient have the ability to reduce the transfer of brown pigment, known as melanin, from pigment-producing cells called melanocytes to the surrounding skin cells called keratinocytes. As less pigment reaches the surrounding cells, brown spots lighten and may even disappear over time.

f) Promotes wound healing

Let’s face it – none of us go through life without cuts and bruises and a few scars. However, unsightly scars can damage your self-confidence. Vitamin C helps wounds heal faster and reduces the formation of raised scars. As an active ingredient in skin care products, vitamin C increases the rate at which fibroblasts multiply. This is a cell type that secretes collagen, one of the most important fibers needed for tissue remodeling and cell survival. Numerous clinical studies have shown how effectively vitamin C supports wound healing.

A closer look at the science

Compared to other vitamins in skin care, vitamin C is relatively well researched. This means that skin scientists have gathered a lot of knowledge to determine that this wonder drug really is one of the best vitamins for your skin. Many skin care products contain ingredients that are said to reverse the signs of aging. In the case of vitamin C, scientific studies have clearly shown that this ingredient can improve these signs. Several studies went beyond accounting for improved physical appearance, which is notoriously difficult to measure. Instead, they chose objective measures of collagen deposition in the skin and calculated wrinkle depth. Both improved when vitamin C was added to a person’s skin care routine.

In addition, fibroblasts (cells responsible for producing collagen) rely on vitamin C to do their job. Scientists have collected numerous in-vitro, i.e. laboratory-generated, data to make this dependence clear. If fibroblasts don’t have enough vitamin C, they can’t produce enough collagen. As a result, the collagen-elastin balance in your skin suffers and the signs of aging become more visible.

The outer layer of your skin, the epidermis, is made up mostly of cells called keratinocytes. In addition to their role in aiding wound healing, they also act as protection against sun damage. Skin keratinocytes can accumulate and store high concentrations of vitamin C. Along with vitamin E, this ability helps protect skin from the worst effects of UV radiation. Scientists have demonstrated this ability through laboratory studies using cultured cells, and their findings have been supported by information from animal and human studies.

Consider your diet

While we focus on vitamin C as a skincare ingredient, it’s worth taking a moment to think about nutrition. What you eat inevitably has a noticeable impact on the appearance of your skin. Several studies have shown a link between good skin health and participants’ fruit and vegetable consumption. While there isn’t enough data to prove beyond a doubt that vitamin C is responsible for this effect, one thing is clear: Eating fruits and vegetables increases your vitamin C intake. Make sure you’re getting enough vitamins from your diet to improve your skin’s appearance.

Different forms of vitamin C and which one to choose

But back to the vitamin C in skin care products. Not all products containing vitamin C are created equal and not all are suitable for every skin type. Today’s skin care products contain different forms of vitamin C, and each has its strengths and weaknesses. We’ve listed some of our favorites below, but don’t hesitate to contact us for more advice.

Considerations when choosing vitamin C-based skincare

First, consider the type of vitamin C used in the product. At the risk of turning this article into a little chemistry lesson, here are a few different forms you might come across: L-Ascorbic Acid, THDA – Tetrahexyldecyl Ascorbate, MAP – Magnesium Ascorbyl Phosphate or Calcium Ascorbate are just some of the options.

The pH of the product also plays a role. According to recent studies, a pH below 4 is best for water-based vitamin C products. Another factor is the concentration of vitamin C in the product you are using. If your skin is sensitive and tends to react to new additions to your skincare routine, it may be a good idea to start with a lower concentration. You can always increase it once your skin has become accustomed to vitamin C.

Skin care is a very personal choice, and there is rarely one product that offers the perfect solution for everyone. Before we share some of our favorite products with vitamin C in scientific skincare solutions, let’s take a look at when it’s best to use them.

In our experience, vitamin C works best when applied during the day, perhaps as part of your morning skincare routine. Remember some of the benefits we talked about at the beginning of this article? These included UV protection and reduced inflammation.

During the day you are exposed to the sun’s ultraviolet rays, so your skin needs the most protection during this time with antioxidants such as vitamin C in combination with a good quality sunscreen. Inflammatory skin diseases such as acne or rosacea are closely linked to environmental irritants and pollutants. Again, you are much more exposed to these during the day than at night. When you make skincare vitamin C a part of your morning routine, you get the best protection.

After about three weeks of consistent use of a high-quality vitamin C serum, your skin builds up an “antioxidant reservoir”.

Favorite vitamin C cleanser and toner

Cleansing and toning are part of most people’s skin care routine. You can make them work harder for you by using vitamin C based skin care products.

Combination of vitamin C with other skin care products

Vitamin C in skin care products combines well with several other active ingredients.

ferulic acid, for example, helps stabilize vitamin C in the form of L-ascorbic acid, making it less susceptible to direct sunlight and heat. It basically extends the life and effectiveness of your vitamin C serum.

This vitamin also works well with vitamin E. Both ingredients help protect skin from UV damage, but they prevent different types of UV damage, making them more effective in combination than individually. Combining all three of the above pretty much triples the protective power.

In addition, vitamin C serums are also a great base for sunscreen. Although they cannot replace sunscreen, they increase its effectiveness.

Be careful when mixing vitamin C with products that contain retinol, glycolic acid, and salicylic acid. Although all are powerful skincare products, applying them one on top of the other can cause redness and irritation. If you want to use both or more, consider using one in the morning and one in the evening after a thorough cleansing routine.

After all, it’s hard to go wrong when adding vitamin C to your skincare routine. A multitasking ingredient, it can help even out your skin tone and minimize redness caused by inflammatory skin conditions like rosacea. As a natural antioxidant, it also protects your skin from UV damage and free radicals. In addition, vitamin C has been shown to accelerate wound healing and minimize scarring.
