by Johnny Jacks

Topping the list of anti-aging skin vitamins is vitamin C. Not only is it an immune-boosting nutrient for the body, but vitamin C is also regarded as a “miracle” aid for bright, rosy skin and combating oxidative stress. So, how can we effectively and safely supplement vitamin C for the skin? Let’s explore this through the following article.

How does Vitamin C help combat skin aging?

Vitamin C is the primary component found in citrus fruits such as grapefruits, oranges, lemons, and limes. Scientifically known as ascorbic acid or L-ascorbic acid, it is an essential nutrient for overall health as well as skin health. Vitamin C is water-soluble and exists in various forms such as powder, tablets, and capsules. Not only beneficial for health, but vitamin C also has many excellent effects on the skin, such as:

Creating a protective barrier for the skin against UV rays

Unlike sunscreen, vitamin C cannot absorb light; instead, it relies on powerful antioxidant properties to protect and limit damage to the skin from direct exposure to sunlight. Transport proteins are increased in the stratum corneum cells capable of protecting the skin.

Preventing the formation of wrinkles on the skin

In addition to its role as an antioxidant, vitamin C also has the ability to synthesize proteins, stimulate, and increase the production of collagen in the skin. They help fill in wrinkles, deep furrows, and lines on the skin. In this process, vitamin C acts as a hydroxylator of collagen molecules, supporting the epidermal layer, effectively increasing skin elasticity and combating sagging.

Improving moisture for the skin

For dry and rough skin, absorbing vitamin C helps prevent water loss through the epidermal layer, thanks to the mechanism of action from ascorbic acid molecules. In cell culture models, vitamin C has shown effective moisturizing properties for the skin by synthesizing a lipid membrane layer, preventing rapid evaporation and water loss on the skin.

Enhancing skin tone, firmness, brightness, and smoothness

As one of the most powerful antioxidants, vitamin C helps prevent the formation and production of melanin pigments on the skin. Additionally, vitamin C helps fade freckles and moles, brightening the natural pink tone of the skin. Proper supplementation of vitamin C also has the ability to reduce dark circles and brighten the skin around the eyes.

Supporting the treatment of various types of acne

In studies on the efficacy of vitamin C, scientists have discovered its antibacterial and anti-inflammatory properties beneficial for supporting acne treatment, especially acne vulgaris. Not only does it have acne-fighting effects, but vitamin C also has the ability to effectively reduce scarring, blur, and fill in pockmarks and pitted scars.

Stimulating the production of new cells, healing wounds

If the body lacks vitamin C, wounds will take longer to heal than usual because vitamin C can inhibit the development of free radicals that damage cells, promoting quick wound healing. Furthermore, vitamin C is also one of the components that stimulate collagen production, playing a role in refining the structure. It impacts and restores the skin’s surface, increasing the activity of epidermal barrier formation on the skin.

For sunburns, sunburns, vitamin C has a soothing effect, reducing inflammation and swelling effectively. Therefore, in products for treating burns, ulcerative lesions caused by pressure, they all contain vitamin combined with other types of vitamins to expedite the effect.

How to safely supplement vitamin C for the body?
