The origin of the name date back to the past, when scurvy discovers, a disease caused by a lack of vitamin C, which manifests itself in fatigue, bleeding, and bruising.

Affected sailors, realizing that scurvy recognized its origin in a vitamin C deficiency, began to feed on lemons and citrus fruits, thus managing to remedy the disease.

In cosmetics, vitamin C serums perform essential functions for the skin:

  • they are effective antioxidants. Therefore they act against photo / chrono-aging, protecting the skin from damage caused by free radicals produced by the sun and pollution;
  • have a powerful anti-wrinkle effect ;
  • they are effective lighteners, i.e., they act by making dark spots on the skin less visible.

Antioxidant Properties of Vitamin C Serums

The antioxidant properties of vitamin C are exploited to combat photo-aging and chrono-aging:

  • by ” photo-aging,” we mean the aging of the skin mainly induced by exposure to the sun’s rays;
  • by ” chrono-aging,” we mean the physiological aging we all face, regardless of smog, UV rays, and other environmental factors.

Vitamin C is advertised as one of the best anti-aging substances; for this reason, it represents an excellent remedy designed to keep the skin smooth, luminous, and uniform.

According to other sources, vitamin C consider being the most potent antioxidant on the skin 3.

Vitamin C Serums against Photo-Aging of the skin

Numerous studies 4 confirm the real benefits of vitamin C applied through serums or creams to protect the skin from photo-aging, the damage that – according to what emerges from Clinical and Experimental Dermatology 5 – is mainly related to free radicals.

The so-called ” ROS ” are the reactive oxygen species produced on the skin in case of UVA exposure and UVB rays.

ROS represent actual harm to the skin, as they can generate several dangerous effects:

  • alter cell membranes;
  • damage DNA ;
  • they change and inhibit the synthesis of collagen.

Such products can cause a series of chain events, from the simplest wrinkle to the most severe manifestation of skin cancer 5.

Vitamin C Serums against Chrono-Aging of the skin

The laws of genetics dictate Chrono-aging.

Over time, the skin of each of us undergoes inevitable alterations:

  • collagen, elastin, and hyaluronic acid are produced in smaller quantities, causing a loss of elasticity and hydration of the skin;
  • the adipose tissue (which has a supporting function) undergoes a drastic reduction, causing a progressive loss of tone and turgor of the skin.

Anti-Wrinkle Properties of Vitamin C Serums

Vitamin C has also been assigned an important role in fighting wrinkles, so the face serums that contain it can also be used effectively as an anti-wrinkle remedy.

It appears that L-ascorbic acid is an essential molecule for collagen biosynthesis :

  • the ascorbate a cofactor for the hydroxylase of the enzymes involved in the transformation of procollagen into collagen;
  • this ascorbic acid is also helpful in preserving existing collagen production 6.
  • ascorbate can indirectly stimulate collagen synthesis, activating its transcription and stabilizing the mRNA of procollagen 7.


To confirm the anti-wrinkle properties of vitamin C, we report what emerges from study 4, in which it was observed that the application of 10% topical ascorbic acid for three months on 19 subjects between 36 and 72 years with facial skin moderately photo-damaged resulted in an actual improvement on:

6.Vitamin C in Face Serums

Technical features

Despite its extraordinary potential, vitamin C must include in the serum formulas taking into account some technical characteristics, such as in particular:

  • solubility in an aqueous environment;
  • poor stability to light and heat;
  • low pH and high concentration;
  • possible adverse reactions.

Water-soluble Vitamin

Vitamin C is a water-soluble molecule, i.e., soluble in an aqueous environment: most serums contain vitamin C in an aqueous solution, which is clear and straw-colored.

Little Stable Vitamin

Vitamin C contained in serums is generally not very stable. Is AirPods waterproof? Exposed to light, heat, and oxygen, L-ascorbic acid tends to lose its skin functionality.

The loss of effectiveness of ascorbic acid can perceive through the simple observation of the formula, which, from straw-colored, tends to turn to brown: a similar effect can reduce the antioxidant capacity of the serum.

PH and Concentration

To allow vitamin C to express its functionality, it is crucial to respect pH and concentration.

Generally, in sera, ascorbic acid should meet the following parameters:

  • acid pH (equal to or less than 3.5%);
  • Minimum concentration of 8-10%.

Adverse Reactions Related to the Use of Vitamin C Serums

Usually, ascorbic acid is formulated at a concentration ranging from 8 to 20%, at a low pH (<3.5): on the one hand, these characteristics ensure a potent effect on the final product, but on the other hand, they can cause series of side effects such as localized irritation, redness, and skin sensitization, especially for those suffering from susceptible skin.


A concentration of ascorbic acid of 20% could not only cause irritation or sensitization of the skin. Still, it could even frustrate the vitamin’s functionality, providing no benefit 9 to the skin.

  • ascorbyl tetraisopalmitate .

Therefore, to preserve the integrity of vitamin C, serums containing vitamin C – or other antioxidant vitamins – are available on the market as the only constituent: for example, vitamin C may represent the only active ingredient in special biphasic single-dose vials.

  • Vitamin E: effective for enhancing the antioxidant action of vitamin C;
  • hyaluronic acid: used for its moisturizing and elasticizing activities, helpful in ensuring the skin elasticity and hydration, as well as preventing the appearance of small wrinkles;
  • collagen: it is an essential connective tissue protein that, added to the formula, gives strength and structure to the skin, favoring skin tone and fighting wrinkles;
  • alpha-hydroxy acids: they strengthen the lightening action of vitamin C, exfoliating the skin and smoothing the scars left by acne;
  • SPF: are the sun protection factors;
