Vitamin C and Citrus
Often, when we think of ” vitamin C, “we imagine citrus fruits: it is no coincidence that lemons, oranges, and grapefruits contain a wealth of vitamin C, a micronutrient popularly appreciated for its extraordinary antioxidant and anti-aging properties.
Vitamin C is known in chemistry under the term ” L-ascorbic acid. “
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.
Hence the name ” ascorbic acid ” with which vitamin C is recognized.
Vitamin C is an essential micronutrient for human health. how does PayPal work? Which is a substance that must take from the outside for the body to benefit from it.
Method of Assumption
Vitamin C can take:
- through nutrition: not only citrus fruits but also blueberries, kiwis, parsley, Brussels sprouts, broccoli, strawberries, tomatoes, grapes, and peppers are dietary sources of vitamin C;
- through specific integration ;
- by local (topical) application: vitamin C is used to formulate creams, serums, masks, or gels with antioxidant / anti-aging action.
Role in the Body
Vitamin C an essential vitamin for human health, as it involved in various metabolic functions:
- the synthesis of collagen, as it acts as a cofactor in various enzymatic reactions;
- cellular protection from free radicals;
- wound healing ;
- the regulation of gene expression ;
- the immune reactions ;

4.Benefits for the Skin
Why Use Vitamin C Serum?
Considering that vitamin C found in many fruits and vegetables, one might think that the skin can still benefit from eating rich foods.
However, from Research 1, 2, it emerged that vitamin C taken with food or specific oral supplements is still insufficient to bring appreciable benefits to the skin.
The absorption of vitamin C seems to be limit by active transport mechanisms in the intestine. Consequently, the use of creams and serums with vitamin C appears to represent the best way to guarantee the skin an adequate vitamin C supply, keeping it healthy and radiant and protecting it from external aggressions.
5.Functions and Properties
Functions of Vitamin C on the Skin
Due to its properties, vitamin C uses to formulate mainly face serums and other anti-aging cosmetics designed to protect and rejuvenate damaged skin. By the sun, free radicals, and age.
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:
- fine wrinkles ;
- roughness to the touch;

6.Vitamin C in Face Serums
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.
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.
The solution to avoid similar side effects must seek in the replacement of vitamin C in the form of ascorbic acid with other more delicate shapes, such as:
- magnesium ascorbyl phosphate ;
- sodium ascorbyl phosphate ;
- ascorbyl palmitate ;
- ascorbyl tetraisopalmitate .
7.Types of Vitamin C Face Serums
On the market, vitamin C serums are not all the same: in fact, the speed of action links to the form in which vitamin C formula, its concentration, and the possible presence of another component within the product.
Face Serums with Vitamin C as an Exclusive Component

A similar effect can generate when vitamin C formulate together with other substances (e.g., stabilizers, additives, preservatives, pH correctors, or molecules with different solubility).
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.
How does it work?
Inside each biphasic single-dose vial, vitamin C reduce to a powder and enclosed inside the cap-tank: like it, vitamin C not active. Therefore, in the bottle below, an activating solution can found.
Before use, the powder must be mixed with the solution below: in this way, the vitamins’ biological activities are preserved until the moment of application on the skin.
Generally, to ensure the skin a complete antioxidant treatment, it is recommended to alternate the application of the bottles of antioxidant vitamins (vitamins A, C, and E) cyclically: in this way, the skin can benefit from the beneficial properties of the individual antioxidant vitamins, day after day.
Face Serums with Vitamin C and other Components
In other face serums, vitamin C can associate with various functional ingredients, some aimed at enhancing the action of the same vitamin C, others aimed at carrying out additional functions.
For example, in a bottle of mixed serum, in addition to vitamin C, substances such as:
- Vitamin A (retinol): effective for strengthening the anti-acne and smoothing effect on the skin;
- 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;
