Best Cosmetic against Photo-Aging: The Vitamin C Serum
Vitamin C serums are anti -aging cosmetics, dedicated to those who love to take care of the skin of the face, preserving its natural beauty or fighting the small imperfections of time.
Applied to the skin using face serums, Best vitamin C Serum is beneficial because:
• fights the action of free radicals;
• attenuates or prevents the formation of wrinkles;
• counteracts the loss of skin tone;
• hides skin blemishes and other imperfections;
• Acts in the deepest layers of the skin;
• moisturizes the skin;
• stimulates cell renewal;
• helps to keep the skin young for a long time.
On the skin, vitamin C acts as a shield, placing itself as an effective protection between the skin and the external environment: the face serum is the most suitable tool for conveying the molecule into the deeper layers of the epidermis, protecting it and preserving its natural beauty, that’s why there are so many vitamin C-based products for the face and body.
Vitamin c Serum is an innovative cosmetic dedicated to face skincare, which looks like a velvety fluid to be applied to the skin in the form of drops.
The peculiarity of serums is hidden in the formulation: each serum is a concentrate of active substances, reduced into micro-molecules, designed to quickly reach the deepest layers of the epidermis.
In most cases, serums are aqueous formulas, made up of water and highly concentrated, water-soluble active ingredients.
The particular composition of the active ingredients favors an ultra-rapid absorption of the product on the skin: in fact, it will be enough to tap the serum on the face to allow the skin to absorb it immediately.
Considering that vitamin C is found in many fruits and vegetables, one might think that the skin is still able to benefit from it, simply, when we eat foods that are rich in it.
However, Research shown that vitamin C taken with food or with specific oral supplements is not sufficient to bring appreciable benefits to the skin.
Attention
The absorption of vitamin C seems to be limited by active transport mechanisms in the intestine, consequently the use of creams and serums with vitamin C seems to represent the best way to guarantee an adequate supply of vitamin C to the skin, keeping it healthy and radiant and protecting it from external aggressions.
Functions and Properties
Functions of Vitamin C on the Skin
Due to its properties, vitamin C is mainly used to formulate face serums and other anti-aging cosmetics designed to protect and rejuvenate skin damaged by the sun, free radicals and age.
In cosmetics, vitamin C serums perform important 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;
• They 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 used 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;
• ” Chrono-aging ” means the physiological aging we all undergo, regardless of smog, UV rays and other environmental factors.
Vitamin C is being touted 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 is considered the most powerful antioxidant present on the skin 3 .
Vitamin C Serums against Skin Photo-Aging
Numerous studies 4 confirm the real benefits of vitamin C applied through serums or creams to protect the skin from photo-aging, a damage which – according to what emerges from Clinical and Experimental Dermatology 5 – is mostly related to free radicals.
The so-called “ROS” are the reactive oxygen species produced on the skin in case of exposure to UVA and UVB rays.
ROS represent effective damage to the skin, as they can generate a series of dangerous effects:
• alter cell membranes;
• They damage DNA;
• alter and inhibit the synthesis of collagen.
Similar effects can cause a series of chain events, from the simplest formation of wrinkles to the most serious manifestation of skin cancer.
Vitamin C serums against Chrono-Aging of the skin
Chrono-aging is dictated by the laws of genetics.
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 support 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 face serums that contain it can also be used effectively as an anti-wrinkle remedy.
Indeed, it seems that L-ascorbic acid is an essential molecule for the biosynthesis of collagen:
• Ascorbate is a cofactor for the enzyme hydroxylase involved in the transformation of procollagen into collagen;
• Ascorbic acid is also helpful in preserving existing collagen production.
• Ascorbate can indirectly stimulate collagen synthesis by activating its transcription and stabilizing proto collagen.
