Pure vitamin C (ascorbic acid) is essential as an antioxidant and skin repairer. However, an aqueous solution “in serums” is poorly porous and unstable.
Here people talk about the exceptional benefits of vitamin C scientifically proven.
They show the best serums with vitamin C for the skin, which guarantees its stability and increases its penetration capacity.
What is vitamin C or ascorbic acid?
Pure vitamin C, or ascorbic acid, is an essential nutrient for humans to obtain through the diet.
Especially the skin requires high concentrations of vitamin C for its antioxidant function that protects it against environmental damage such as solar radiation.
Besides retinoids, vitamin C is one ingredient with the highest scientific endorsement as an anti-ageing treatment.
Serums with vitamin C for the skin is soluble in water and can be found in cosmetic serums in different forms, pure or modified.
The pure form is the one with the most excellent efficacy but minor stability.
Benefits of vitamin C for skin demonstrated in studies
It has been shown in clinical studies (study summary ) to be involved in the synthesis of collagen and elastin, and therefore reduces the form of signs of ageing on the skin
It is a powerful antioxidant that offers protection against oxygen free radicals generated in cells exposed to the sun, tobacco and other factors.
Serums with vitamin C for the skin brightens the skin and prevents pigmentation by inhibiting melanin production.
Other uses of vitamin C
Stimulates the production of keratocytes or epithelial cells. Stimulates fibroblast migration to heal skin wounds
Why should people apply vitamin C to their skin?
The topical application of vitamin C guarantees high levels in the epidermis (outer layer of the skin), which is most needed to combat environmental stress.
The absorption efficiency through the skin depends on the formulation of the cream or serum (see better options below).
On the other hand, vitamin C can be incorporated into the diet, reach the skin through the blood vessels that supply the dermis (deep layers of the skin), and transport to the epidermis where it is needed.
However, we must ensure adequate intake of vitamin C for this to occur.
THE BEST SERUMS WITH VITAMIN C
1. THE BEST SERUM WITH PURE VITAMIN C IN A STABLE FORMULATION (WITHOUT WATER)
Several brands offer ascorbic acid suspensions (pure vitamin C) in formulations without water, which are more stable.
In this way, oxidation that occurs in aqueous solutions prevented. Additionally, ascorbic acid is more permeable in these formulations, and they do not require an acidic pH to penetrate the skin.
The downside is that many of these creams or serums are inelegant or pasty, and vitamin C doesn’t dissolve well and can be irritating.
Advantages of waterless vitamin C formulations
They contain pure vitamin C (ascorbic acid) in adequate concentrations, from 8% to 20%. Pure vitamin C is stable in solutions without water and does not oxidize
As they have a lipid character, they favour the permeability of vitamin C without the need to reduce the pH. They are usually cheaper than formulations with water
2. THE BEST SERUMS WITH PURE VITAMIN C IN FORMULATIONS WITH WATER
Advantages of formulations with water
Ascorbic acid dissolves very well in water, and therefore these serums can contain highly effective ascorbic acid concentrations of 10% to 20%
They are exquisite formulations and pleasant to the touch due to the high solubility of the ingredients.
However, they usually contain other beneficial ingredients
3. THE BEST SERUM WITH MODIFIED VITAMIN C
FOR SENSITIVE SKIN
The modified forms of vitamin C try to ensure more excellent stability of the molecule against oxidation and overcome the significant challenge of its penetration into the skin.
Most cosmetics that claim to contain vitamin C contain modified forms or derivatives of vitamin C.
And also, we must bear in mind that vitamin C derivatives are less powerful and effective as an anti-ageing treatment.
Advantages of modified vitamin C
Modified vitamin C in an aqueous solution is more stable than pure vitamin C. Some modifications of vitamin C increase its permeability, but not all
They have an antioxidant and depigmenting effect. It does not usually irritate the skin and is best for sensitive skin
They are pleasant to the touch because they dissolved in water
How to apply vitamin C to the skin?
Vitamin C used both day and night.
It reinforces the effectiveness of sun protection against the sun’s rays, preventing the generation of free radicals during the day.
To apply the serum with vitamin C, you have to dispense about four drops on the hands and gently tap into the areas you want to put on the face ( avoid the eye area).
Do not stretch or rub the skin.
The tapping action draws the serum to the deepest layers of the skin for maximum effectiveness. Allow absorbing for 5 minutes.
If your chosen vitamin C product comes in a cream form, spread it over your face. If we are going to interpret ourselves to the sun, then apply a cream with sun protection
