Vitamin C Serums – Anti-wrinkle Action, Efficacy, Does it really work?

Vitamin C serums have been very popular on the anti-wrinkle market for a long time now. But are they really effective? Is it true that Vitamin C degrades rapidly making the serum ineffective?  In this article we will learn more about Best Vitamin C serum in Pakistan, their Properties and their Benefits.

What is a Serum?

Serums are cosmetic products designed to complete the facial beauty treatment.

Unlike a cream, which typically has a dense and full-bodied consistency, face serums are characterized by a fluid texture: the peculiarity is hidden precisely in the formula, particularly rich in active substances, reduced into micro-molecules capable of reaching the deepest in the epidermis.

In order for serums to exercise their beneficial potential, it is important to associate them with a cream: in fact, serums were created to increase the performance of the cream, optimizing the final action.

C vitamin

Antioxidant juice

When we think of “vitamin C “, we often imagine citrus fruits: in fact, this vitamin is abundant in lemons, oranges and grapefruits.

Best Vitamin C serums were born from the idea of ​​stealing the vitamin C naturally present in fruit and concentrating it in small and precious bottles:

Vitamin C serums can be compared to real concentrated antioxidant juices for the skin of the face.

L-Ascorbic acid

L-ascorbic acid is the scientific name by which vitamin C is recognized, a well-known antioxidant, essential for our health.

Vitamin C is touted as one of the best anti-aging substances, a lifesaver for your skin, to keep it smooth, glowing, and even-toned.

Vitamin C is involved in various functions, at the metabolic, immune and skin level. Indeed, in cosmetics, it is used for the following functions:

Antioxidants/antiradicals;

Collagen synthesis stimulants;

Skin lighteners;

Skin protectors;

Vitamin C and Nutrition

The human body is unable to synthesize vitamin C; for this reason, it is important to take it through food.

However, from recent studies concerning the absorption of ascorbic acid, it has been found that the vitamin C taken through food is not sufficient to bring effective benefits to the skin, given that its absorption seems to be limited by transport mechanisms active in the intestine.

Vitamin C in Face Serums

Functional aspects

Solubility

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

Stability

Vitamin C serums usually have poor stability: in fact, when exposed to light, heat and air, L-ascorbic acid tends to lose its active properties on the skin.

Precisely because of its instability, to avoid compromising its antioxidant activity, vitamin C serums are marketed in special single-dose vials/droppers, often dark in color to protect them from light.

PH and Concentration

To preserve their functional activity, vitamin C serums must be formulated appropriately, respecting pH and concentration:

Acidic pH (3.5% or less);

Minimum concentration of 10%.

Some formulations contain vitamin C in the 20% ascorbic acid formula: such a concentration could not only cause irritation or sensitization of the skin, but could even nullify the effect of the vitamin, thus not providing any benefit.

Directions

Vitamin C serums are suitable for anyone who loves to take care of their skin.

Indeed, they are suitable for:

Delay the Chrono-aging of the skin that everyone faces;

Prevent the formation of wrinkles;

Promote collagen production;

Counteract the loss of skin tone;

Lighten skin spots;

Brighten the complexion;

Keep the skin supple;

Protect the skin from free radicals produced by the sun and pollution;

Vitamin C and its Role in Collagen Synthesis

Vitamin C (L-ascorbic acid) is essential for the biosynthesis of collagen:

Ascorbate is a cofactor for the hydroxylase of the enzymes responsible for the transformation of proto collagen into collagen;

Ascorbate can indirectly stimulate collagen synthesis by activating its transcription and stabilizing proto collagen mRNA.

Additionally, ascorbic acid is also helpful in preserving existing collagen production.

Vitamin C against UV rays

Vitamin C is often used in the formulation of cosmetics dedicated to skin aging , especially that induced by free radicals produced by sunlight.

Ascorbic acid ensures effective photo-protection in certain inflammatory conditions, including those caused by post-surgical events.

To support the topical efficacy of vitamin C, a 3-month study was performed on 19 patients between 36 and 72 years of age with moderately photo-damaged facial skin.

Topical use of 10% topical ascorbic acid for 3 months resulted in clear improvement in:

Fine wrinkles;

Roughness to the touch;

Skin laxity and tone;

Yellowing of the face;

Vitamin C and lightening activity

Vitamin C, used in the form of magnesium-L-Ascorbyl-phosphate, is often used in cosmetics to make creams, masks and face serums with lightening activity, or to lighten superficial hyperpigmentation in general.

In fact, it has been observed that magnesium-L-Ascorbyl-phosphate:

Is able to suppress the formation of melanin from Tyrosinase in melanoma cells (in vitro);

The topical (local) application on the skin is able to induce a significant lightening of discoloration and freckles in 19 of the 34 patients analyzed.

Vitamin C and healing

According to some studies, vitamin C in creams and serums is useful to help reduce the appearance of scars and speed up the healing process of wounds.
