Vitamin C, as an active ingredient in cosmetics, is extremely important in anti-aging and skin-toning processes. It will work well for both young, combination, oily and mature skin and dry, dehydrated skin. Vitamin C as a powerful antioxidant protects the skin from the harmful effects of the external environment.

Effect of vitamin C on the skin

Vitamin C in cosmetics works:

• antioxidant – fights free radicals, thus preventing premature aging of the skin,
• strengthens blood vessels – takes part in collagen synthesis, increases the elasticity of blood vessels, accelerates wound healing, ideal for vascular and sensitive skin,
• anti-aging – reduces the activity of enzymes – collagenase, elastase, hyaluronidase that contribute to the breakdown of collagen, elastin and hyaluronic acid,
• brightens hyperpigmentation – inhibits melanin synthesis in melanocytes,
• anti-inflammatory and antibacterial.

Forms of Vitamin C in cosmetics

L-ascorbic acid – INCI: Ascorbic Acid.

The acid shows high instability when exposed to external factors. It works very quickly, giving the skin a glowing effect immediately after application. Due to its rapid breakdown, it acts in the epidermis.

Ascorbyl glucoside – INCI: Ascorbyl Glucoside

It is made from vitamin C and natural starch. When applied to the skin, it works in the deeper layers of the skin, as well as in the dermis. It inhibits melanin production, reduces discoloration and rebuilds collagen.

Ascorbyl Palmitate – INCI: Ascorbyl Palmitate.

Despite its high stability, it has little biological activity-in the skin it is quickly converted to its pure form. It works on the surface of the skin and does not stimulate collagen.

Ascorbyl phosphate sodium salt – INCI: Sodium ascorbyl phospate (SAP),
Magnesium salt of ascorbyl phosphate – INCI: Magnesium Ascorbyl Phosphate (MAP)

These forms of Vitamin C have similar effects. They work only in the epidermis. SAP additionally has strong antibacterial properties, has an anti-acne effect. MAP, on the other hand, works to brighten and even out skin tone.

Ascorbyl tetraisopalmitate – INCI: Tetrahexyldecyl ascorbate

It is the most effective form of vitamin C, used in cosmetics. It comes in oil form, so it has a high affinity for the skin’s lipid layer. It is appreciated for its effective reduction of skin discoloration. It protects the skin from aging processes.

How to use cosmetics with Vitamin C?

It is important to supplement vitamin C, as our body is unable to synthesize it on its own. We must provide it in food, supplements and properly selected cosmetics. Creams containing vitamin C can be used all year round. Products with low concentrations can be used for both day and night. If we are dealing with serums or creams with a higher percentage of the ingredient, we should use them at night. When treating with vitamin C, don’t forget to use sunscreen. Cosmetics containing vitamin C should be in sunlight-proof packaging, as some forms of vitamin C can be sensitive to light.
