VITAMIN C AND SKIN AGING
An essential vitamin for the proper functioning of the body, vitamin C is also full of benefits for the skin. When applied to the skin, this active ingredient neutralizes free radicals induced by several factors such as stress, smoking, exposure to the sun, lack of sleep… Thus, it limits oxidative stress and slows down skin aging and the appearance wrinkles.
How is vitamin C good for the skin?
Vitamin C being a powerful antioxidant, it neutralizes free radicals, which cause skin oxidative stress and premature aging of the skin. Vitamin C is also essential for the production of collagen in skin cells and thus helps to support the structure of the skin and delay the signs of aging.
How is skin aging manifested?
Skin aging is an unavoidable phenomenon in living beings. It is due, among other things, to a decrease in the rate of cell renewal, a change in the composition of the dermis and the molecules that constitute it (hyaluronic acid, collagen, etc.) and the melting of fatty and muscular tissue which no longer plays a role. It’s supporting role.
In addition, this natural process can be accelerated by lifestyle (poor diet, smoking, excessive alcohol consumption, sun exposure, stress, lack of sleep…).
Skin aging then results in the appearance of wrinkles, pigment spots, visible dilated vessels and thinning or thickening of the epidermis.
Vitamin C and skin care
Vitamin C is increasingly popular in topical skin care products (external application) as it helps stimulate the skin and maintain its youthful and glowing appearance.
One of the benefits of using a vitamin C-enriched skin care product is that you can apply it precisely where it’s needed. But not all skincare products containing vitamin C are created equal, and there are a few things to pay attention to:
- Form of vitamin C: Some forms of vitamin C, such as L-ascorbic acid, are more active than others and have been tested more extensively as a skincare ingredient used in Best vitamin c serum in pakistan.
- Concentration: studies have shown that to make a difference in the skin cells the product must contain at least 8% vitamin C. Formulations higher than 20% are not more effective and can also cause irritation.
- “Freshness”: as soon as it is exposed to oxygen, pure vitamin C degrades; it is therefore more effective in a product that allows it to be combined with the rest of the formula just before first use.
Vitamin C to fight against skin aging
Vitamin C or L-ascorbic acid is particularly relevant in topical application to fight against the appearance of signs of aging. Its effectiveness is based on three essential actions:
• Neutralize free radicals:
Free radicals generated by all sorts of factors (pollution, cigarette smoke, stress, etc.) attack the cells of the skin and accelerate its aging. Vitamin C neutralizes the action of free radicals by giving them an electron in order to make these molecules more stable and less reactive. Thus, it delays skin aging and protects the skin from external aggressions.
• Stimulate collagen production:
Collagen is a fibrous protein found in the dermis that provides flexibility and firmness to the skin. However, over the years, its production by the body tends to decrease, which leads to sagging skin and the appearance of wrinkles. To overcome this, vitamin C is a real ally because it boosts the synthesis of collagen in the skin and thus slows down the appearance of signs related to skin aging.
• Prevent the appearance of spots:
Several studies have demonstrated the lightening power of vitamin C. This molecule inhibits the amount of melanin generated by the pigment cells of the skin. It interacts with Tyrosinase, an enzyme responsible for converting the amino acid tyrosine into melanin, and thus reduces pigmentation.
How can I be sure my skin is getting the vitamin C it needs?
Our body does not produce vitamin C, it must be supplied to it as a supplement. In addition, our body does not store vitamin C, so it is better to consume or apply it every day.
Vitamin C is also increasingly used in skin care products like Vitamin c serum for topical use (external application). It stimulates the skin and helps maintain a youthful, healthy and radiant appearance, and it is often among the first anti-aging products used.
