The skin is a complex and dynamic organ that contributes significantly to overall human health, as it is more than just a thin membrane of the skin, which consists of three main layers: the epidermis, the dermis, and the hypodermis (or flesh). The epidermis, as an outer layer, performs a defense function against external influences. The dermis lies beneath the epidermis and includes blood vessels, collagen fibres, which give skin strength and elasticity, sweat glands, hair follicles and sweat glands. Then comes the layer of meat under the skin, which is made up of fat cells that act as insulation and help control body temperature, according to a report published by Longevity Technology.
The science behind vitamins and skin
The human body requires trace amounts of vitamins for a variety of physiological processes.
Vitamins are organic substances, and as coenzymes, they support enzymes in critical chemical processes. Vitamins, ingested through food or supplements, are absorbed into the circulation and transported to the skin cells, where they have a positive effect. Vitamins that play distinct roles in promoting skin and skin health include:
1. Vitamin A
Vitamin A, also called retinol, is a powerful antioxidant that supports healthy, youthful skin.
It helps the skin shed dead cells and reveal new, healthy skin by promoting skin cell turnover, which helps reduce the appearance of fine lines and provides a smoother complexion.
Vitamin A also has anti-inflammatory properties that help reduce inflammation and redness associated with acne.
2. Vitamin C
Ascorbic acid, another name for Vitamin C, is best known as a nutrient that is beneficial to health and is essential for producing brighter skin.
And the vital role that vitamin C plays in collagen production is one of its main functions.
Collagen protein gives the skin its structure, firmness and suppleness, to maintain skin cohesion and reduce the appearance of wrinkles and fine lines.
Vitamin C helps lighten existing dark spots by reducing the overproduction of melanin, which makes the skin look brighter.
3. Vitamin E
Antioxidant Vitamin E protects skin from deterioration caused by dangerous free radicals.
Free radicals, which are unstable molecules, can lead to oxidative stress, accelerate aging, spread wrinkles and cause other skin problems. Vitamin E helps maintain the integrity of the skin and is also beneficial for dry or dehydrated skin as it is known for its hydrating properties. Vitamin E also has anti-inflammatory properties that help soothe irritated or swollen skin. For people with sensitive or fragile skin, it can help reduce redness, itching, and irritation.
4. Vitamin D
Vitamin D helps control the growth and reproduction of skin cells to ensure their regular and continuous renewal. Vitamin D also plays a role in controlling the immune system, reducing inflammation, speeding up the healing process, and helping the skin fend off dangerous microorganisms. Vitamin D fights free radicals and protects the skin from oxidative stress from UV rays and other environmental factors.
5. B vitamins
Water-soluble B vitamins carry out multiple and diverse functions for the protection and well-being of skin and skin. The B vitamins, or vitamin B complex, are a group of vitamins essential for maintaining healthy skin, including B3, also called niacin, B5, pantothenic acid, B7, or biotin, B9, known as folic acid, and B12, which has the scientific name is cobalamin.
6. Vitamin K
Vitamin K is required for the synthesis of a few proteins involved in blood clotting and wound healing. When the skin is injured, vitamin K activates these proteins, which helps reduce bleeding and promote clot formation to close the wound. Vitamin K also supports the health of capillaries and blood vessels, which reduces blood leakage into surrounding tissues and reduces the appearance of bruising.
7. Omega-3 fatty acids
Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), in particular, play critical functions in promoting healthy skin. Because of their anti-inflammatory effects, omega-3 fatty acids can help reduce skin irritation and redness. It is extremely beneficial for people suffering from inflammatory skin disorders including acne, eczema and psoriasis. The skin’s natural barrier function is strengthened by omega-3 fatty acids, which improve the skin’s ability to retain moisture.
