Summary Of Common Vitamins In Skin Care Products

by | Apr 30, 2021

Most people know that taking vitamins is very beneficial to the body.

Vitamins are trace organic substances necessary to maintain normal physiological activities of humans and animals.

But, have you ever heard of adding vitamins to skin care products? The answer is that vitamins have been widely used in skin care products. And clinical trials have confirmed that these vitamins have a very good effect on the skin.

Many food extracts have been unearthed for skin care applications, such as applying cucumber slices to the face at home, potato slices to eliminate eye bags, and applying honey or egg white evenly on the face. These reflect people’s trust in the effective ingredients in food. Although some methods are beneficial, some methods are harmful.

Vitamins, as the best of these effective ingredients, have amazing performance in skin care, such as the familiar vitamin C and vitamin A. Due to the particularity of its molecular structure, it has good permeability, so it can act directly on the skin without going through the intestinal metabolism.

But in the process of use, if you want to have a good effect, you must notice the time of use and do a good job of sun protection.

Next, this post will share with you the common vitamins and their functions in current skin care products.

Oilyskinbeauty Vitamin A benefit

Vitamin A, also known as retinol, is an oil-soluble substance that is easily soluble in oil and not easily soluble in water. Adding a low concentration of retinol to skin care products has a good effect on repairing damage caused by ultraviolet rays and inhibiting acne, and can improve fine lines, wrinkles and pigmentation and other photo-aging phenomena.

For retinol to function in the skin, it needs to be converted into retinoic acid. The conversion process can be simplified as the conversion of retinol to retinene, and retinene to retinoic acid. The final effect on the skin is retinoic acid, which inhibits the production of acne and eliminates wrinkles.

Then Why Not Use Retinoic Acid Directly?

Because retinoic acid has a strong irritation, the skin will produce many adverse reactions. In order to reduce these adverse reactions caused by retinoic acid and retain its excellent skin care effects, its precursor substances are mainly used at present, including retinal, retinol and their derivatives, such as retinol palmitate, retinol Alcohol propionate, retinol acetate.

However, these ingredients have strong photosensitivity, it is recommended to use at night, please be sure to use sunscreen during the day.

Vitamin B

Vitamin B is a water-soluble substance that is easily soluble in water and not easily soluble in oil. Niacinamide, which is well-known in skin care products, is actually vitamin B3, and panthenol is vitamin B5, both of which belong to the vitamin B family.

Niacinamide is an amide compound of niacin, which is water-soluble and has a small molecular weight. In the early 20th century, studies found that niacinamide can prevent pellagra, and then niacinamide was added to cosmetics as a raw material to improve acne.

At the beginning of the 21st century, a study by Procter & Gamble showed that a certain concentration of niacinamide can inhibit the transfer of melanin to the stratum corneum, that is, niacinamide can whiten the skin. Later, it was discovered that nicotinamide can prevent protein glycation, reduce excessive sebum secretion, and strengthen the skin barrier.

Panthenol has small molecular weight, water solubility, easily penetrates the stratum corneum, and is very mild. It is an excellent skin moisturizer for relieving dry and rough skin. Ubiquinol can also improve eczema, promote the growth of skin cells, repair damaged skin barrier, anti-inflammatory and soothing.

Vitamin C

Vitamin C is also called ascorbic acid, a water-soluble substance. Vitamin C has excellent antioxidant capacity, and can also inhibit the redox reaction in the process of melanin synthesis to achieve whitening effects.

Due to the excellent antioxidant capacity of vitamin C, its structure is very unstable, and it is easily oxidized by air and loses its efficacy.

At present, common skin care products containing vitamin C are mainly added vitamin C and its derivatives, such as ascorbyl glucoside (Water-Soluble), ascorbyl palmitate (Oil-Soluble), Sodium Ascorbyl Phosphate and Magnesium Ascorbyl Phosphate (Water-Soluble).

Vitamin C has poor stability and is easy to lose its activity, but its effect is the best. Vitamin C derivatives are converted to vitamin C on the skin and then play a skin care effect. Its stability is better, but its efficacy is not as good as vitamin C.

Many people like to eat foods containing vitamin C. Although vitamin C is good for the body, if you want to whiten the skin, it is recommended to apply vitamin C directly on the skin for the best effect. Because vitamin C is easily metabolized by the intestines and stomach, it is difficult for the vitamin C absorbed by the stomach to act on the skin.

Vitamin E

Vitamin E, also known as tocopherol, is an oil-soluble substance with very strong anti-oxidation and permeability. Used in skin care products with vitamin C can improve the efficacy and stability of vitamin C.

Vitamin C and vitamin E will die after eliminating free radicals. If vitamin C or vitamin E is exhausted, it will not be able to kill free radicals. Vitamin E can resurrect the dead vitamin C and make it continue to play its role.

Vitamin E often appears in the ingredient list of skin care products as Vitamin E Acetate or Tocopherol Ethyl Acetate.

The addition amount of general products is 0.5%, mainly to prevent the active ingredients in skin care products from losing activity and improve the stability of skin care products.

Because vitamin E has excellent antioxidant properties, moisturizing creams containing low doses of vitamin E can maintain skin elasticity and delay skin aging.

High-dose vitamin E is also used to treat melasma, but it is not recommended for long-term use, and it needs to be used under the guidance of a doctor.


Vitamin applications also have powerful effects in the field of skin care.

Vitamin A can resist aging, get rid of acne, improve wrinkles and fine lines, and remove pigmentation.

Vitamin B3 is niacinamide in skin care products, and vitamin B5 is panthenol.

Vitamin C has excellent antioxidant properties and the ability to whiten skin.

Vitamin E has a very strong antioxidant capacity.
