Some people always have this question: If the ingredients in medicine are added to skin care products, will such skin care products be safer and more effective?

There are always people who misunderstand that the medicine used to treat skin problems is used for skin care, will it be better and safer.

Let’s analyze the ingredients that often appear in medicines and skin care products in detail below, and see what is the difference between them when they are used in medicines and skin care products.

Glycerin is a component present in the skin, and generally acts as a water-soluble moisturizer in various topical dermatological drugs. Glycerin is generally an auxiliary component, and it is relatively rare to be used as a topical skin drug alone.

Skin care products

Glycerin is one of the most excellent moisturizing ingredients because of its strong moisturizing properties.

It is a common ingredient in skin cleansers, creams and lotions. Taking into account the skin feel, the amount of glycerin added in skin care products will be relatively lower than that of topical dermatological drugs.


Vaseline became famous during World War I and World War II. It has a good healing effect on soldiers’ wounds. The main principle is that petroleum jelly can help the wound isolate air, prevent the wound from being infected by bacteria and keep the wound moist, which is conducive to wound healing.

Vaseline is mainly used as the raw material of ointment in the preparation of various dermatological external medicines. It is known as the best moisturizing ingredient with the best sealing properties, with high safety, and is not prone to irritation and allergic reactions. In addition to its excellent moisturizing function, it also helps repair the skin barrier.

Vitamin E

The main function of vitamin E in skin care products is antioxidant


Vitamin E is a very important fat-soluble antioxidant component in the human body. Vitamin E can scavenge free radicals generated in and outside the body, protect the function of cell membranes from damage, and promote the healthy operation of cells.

Vitamin E can influence inflammatory factors and regulate cell signals. Because vitamin E is fat-soluble and has a very good affinity with the skin, it can improve the state of dry skin and make the skin softer.

Skin care products

Many antioxidant skin care products will add vitamin E, which can improve the skin’s moisturizing capacity, antioxidant capacity, and prevent light damage. Vitamin E is usually used in combination with vitamin C. They can increase each other’s antioxidant capacity.

The concentration of vitamin E added in skin care products ranges from 0.1% to 1%.



Urea is also a component present in the human body. Low-concentration urea helps to maintain moisture in the skin and is a good moisturizer. Urea with a concentration higher than 10% has a slight exfoliating effect and can be used as an exfoliating product that does not damage the skin.

At a high concentration of 30%-40%, urea has a strong exfoliating effect and is suitable for more serious skin diseases such as psoriasis.

Skin care products

Urea is added to skin care products to enhance the moisturizing ability of the product, so the added concentration is relatively low.

When urea is used in skin care products, pay attention to the PH value of the product. Urea is unstable in an alkaline environment with PH>10 and an acidic environment with PH<5, and a high-temperature environment should be avoided as much as possible.



Allantoin can improve the ability of keratinocytes to bind water, which is conducive to wound healing. Dermatology topical ointments are usually used to treat frostbite, chapped and keratosis pilaris.

In medicine, zinc oxide has the effect of adsorbing grease and moisture. Zinc oxide was used in ancient Egypt to promote wound healing. Currently, it is mainly used in dermatological medicine to absorb water, inhibit bacterial growth, and promote wound healing.

Even if it enters the skin, it can be absorbed by cells, promoting the synthesis of nucleic acids and proteins, thereby promoting tissue repair. So it is a very mild, safe, and effective ingredient.

Zinc oxide can absorb oil, and it can be used as an astringent in baby diaper products.



Calamine is very mild and has anti-itch and anti-inflammatory effects in topical ointments in dermatology. It is generally combined with zinc oxide and glycerin to remove all kinds of itching caused by eczema and allergies quite quickly.

The main principle is that zinc carbonate and other trace metal ions in calamine have a mild paralytic effect on neurons in the skin.

Skin care products

Many anti-acne skin care products also use calamine to treat papules or pustular acne, and its effect is very good. However, it should be noted that this type of product sometimes contains a large amount of ethanol or isopropanol. For sensitive skin, it is best to use it on the ears first to observe whether the skin will produce an irritating reaction.

Azelaic acid also has the functions of scavenging free radicals and inhibiting cell proliferation, which is beneficial to anti-inflammatory and inhibiting telangiectasia. Therefore, it would be a great ingredient to treat rosacea as an auxiliary.
