Why does Vaseline make your skin darker?

As we all know, Vaseline has many positive effects, but it also has many negative effects. It is not all positive as people see. So why does Vaseline cause skin darkening? First of all, it is certain that you are not suitable for using Vaseline. If you insist on using Vaseline, it will bring you many side effects. Next, let us understand why Vaseline causes your skin to darken?

Vaseline is a semi-liquid mixture of alkanes or saturated hydrocarbons, also called petrolatum, which is obtained by petroleum distillation. Its state is between solid and liquid at room temperature, and it comes in three colors: brown, yellow, and white, depending on its uses. The melting point is 35-50°C (some say 37-52°C). Natural vaseline is obtained from the concentrate of petroleum residual oils such as paraffin heavy oil; artificial vaseline is obtained from a mixture of mineral oil thickened with pure ceresin or paraffin and paraffin fat. Vaseline has a mineral oil smell, not a kerosene smell. It can be used as a raw material for medicines and cosmetics, and can also be used for machine lubrication. It is also the name of a company's product. There is also industrial petroleum jelly.

Vaseline is mainly composed of chemically inert hydrocarbons and has no bactericidal ability; but it is not hydrophilic and will not be absorbed. When applied to the skin, it can form a film on the surface that prevents moisture from evaporating and dissipating, keeps the skin moist, and blocks bacteria from the air from coming into contact with the skin, thereby reducing the possibility of infection. (The following are medical vaseline or other products marked for human use)

① When the weather is dry, apply it to the face, hands, feet or body skin to moisturize.

②Apply to the nasal lining to avoid bleeding due to dryness, or apply to the inner wall of the nostrils to stop further bleeding for those with nosebleeds.

③It can be used as lip balm on lips, and its oil ingredients can keep lips moisturized.

④ When you have a cold, apply it to the skin around your nose to prevent it from turning red due to excessive friction from blowing your nose.

⑤It can prevent eczema caused by long-term contact of wet diapers with the skin.

⑥ Even patients with oral ulcers can first dry the affected area with a tissue and then apply a layer of Vaseline. This can prevent the ulcer from coming into contact with the acid in the mouth and speed up the healing of the ulcer.

⑦ It is said that people who suffer from dyshidrosis may see improvement after applying Vaseline on their hands before going to bed and wearing thin cotton gloves overnight.

⑧ Vaseline is stable and not easy to deteriorate. It is also non-irritating and not easy to cause human allergies. Because of its light smell, it is suitable as a moisturizing product for people who are allergic to fragrances or alcohol additives.

Although it is normal for Vaseline to cause skin darkening, for the sake of your skin, it is best not to use Vaseline. When you no longer use Vaseline, you should find a way to buy other skin care products. No matter what skin care products you choose, you must choose the one that suits you best. This is the best method and measure.
