Coffee is one of the ingredients that is often used as a natural mask. The content of coffee turns out to be healthy for the skin. However, you need to be careful with the side effects of using a coffee mask.

Coffee mask side effects
Coffee is known to have the potential to treat skin beauty. This benefit can not be separated from the caffeine content.
Yes, caffeine applied to the skin helps reduce puffy face and eye circles.
Caffeine can constrict the blood vessels on the face thereby reducing blood flow to the skin.
As a result, the face and eyes are no longer swollen and dark circles under the eyes are reduced for a moment. In addition, coffee is rich in compounds that are antioxidants, such as chlorogenic acid, ferulic acid, and caffeic acid. Roasted coffee beans will also produce a brown pigment called melanoidin. This pigment is also an antioxidant. Antioxidants are important for reducing the effects of skin aging due to free radicals from pollution and ultraviolet rays. Although there is some promising potential, it turns out that the side effects of coffee masks are still possible. These are the possible side effects that can appear.

1. Allergic reaction
All skin care products have the potential to cause allergic reactions, and natural coffee masks are no exception.
This skin allergy arises due to a reaction of the immune system. When the skin touches coffee, the immune system considers the compounds in coffee to be harmful.
So, the immune system releases histamine compounds to fight the content in coffee. Unfortunately, this histamine triggers an allergic skin reaction.
Some symptoms of skin allergies due to the dangers of coffee masks that can be felt, namely:
itchy,
reddish,
dry skin, and
bumps appear.

2. Irritation
The danger of a coffee mask that you can realize as soon as you use it is skin irritation. This condition usually arises due to the coarse texture of the coffee grains.
When you apply a coffee mask, the face also experiences friction with the coffee grains. This friction turns out to be able to erode the natural layer or skin barrier of the skin.
So, the face is also prone to irritation which is characterized by a burning sensation, redness, and even wounds.
Moreover, facial skin is thinner than the rest of the body. So, irritation is easier if you use a coffee mask instead of a natural coffee scrub for the body.

3. Skin infections
The side effects of irritation caused after wearing a coffee mask can turn out to be an infection.
When the skin rubs against the coffee to the wound, bacteria and other microorganisms are prone to nesting in it so that the skin becomes infected.
As a result, you will experience:
rash,
swollen,
reddish,
painful,
pus, and
itchy.
Wounds will also be difficult to heal if they have been infected with harmful bacteria and microorganisms.

4. Black spots
Again, the danger of this coffee mask cannot be separated from the effects of wounds and infections caused. Injured and infected skin will experience inflammation.
After the wound begins to heal, the skin looks black. These dark patches are scars known as post-inflammatory hyperpigmentation (PIH). Citing the DermNet NZ site, inflammation actually triggers the formation of melanin or a natural dye produced by the skin layer. Later, melanin will be released into the injured skin. Therefore, scars arise in the form of black spots.
