Read on to know about 7 ingredients which can harm the skin if used over a long time.

Many of us use common household ingredients to enhance our beauty as they are not only cheap but are really effective as well. However, there are a few ingredients that can harm the skin when used over time.

Egg white

Egg whites are commonly used to tighten the skin pores and make the skin appear smooth. The problem associated with this kitchen ingredient is that raw egg may be contaminated with salmonella. When this infected egg is applied close to the mouth, there is a risk of contracting stomach infection and local skin infection. These harmful bacteria also hang around the washing area or sink even after you wash away the contaminated egg white from your face, thereby making it unsafe to use.

Lemon

Lemon juice is believed to lighten the blemish, acne scars, and hyperpigmentation. However, applying this citrus fruit on the skin can even lead to a second-degree burn as the psoralens present in lemon or lime can result in a phototoxic reaction on the skin when it is exposed to the UV light.

Cinnamon

Cinnamon is consumed by many for its purifying property. Still, some people complain of being allergic to cinnamon or feeling a burning sensation after applying cinnamon oil on the skin.

Breast milk

The latest trend is to use breast milk to treat acne as it contains lauric and lactic acid, both of which offers skin healing and antimicrobial properties. Some people may unknowingly even apply breast milk pumped out from a diseased person on their face and increases their chances of contracting diseases.

Semen

It has been some time since the semen facial is popularized for its moisturizing and calming benefits. Apart from benefitting our skin, this practice may also lead to the transmission of STIs (sexually transmitted infections. It has been reported that some people may be allergic to semen, which can lead to a burning sensation or even anaphylaxis when applied over the skin.

Urine

Some people even do the unthinkable to maintain their beauty and apply their urine for its astringent and toning property. Pee facial was popular for a while as it contains urea and uric acid that can hydrate the skin, tighten skin pores, and prevent acne. However, applying urine on the skin may invite infection, particularly on existing wounds and inflamed skin.

Apple cider vinegar

This ingredient has been used for years to clear acne, fade scars, remove moles, and delay the appearance of signs of aging. Long term use of undiluted apple cider vinegar can corrode the skin because of its high acidic content. Presence of acne can also lead to burning sensation and it can even damage the cornea if it penetrates through your eyes.
