The German magazine "Veronidine" warned against the use of lemon juice, alcohol, mayonnaise, baking powder and cinnamon when preparing a skin care mask, because these substances are very harmful to the skin.

Lemon juice can lead to skin pH disruption. Lemon acid may cause skin irritation and inflammation, as well as make the skin sensitive to UV rays and exposed For sunburn.

Similarly, baking powder disrupts the pH and injures the upper layer of the skin, making it susceptible to bacteria, redness and inflammation.

Alcohol deprives the skin of moisture, proteins and fats and destroys the natural barrier.

Mayonnaise causes clogged pores, and then the skin falls prey to blisters and impurities.

Cinnamon irritates and burns, disrupts the pH and damages the natural protective barrier.
