Contraindications, Usage Precautions

Citric acid is a safe-to-use ingredient. However, it can cause some skin irritations. Avoid direct contact with the eyes and never use it undiluted on the skin.

Citric acid can have a photosensitizing effect on the skin when present in high percentages. That's why it's recommended to use a suitable sun protection during the day. As a cosmetic active, it is preferable to use it preferably in the evening. Finally, combining it with other acids (salicylic acid, glycolic acid, etc...) is not recommended.

Citric acid is a plant-based acid found in a wide variety of fruits and vegetables, particularly in citrus fruits (limes, lemons, strawberries, pineapples, oranges, etc...). It was first isolated from lemon juice in 1784 by the Swedish chemist Carl Wilhelm SCHEELE, hence its name. Today, it is primarily produced through biotechnology or by using a fungus (Aspergillus niger) through the fermentation of a sugary solution. Although it is mainly used to adjust the pH of cosmetic preparations and to prepare effervescent products, citric acid is also used as a cosmetic active ingredient. Indeed, it is valued for its keratolytic and astringent effects, promoting cellular renewal and the elimination of dead cells. It thus gives the skin a radiant glow.
