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 photosensitising 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.
