People with sensitive skin who are prone to dryness or redness, should avoid using the ingredient.
It should also be avoided by pregnant women and anyone who takes blood-thinning medicines as it can seep through the skin and be absorbed by the blood.
Stressing the same, Dr Agarwal told indianexpress.com that if you have extremely dry skin, you should avoid using salicylic acid as it removes oil and may aggravate dryness.
It should not be applied to large regions of the body, for lengthy periods of time, or used by children when wearing occlusive clothing.
The expert said that since it is a chemical exfoliator, you should only look for low doses or concentrations between 0.5 to 5%.
The expert added that one should target the regions of your face that have breakouts or acne scars rather than applying salicylic acid all over the face.
