What is a contraindication to using salicylic acid?

Salicylic acid is widely used in skincare, particularly for its exfoliating properties and ability to treat acne. However, certain conditions make its use inadvisable, such as skin sensitivity. When the skin is already sensitive, applying salicylic acid can exacerbate irritation and lead to adverse effects.

In addition to skin sensitivity, excessive sun exposure also serves as a contraindication, as it can increase the likelihood of sunburn or skin irritation when combined with salicylic acid. The use of Tretinoin or Retinol, which are both retinoids, do not inherently contraindicate the use of salicylic acid but may increase the risk of sensitivity when used concurrently.

Thus, the most prominent contraindication relates to skin sensitivity, indicating that individuals with such a condition should approach salicylic acid with caution or potentially avoid it altogether to prevent further irritation or adverse reactions.
