Salicylic acid is a mild form of acid that treats a number of skin conditions, including acne, warts, dandruff and calluses. Salicylic acid is a keratolytic agent, which means it helps to remove dead skin cells from the body. Because many pimples can be caused from the buildup of excess dry skin cells in the pores, salicylic acid is effective in dislodging the skin cells that may have built up, resulting in clearer skin.
Dizziness, Headache or Ringing in the Ears
These symptoms are all associated with signs of salicylic acid poisoning or an allergic reaction, along with hearing loss, vomiting, diarrhea and extreme fatigue. While this is a rare occurrence, it is possible to experience a highly adverse reaction to salicylic acid treatments. If you experience any of these symptoms, discontinue use and seek medical treatment.
Skin Irritation
While salicylic acid is considered a milder treatment than its counterparts, such as benzoyl peroxide, it still may cause some skin irritation, such as redness or warmth on the area. This may closely resemble a rash. However, this side effect is most commonly associated with occurring in children, according to acne.com. If irritation continues over time, consider discontinuing use.
Dryness
Salicyclic acid's chief benefit is that it can remove dead skin cells. However, sometimes the treatment accomplishes this goal too well and dries out healthy skin in addition to acne symptoms. If the skin is so dry it appears scaly, this may be a sign that the salicylic acid concentration is too great for application. However, if the dryness is fairly mild, apply an oil-free moisturizer to reduce any drying effects. As the skin becomes more acclimated to the treatment, dryness typically will subside.
Stinging
Because the medicine must penetrate the skin and takes on a keratolytic effect, it is not uncommon to experience mild stinging as a salicylic acid treatment is applied. This occurrence simply may be cooled by fanning the area or applying a cool compress. However, if the stinging sensation does not subside after several minutes, remove the salicylic acid treatment with cool water.
