Generally yes, COSRX AHA/BHA Clarifying Toner is considered safe for most individuals when used as directed. It's formulated with low concentrations of exfoliating acids, making it a gentle option for improving skin texture and preventing clogged pores.

  • Individuals with a known allergy to glycolic acid, betaine salicylate, or any other ingredient in the toner
  • Those who have recently undergone professional skin treatments (e.g., chemical peels, laser) without consulting their dermatologist

Common Side Effects

  • Dryness or slight peeling, particularly if overused or if skin is not adequately moisturized
  • Temporary stinging or tingling sensation upon application
  • Increased sun sensitivity, making sunburn more likely if sun protection isn't used

People Also Ask

Is COSRX AHA/BHA toner safe during pregnancy?

While the concentrations of AHA and BHA in this toner are low, it's generally recommended to consult your doctor or dermatologist before using any exfoliating acids during pregnancy or breastfeeding. They can provide personalized advice based on your specific health situation.

Can I use this with retinol or Vitamin C?

Using this toner with other strong actives like retinol, high-concentration Vitamin C, or other exfoliating acids can increase the risk of irritation, redness, and dryness. It's best to alternate usage, using them on different days or at different times of day, or to introduce them slowly and observe your skin's reaction.

Is this toner good for sensitive skin?

Many people can use this toner daily, especially if their skin tolerates it well. However, if you experience any signs of irritation like excessive dryness, redness, or peeling, reduce usage to every other day or a few times a week. Always listen to your skin.
