It is generally not recommended to add water to glycolic acid toner.
Here's why:
- Dilution: Adding water will dilute the concentration of glycolic acid, making it less effective.
- Stability: Glycolic acid is an acidic ingredient. Diluting it with water can affect its stability and potentially reduce its shelf life.
- Skin Sensitivity: Diluting the toner can make it less irritating for some people, but it might also make it less effective for others.
Instead of adding water, consider these alternatives:
- Use a cotton pad: Apply the toner directly to a cotton pad and then gently swipe it across your skin.
- Apply sparingly: Use a small amount of toner and spread it evenly across your face.
- Layer with other products: You can layer other products, such as a serum or moisturizer, over the toner to enhance its effectiveness.
Remember: Always consult a dermatologist if you have any concerns about using glycolic acid toner or any other skincare product.
