You should definitely consider adding an acid toner to your skincare routine if your skin is:

• Flaky or dry
• Uneven in tone, or dull looking and lacking its usual glow
• Dehydrated and patchy, with foundation not sitting properly on the skin
• Beginning to show signs or ageing, including fine lines and open, large pores
• Oily or prone to breakouts
• Prone to hyperpigmentation, or is particularly sensitive to the sun
