Glycolic acid can be a beneficial ingredient in skincare for some people, as it is known for its exfoliating and brightening properties. However, it is important to consider your skin type and any potential sensitivities before using glycolic acid. If you have sensitive skin or conditions such as eczema or rosacea, it may be best to avoid using glycolic acid, as it can be too harsh and potentially cause irritation. It's always a good idea to consult with a dermatologist or skincare professional to determine if glycolic acid is suitable for your skin. **

To use the ordinary glycolic acid toner, start by cleansing your face with a gentle cleanser. Then, saturate a cotton pad with the toner and gently swipe it across your face and neck, avoiding the eye area. It is recommended to use the toner in the evening, as glycolic acid can make your skin more sensitive to the sun. Follow up with your favorite moisturizer to keep your skin hydrated. It's important to start using the toner a few times a week and gradually increase the frequency as your skin gets used to it. **
