Review of Timed-Released BHA Toner and Glycolic Acid Formulation Question

Thank you for the review of Timed-Released BHA Toner. I'm glad to hear it significantly reduced facial oiliness and caused no irritation.

Regarding clogged pores, as the staff mentioned, BHA helps soften the comedones for easier extraction. The key is to observe whether new clogged pores appear. If no new ones form, it indicates the product is effective.

Concerning your question about mixing 100% Glycolic Acid to make an AHA cream, your understanding and calculation are correct. To make a 5% Glycolic Acid solution in 50ml using 100% Glycolic Acid, you would need 2.5g of Glycolic Acid and 47.5g of water.

The staff also provided helpful additional advice on formulating AHA with Glycolic Acid, recommending the addition of other ingredients, such as those that reduce irritation or provide moisture, to create a more complete formula and help minimize potential irritation from continuous use of Glycolic Acid.
