This is a question - at 70% I'd think you'd be watering it down with distilled water. Yet, the instructions read: "Next, apply a glycolic acid 70% with a toning pad." Is this correct? Don't you dilute this to a 2 - 10% solution before using??

RESPONSE FROM BPC
Hi Laura, using directly glycolic acid 70% on the skin can be irritant, that is why we recommend diluting it down to 10-20% with distilled water.

This is incredible. Use at 10% with neroli hydrosol and liquid germall plus = makes for glass skin.

It can be added to any toner, cleanser, lotion or cream at the rate of 2-10%.

Can you add this to your facial cleanser bases or moisturizer bases?

How to use a glycolic acid toner, simply start by washing your face at night with a gentle cleanser. Next, apply a glycolic acid toner with a toning pad. Then, follow up with your favourite serum and moisturiser.
