    Do you have any abrasive particles in this product? Is it a ‘physical’ scrub?

    Mixing chemical and physical scrub is a bad idea. It will cause irritation for the most skin types.

    Add it post-emulsification.  As to whether stable or not: cannot say as it depends on the other components,method of emulsification, how much glycolic acid you are adding….and…you’ll find out.

    What do you want glycolic acid to do in your formula? 1% isn’t high to cause irritation but it will not add any benefits either at this concentration. If you add it for claims, you can add even less than 1%.

    Usman, what ngarayeva is saying is that 1.0% glycolic acid will have no desquamation effect, you need to use >10.0% to get any efficacy, plus do not neutralize since it loses efficacy above pH 3. Also ngarayeva means if it is only in your formula as a label ingredient , just add less, or if you are using it as a pH adjuster, use only what you need.
