Can i use this after the aha serum?

I would add 2 drops and mix it with your serum.

any negative affects re ph balance?

I haven't had any negative effects. I just ordered my 4th bottle. My skin does so well with this product. Everything else makes me break out. This heals my acne and helps my skin look younger.

Should this product be put on by hand or with a cotton swab?

I put it on my hand, but it’s whatever you prefer.
