Well i was wondering how to use AHA. Basically i herd after a month on the regimen you should start using AHA. i bought the Neutrogena Healthy Skin with SPF 15 since it contains AHA and it has spf. Now first question is how do i use it?
do i use it as the third step, so..
or do i add moisturizer after AHA?
my second question is how many times do i use it per day or per week? day or night or both?
and my final question is, before, i use to use Neutrogena Visibly Even Daily Moisturizer spf 30 morning and night and it worked well for me, but since im switching to Neutrogena Healthy Skin with SPf 15 can/should i still use the Visibly Even moisturizer or should i stick with the Healthy Skin for day and night since it has spf for the day
