So I just about the glycolic peel for 25% (starting low because it's my first time), I was wondering what is the correct procedure to apply it over my entire body?

Hi Skinstory! I don't use glycolic acid but I use lactic it is known to be gentle.Glycolic is supposed to be stronger.
I started with 35%.There is nothing special to do:
Before you just need to clean your skin with alcohol 70-90 until there's no dirt left. Then apply the peel on the area you want to treat with a cotton pad,
You need to leave the product on the skin for 4-7 min it depends on the company who makes the product some advice 5 others 7 min
I would say for the first time just stop when it start to burn and never go above 7 min.
Wash it with water (no soap)
Do not put any acid on your skin for 24 hours.(do not use acids 24 hours before)
That's pretty much all!
Good luck and tell us about your results!

Thank you for the tip mistyjane

I just purchased some Latic Acid too:)
The gentlest of the peels and ironically the first peel I messed up on.
But that was way back when I was just starting, back then I thought I had to "feel the burn" in order for a product to work. I didn't feel a thing! So I used it more than recommended and ended up with very tender and sore spot, looked like a light brown burn but it peeled after wards. Usually you don't burn with such a light peel unless your super sensitive to the ingredient.

Thank you for the tip mistyjane

You're welcome:)

Did my Latic Acid today:)
It went well and it was just as easy as the last time I remember doing it.
Afterward I applied a natural gel moisturizer.
