. What's a la soak? I've stopped using my lotion as it's summer here do wanna know what this disk is cause I love me some la1f61cHey nwababy!! thanks and good hearing from you oh no don't mess the hard to find stuff chile, its so much trouble finding the right stuff for oneself as it is You know I just play it safe and stick with the light compounds, I got some ph strips, b3 and LA, oh and msm powder, thats about it. I've never had lactic acid serum, but most of my preferred ready made gels have lactic acid in them already. like CQ, IKB So the DIY LA soaking I do weekly boosts everything up. I can't apply LA on my face either, just in cq whitening cream. I have used a little LA mix with distilled water in a cotton ball and dabbed on my face but I didn't notice much of nothing. As far as the 88% LA/ dilute it with distilled water, dab on face with cotton ball patch test it first. I think it may mess up your qei+ if you mix them together. The acid will break it down, you're better off layering that. And you would have to wait 24hrs anyway so you won't irritate your face. What did you use in your attempt at making KA serum?
