How about this as a lactic acid exfoliating lotion? It contains 0.43 g lactic acid per 5ml. That equals about 8% lactic acid. Will the ph be low enough?

To improve digestion and normalize the stomach pH against flatulence and nutrient assimilation problems.
As supportive therapy for Type 2 diabetes, obesity, arthritis, etc. May be used diluted as a vaginal douche.
Promotes the maintenance and development (prebiotic) of a healthy intestinal flora.

EXTERNAL USE:
To disinfect minor wounds, foot and nail mycosis, warts, darters (scurfs) and other skin irritations.
As an adjuvant treatment for chronic skin lesions: eczema, psoriasis and other dermatitis.
As a tonic and exfoliating skin lotion.

I don't know why you couldn't, but I'm not sure how effective it would be. 8% is not a very high acid percentage even if it is all available as the free acid....which it probably isn't all free acid. Can you measure the pH? I think the free acid should be < pH 2.

Also, I am not sure if the other carbohydrate and mineral components are suitable for a "leave-on" product like a lotion. Maybe you could try using it as a mask and then wash it off?

I tend to be cautious (now) about what I put on my face so maybe it IS okay...I just don't know it is so I wouldn't. Maybe one of the DIY formulators can give a better response?

I found the online store called "the formulator" mentioned elsewhere on this forum. Guess what - they have pure lactic acid for just $5.50/16oz.
Shipping was almost ten bucks, so I ended up ordering two bottles Smile

I'd be very wary of trying food/vitamin supplements as DIY topicals. I did that years ago with some L-Ascorbic and ALA and really burnt my face quite badly. The fillers and other ingredients can be ugly on your skin.

I agree with Molly on this one, as I've burned my face with "food grade" ingredients before as well. Grape fruit extract comes to mind..... Rolling Eyes BHA times a hundred! Embarassed
