DIY Lactic Acid Mask With 2 Ingredients!




What is a lactic acid mask, and why might you want to use one?

Lactic acid is a chemical naturally found in many dairy products. It is a keratolytic product, used in medical and cosmetic procedures to eat away dead skin cells and soften keratin, resulting in softer, smoother skin.

You can spend a lot of money in a spa getting a lactic acid mask - which can be totally worth it if you have the time and money - but if you're busy and just need a quick, cheap, effective fix, this mask is for you.

Step 1: Mix and Apply Your Mask

Recommended sources of lactic acid:

  • Organic milk from cow, goat, sheep - powdered is nice because it keeps in the freezer for longer.
  • Sour milk products like yogurt or kefir.

To make this specific lactic acid mask, you'll need:

  • 3 tbs goat milk powder
  • 1-2 tbs raw apple cider vinegar
  • Optional: 1 tsp guar gum or gelatin
  1. To create the mask, mix your ingredients to form a smooth, spreadable paste approximately the texture of yogurt. The guar gum or gelatin will give the mask some slip while it's wet, making it easier to apply, and prevent the mask from crumbling and flaking off your skin as it dries.
  2. Test the mask first (on your neck below your ear is a good spot, since it's sensitive enough to react should the mask be too strong, but inconspicuous enough that any irritation will not be so visible), especially if you already know you have sensitive skin!
  3. Do not apply the mask anywhere near your eyes -- the mask actually releases acidic fumes as it dries and can be very irritating.
  4. Leave on for 10-15 minutes. Any redness should go down within about half an hour, resulting in exfoliated, glowing, rosy skin! Enjoy!

    @snanni2 :Yeah, she made this instructible just to tell a lie. Get over yourself, or get lost because that kind of attitude isn't welcomed around here.
