Silk 101 – Lactic Acid Lotion


I have a great skin ‘secret’. Perfect for ingrown bumps, hyper-pigmentation, spot scarring, keratosis pilaris, rough skin, calluses, sebaceous filaments and more. Everything you need is  extremely affordable and it’s an easy DIY.

I suffer from hyper-pigmentation like many others. Homemade lactic acid lotion is my lifesaver product for 95% skin problems I come across. It’s easy to make, easy on my skin with an easy price.

How-to & results under the jump.

Lactic acid is a keratolytic. A keratolytic softens keratin, in turn, softening the skin, improving moisture binding capabilities and exfoliating dead skin cells.  Lactic acid is also an alpha hydroxy acid. An acid, meaning that burns and skin damage are very possible. You can  easily make skin matters worse if you’re not careful. Be very cautious and always patch test.  Do not use if you have known allergies to lactic acid.

What you will be doing is exfoliating the skin chemically instead of physically. I no longer use physical scrubs unless I’m being lazy with my skin regimen, I don’t need them.

You’ll need:
– lactic acid, preferably from here.
– any acid free lotion or cream WITHOUT carbomer. LA breaks down carbomer, a thickener, and you will end up with a watery mess.
– measuring spoons
– a small mixing bowl or anything similar
– a container for storage
– a lust for silky ass skin*
* – suggested, but optional

You want to make small quantities. You may not know the PH of what you’re using and you don’t know how you may need to tweak your formula. This way, you can rely on the preservatives in the store bought lotion to support the acid you’ve added. I typically measure in tablespoons. This keeps the amount small, and the preparation quick.

All you need to do is mix the appropriate amount of lactic to the appropriate amount of lotion. you’ ready.

What is the appropriate amount? i have no solid answer for you babe, but i have suggestions.

You have to start at a low, safe strength then ramp up as time goes on. This allows your skin to adapt to your new regimen and makes it less likely for you to burn yourself.

5-6% is a great starting point for facial and neck use.
~11-13% is a great starting point for a whole body lotion. Certain areas will need a lower/higher concentration.

You will have to do a little math.

original LA strength x amount of LA = final concentration x total yield
That’s the formula. you need to plug in 3 fixed numbers to find your winning variable. for example:

90% x 2 tablespoons = 12.8% x Y

• Y will equal 14, which is your total yield. Subtract the amount of lactic acid (2 tablespoons) to find out how much lotion you need (12 tablespoons). Make sure you use a decimal point when dealing with percentages.

To make things easier, I made a little cheat sheet for you.

1 part 90% lactic acid + 1 part  lotion = 45% concentration (2 total parts)
1 part LA + 2 parts LO = 30%
1 part LA + 3 parts LO = 22.5%
1 part LA + 4 parts LO = 18%
1 part LA + 5 parts LO = 15%
1 part LA + 6 parts LO = 12.8%
1 part LA + 7 parts LO = 11.2%

Refer to the suggestions above. It’s much easier to develop chemical burns and hyperpigmentation on areas like underarms, the neck and the areas behind your elbows & knees (folds). People differ where they have thinner skin. You need to be very gentle with these areas and use a low strength lotion.

You also have thick skin areas such as the bottom of your feet, your knees, elbows. These areas will take longer to improve and will need a higher strength solution. You must slowly ease your way into a high strength solution.

Latic acid lotion is generally universal. I do not recommend lactic acid lotion on any mucus membranes (think pink – you’ll burn your shit straight off), in-between your cheeks and the like. Your pubic mound and the area where your thighs meet your pelvis is fine. Remember, folds are more susceptible to burns.

Hair removal is where things get blurry. As i mentioned before, we’re speaking of an acid. an acid that exfoliates your skin. Applying an acid after shaving is not what you want to do. Nair/Veet is not what you want to do. Waxing an over exfoliated area is not what you want to do. Trust me.

My ‘Safe’ Recommendations
– 2 days off before shaving, 3 days off after shaving, shave with a very, very light hand. Same for epilating, or anything similar.
– 7 days off before waxing and 3 days off after waxing. Same for sugaring, or anything similar.
– No depilatory creams. Very alkaline chemicals and acids shouldn’t be mixed.

This all depends on you, your skin and the area in question. you can edit the time constrictions as you see fit.

Skin peeling will occur.  If you’re going by my directions, it should be minuscule, but may not be. The area may appear dry and/or grey. When this occurs, DO NOT PICK, PULL OR EXFOLIATE. Post inflammatory hyperpigmentation and skin damage will occur. Discontinue lactic acid lotion until the area is back to normal. Apply body safe oils and/or emollient creams. if the area appears to be red, irritated or inflamed, apply an ointment like neosporin 3-4 times a day until it subsides.

While using latic acid lotion,use proper sun protection techniques. Wear sunscreen and stay away from any clothing that causes chafing. Please don’t use with other acids unless you know what you’re well versed. There are many message boards, forums and groups that can be accessed via Google, with more information.

Enjoy, love.

    Hey lauren! i was wondering what lotion you use with LA. I’m finding it kind of tough to find a lotion without carbomer. Also, can you give me details on the application process? like are you supposed to leave it on? or wash it off?

    • lauren April 11, 2016

      hey Jessie! i had a hard time locating a lotion as well, i don’t use anything specific. i find that lower-end lotions and creams do not contain carbomer, so i usually pick random products from any dollar store. lactic acid lotion is to be applied and left alone, preferably followed by sunblock. 🙂

      • jessie April 13, 2016

        thank you! this is an amazing post! p.s. how often should i apply it?

        • lauren April 19, 2016

          no, thank you! It all depends on your skin & what you would like to accomplish. what are you using it for?

          • jessie April 22, 2016

            a bunch of stuff really: to lighten my underarms, treat my pilaris keratosis, and to lighten my bikini area because it is way way dark. also i have some nasty bug bites that are scarring!! i think it should help with that as well. my skin is sensitive and prone to discoloration :()

          • lauren May 2, 2016

            it will help with all of the above 🙂 i would start on the low end, ~12%, every other day. ramp to daily, and increase your strength on harder areas like your bikini.
