Talsen Chemicals Glycolic Acid Powder (1 Oz/28 grams) DIY Glycolic Crystal Powder is Pure, DIY Glycolic Acid Lotion and Serum, Max Concentration <70%

It works to brighten skin with regular use. But caution has to be taken as it has a power of burning skin if used as a highly concentrated solution. This is a good product to brighten and soften skin when used with proper concentration. Though the package is small, it lasts long as only a little is needed for preparing a serum or mixing with cream.

Great for DIY brighteners and smooth skin cream and toner

Incredible value for making your own body lotion, toner, body wash, and peels!

Update as I was asked yesterday before it was delivered. It was delivered today and meets all my expectations. Packaged safely and left at front desk as I was gone from my apartment. Very pleased.

I received the product and used it in my serum. Everything works well. I wished the powder was more finer grained so I had to grind it a little. It was very clumpy.

Yes❤️ I mix with water and keep In a glass jar , for promixing with lightening creams

I usually make a 10% solution using distilled water, by heating the water and crystals in a small glass jar to around 175° for 30 minutes or until the crystals fully melt stirring every few minutes. After it cools, I apply it with a cotton ball and leave on for 5 minutes, then rinse the area thoroughly for several minutes with water to neutralize the acid
