Homemade Glycolic Acid Body Wash Guide
Material Preparation
1. ** Glycolic Acid **: Precisely weighed according to the required concentration and dosage. Glycolic acid has a significant effect on improving skin texture and promoting exfoliation, but it is irritating to a certain extent. Be sure to use it with caution.
2. ** Base Body Wash Substrate **: A mild, fragrance-free cleaning base is optional, which provides basic cleaning power for the body wash and has good compatibility with glycolic acid.
3. ** Moisturizer **: such as glycerin, sodium hyaluronate, etc. Adding an appropriate amount of moisturizer can hydrate and lock water for the skin while cleaning, and balance the situation of skin moisture loss caused by glycolic acid exfoliation.
4. ** Fragrance (optional) **: If you like the fragrant bath experience, you can choose a little natural plant essential oil or artificial fragrance with safety compliance to add a pleasant aroma, and then pay attention to the dosage so as not to irritate the skin.
5. ** Stirring utensils **: A clean stirring stick or mixer to ensure that the materials are evenly mixed.
6. ** Measuring cup and dropper **: Accurately measure the dosage of each ingredient.

Production steps
1. ** Determine the formula ratio **: Determine the proportion of glycolic acid, basic body wash base, moisturizer and other additives according to individual skin type and expected efficacy. For example, dry skin can reduce the proportion of glycolic acid and increase the content of moisturizer; oily skin can moderately increase the concentration of glycolic acid to enhance cleaning and oil control. Usually, the concentration of glycolic acid in the finished product should be controlled at 3% - 8%.
2. ** Measure ingredients **: The dosage cup accurately measures the basic shower gel substrate in the cleaning container, the dropper accurately measures the glycolic acid, slowly adds it, and stirres while adding to prevent the local concentration from being too high. Add the moisturizer according to the formula and continue to stir well.
3. ** Add fragrance (if using) **: Drop the selected fragrance into the mixture, and stir well to distribute the aroma evenly.
4. ** Stir well and check **: Stir continuously for several minutes to ensure that all ingredients are fully integrated. Observe the texture, color and uniformity of the mixture. If there are layers or undissolved substances, continue to stir until uniform.
5. ** Bottling and storage **: Pour the prepared glycolic acid shower gel into a clean, well-sealed bottle and place in a cool and dry place, away from direct sunlight and high temperature to ensure quality and efficacy.

Precautions for use
1. ** Skin test **: When using homemade glycolic acid body wash for the first time, apply it to a small area behind the ear or inside the arm first, and observe for 12-24 hours. If there is redness, swelling, itching, tingling and other allergic discomfort, stop using it immediately, and do not use it later.
2. ** Control frequency **: Glycolic acid has an exfoliating effect. Frequent use can cause excessive cleaning of the skin and damage to the barrier. It is recommended to start from 2-3 times a week and gradually adjust the frequency of use according to the skin's tolerance.
3. ** Pay attention to sun protection **: After using glycolic acid body wash, the skin is more sensitive to ultraviolet rays. Be sure to take sun protection measures when going out during the day after bathing, such as applying sunscreen, wearing a hat, using an umbrella, etc., to prevent sunburn, tanning and photoaging.
