- The formula can be mixed. - Can be used during the day. Because it is similar to slap water. - Can be applied every day. - Suitable for general skin care. But if the owner of the post has very dry skin Should apply a skin cream containing wax or oil as another step. ** Additional advice - if allergic สารกันเสีย Phenoxyethanol should be changed. สารกันเสีย other types - if used, it feels sticky and stiff, should Put Water Soft in the formula to reduce toughness and adjust the filter Smooth to apply, thank you.

Hello, please check the pH of the formula because Lactobionic Acid will make the pH relatively low if วัดค่า pH and found that it is lower than 3. It is recommended to adjust the pH by adding a weak alkali to adjust the pH higher than 3 or may reduce the rate of use. Lactobionic Acid down so that the pH is less than 3 because if the pH is lower than 3 there is a chance to irritate the skin though Lactobionic Acid is gentler. AHA Very anyway
