Hydroxy acids<\/strong> are molecules that have the ability to exfoliate and renew the skin by removing dead cells from the surface layers. Their effect depends, among other factors, on their molecular size, pH of the formula, percentage and affinity for water or oil.<\/p>\n

The best known are Alpha- and Beta-hydroxy acids and their main difference lies in their chemical structure, which determines that the former are hydrophilic, i.e. they have an affinity for water, and the latter are lipophilic, i.e., they have a greater affinity for oils or lipids.<\/p>\n

INTERESTING FACTS<\/strong><\/td>\n\u00a0Glycolic acid is the smallest acid in particle size. Therefore, it penetrates easily and performs on the deepest skin layers.<\/td>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

There are also polyhydroxy acids, but they are less well known. Their function is to moisturize and improve the barrier function. Gluconolactone and lactobionic acid are the most common ones.<\/p>\n

Hydroxy acids are plant-derived acids. For example, glycolic acid derives from sugar cane, malic acid from apples and mandelic acid from almonds. Nevertheless, they can also be synthesized through chemical or enzymatic methods.<\/p>\n

They are great ingredients to improve your complexion, but you should approach with caution. Overuse or misuse can lead to irritation or redness. A general tip would be to introduce them into your beauty routine gradually. Start by applying them three times a week and if your skin tolerates them, increase frequency. If you notice an uncomfortable sensation, decrease the number of applications.<\/p>\n

Below, we are sharing some frequently asked questions. We hope they can be of great help:<\/p>\n

Can hydroxy acids be used together with Vitamin C?<\/strong><\/p>\n

We don\u2019t recommend using them together because they will alter the ph (acidic level) of the mixture and so its power and effectiveness will diminish. But consider using them in the same routine. Use Vitamin C in the morning and AHAs in the evening<\/p>\n
