That was before terms like AHA, BHA, pH or contraindications exist.<\/p>\n\n\n\n<p>For instance, Cleopatra used to bathe in milk to gain softer and hydrated skin, thanks to lactic acid (AHA). Meanwhile, the Romans and Greeks were using fermented grape juice and lemon extracts to clear up their skin.<\/p>\n\n\n\n<p>Gypsies were reportedly the first group to use phenol for deep chemical peels.<\/p>\n\n\n\n<p>French queens were using wine yeast (tartaric acid) as skin peeling to gain brighter skin.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-introduction-for-skincare-acids-guide\">Introduction for skincare acids guide<\/h2>\n\n\n\n<p>Skincare acids have become such a popular thing nowadays. They are used for many skin concerns and yes, they can be used on most skin types. No matter if you use AHA or BHA you will only benefit if it&#8217;s the right one for your skin and if you consider the relevant precautions.<\/p>\n\n\n\n<p>Firstly, how do you know the right one for you? Which concentration or pH? How often and what do you need to take into consideration when you decide to add acids to your skin regimen?<\/p>\n\n\n\n<p>I like to call them <strong>DOMESTIC ACIDS<\/strong> &#8211; safe to buy and use at home without any guidance from physicians and skin professionals.<\/p>\n\n\n\n<p>Let me tell you a <strong>myth<\/strong> about acids: <em>The higher the percentage the more effective.<\/em><\/p>\n\n\n\n<p>Only estheticians and skin professionals will use acids that are mostly found in chemical peels or professional products with higher concentrations and lower pH. The rest is marketing and skin irritation.<\/p>\n\n\n\n<p>However, besides the marketing strategy that many companies use, you should take into consideration the fact that numerous cosmetic products appeared on the market with unfounded claims of performance.<\/p>\n\n\n\n<p>If you want to keep it simple, think that the <strong>formulation is the key<\/strong>! Trust the science and researchers. They know what they are doing. Just make sure that the brand is trustworthy.<\/p>\n\n\n\n<p>Lower concentrations are beneficial for sensitive skin and not only. There should be a balance between strength (exp. 15%) and pH (4) &#8211; the less the pH the more acidic and more aggressive it is. This means that with a 30% concentration, it may be formulated at a pH of 5-6 ( normal skin&#8217;s pH is 5.5) so you do the math.<\/p>\n\n\n\n<p>What you see on the market, is pretty safe for self-usage. What is happening in the skin and aesthetic clinics is another <a href=\"https:\/\/skineducation.eu\/chemical-peels-everything-you-need-to-know\/\" target=\"_blank\" rel=\"noreferrer noopener\">story of mine<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-left has-text-color has-link-color wp-elements-b11421a9d82a323905abcc260ff90079\" style=\"color:#5a5858\">Skincare acids guide.
