It’s been a long time since we first heard an advertisement for a cosmetic line of products with a pH of 5.5. It was about products whose acidity is close to the skin, and everyone knew about that magic number 5.5 and they knew that it was pleasant to the skin. In fact, our skin is acidic thanks to the lactic acid and amino acids secreted by the sweat and sebaceous glands. Acids protect us from harmful microorganisms, such as bacteria, fungi and viruses, and any disturbance in acidity opens the door for microbes to attack.
However, acids are not only guardians of the integrity of the skin, but are a powerful weapon in the arsenal of modern aesthetic medicine that erases the signs of aging from the face and neck. The use of various natural products containing acids for cosmetic purposes dates back to ancient times. Cleopatra bathed in milk containing lactic acid, women in some parts of Asia used fermented sugar cane containing glycolic acid, and our grandmothers used to anoint their faces with lemon juice before important events.
And indeed, lactic, citric and glycolic acids are now found in numerous cosmetic products that have an excellent effect on the skin. These acids are better known as fruit acids and the sparrows on the branch already know that the skin looks fresh and rejuvenated after them. That’s why it’s not surprising that friendly girls in beauty salons will almost always offer you fruit acids as the first facial treatment.
But let’s get to know fruit acids better. Glycolic acid is certainly indispensable in this series and perhaps my favorite. Of all fruit acids, its molecules are the smallest and it penetrates the skin the deepest, where it strongly stimulates collagen production. When higher concentrations of glycolic acid are used, flaking appears after the treatment, but then the stimulating effect on the skin is stronger. Periodic application of glycolic acid in the long term increases collagen content, reduces fine lines, maintains a radiant complexion and overall makes the skin smooth, shiny and rejuvenated.
Lactic acid is particularly important because of its effect on skin hydration. Especially good effects are achieved with dehydrated skin without tone.
Salicylic acid , which normally does not belong to fruit, but is often used in a similar way, has comedolytic and keratolytic action. It is suitable for problem skin prone to acne. Thanks to its keratolytic action, it perfectly removes blackheads and spots.
All fruit acids can be applied concentrated – but the rule from American advertisements applies to them: ” Don’t try this at home “, because you can “burn” your face with unprofessional use. However, since the skin loves acids, you can daily use lotions, creams and tonics that contain low concentrations of acids, which will have a beneficial effect on the skin, and you will look younger, more beautiful and more well-groomed.
And the next time you make lemonade, feel free to put some on your face as well.
