You may have already heard of fruit acids but… do you know exactly what the uses of these ingredients are? You know they can be used for the well-being and care of your skin without particular problems?
In this brief study, we will try to understand why fruit acids they are so safe and effective, and why they are frequently used in products for better skin health.
What are fruit acids?
Let's start with the basics. Fruit acids are referred to as Alpha Hydroxy Acids and are known as fruit acids simply because ... derive from fruit sugars!
Furthermore, not everyone knows that on the market it is possible to find products that use the 5 main fruit acids, and that derive from natural foods, such as:
- glycolic acid, from sugar cane
- lactic acid, from milk
- malic acid, from apples
- tartaric acid, from grape wine
- citric acid, from citrus fruits
But why should we use them?
Why use fruit acids
Fruit acids have the enviable capacity of penetrate the skin where they can act effectively on living cells.
They are responsible for better cell turnover, helping to exfoliate the skin, get rid of dead cells, dissolve that film that holds dead cells on the surface of our skin to reveal newer and healthier skin beneath it.
In short, the results deriving from a regular use of fruit acids on the skin they are certainly not marginal. Suffice it to remember that the use of these substances promotes cell turnover and, therefore, helps to fade surface imperfections and fine lines and wrinkles associated with skin aging. Fruit acids can therefore contribute to the maintenance of younger-looking skin by increasing the production of collagen and elastin.
In particular, theglycolic acid it is known to be the most commonly used fruit acid in cosmetics, considering that it has the smallest molecular structure of all acids and can more easily penetrate the skin. Contrary to popular belief, glycolic acid, together with other fruit acids, can be used on all skin types, even the most delicate: it is in fact fairly anti-inflammatory and has exceptional anti-aging effects. It can remove dead skin cells without the irritation traditionally associated with traditional face scrubs.
It should also be borne in mind that the effectiveness of fruit acids has long been tested! The first ancestors were in fact already in use in ancient Egypt, and Cleopatra herself was known for her flawless complexion, probably favored by the fact that she used to immerse herself in sour milk.
Are fruit acids safe?
When we think of acid, we think of burning and irritation but ... one thing most people are not aware of is that our skin is naturally acidic and it has a protective barrier, composed of a thin oily film, composed of sweat and sebum, which is located above the outermost layer of our skin and has the main function of protecting the skin from bacteria that enter it. On the pH scale, anything higher than 7 is alkaline, and anything lower is acidic. Our skin is about 5.5
Now, alkaline products, such as soap, damage the barrier of our skin and cause it to lose its balance, causing irritation, dryness and even acne. Conversely, fruit acids help keep the skin's pH at an optimal acidity level, helping to neutralize harmful bacteria, which can lead to acne, infections or irritation.
Who shouldn't use them?
The fruit acids they are very powerful and also very safe when used correctly. Some things to remember, however, are that it is always good to avoid using them on the eye area, always wear sunscreen, as fruit acids can make the skin more sensitive to UV rays, and avoid on skin with injuries and sunburn.
It is also advisable to consult a skin care professional (a dermatologist) if you are unsure of what you are doing and what you are doing.
What sensations do you feel on the skin?
Finally, remember that it is completely normal to feel a discreet tingling when using the fruit acids, due to the acidic substance present in them. In reality, a lot depends on the acid concentration and the fact that they are very active and penetrate the skin at a level that many other ingredients cannot reach. The percentage of fruit acids varies according to the brand of skin care products. Cosmetic brands tend to have a higher percentage of fruit acids than cosmetic brands.
Depending on the strength, temporary peeling may also occur, because the skin will tend to exfoliate, releasing many skin cells. The skin adapts to fruit acids, and it is usually recommended to use them once a day and accumulate them up to twice a day to avoid any temporary flaking or dryness.
We hope these short tips have been useful in improving your knowledge of fruit acids. Of course, before trying them and in case of any doubts or questions, it is always advisable to contact a skincare specialist, who can identify with you the most suitable product for your health and beauty routine.
