9 minutos 1009 views

Do you know what lactic acid is and what it is used for? Lactic acid is an organic chemical compound that occurs naturally in the human body and in other living organisms. It is formed from glucose during the process of lactic fermentation in muscle cells when there is a lack of oxygen available to produce energy through cellular respiration.

It is also found in some foods, such as yoghurt, cheese and other fermented dairy products, as well as in certain fruits and vegetables (especially apples, beets and cabbage).

This component can be beneficial for skin care, helping to improve the appearance of the skin by exfoliating and smoothing, but it is important to use it correctly and pay attention to any signs of irritation or dryness. We will talk about this in the next few lines.

How to use lactic acid and when to use it

Lactic acid is a mild acid commonly used in skin care products to exfoliate and soften the skin. Here are some guidelines on how to use lactic acid and when to use it:

  1. Frequency: depending on the concentration of lactic acid in the product used, it is recommended to use it one to three times a week. However, it is important to listen to your skin and adjust the frequency of use accordingly. If you experience irritation or dryness, reduce the frequency or stop using it altogether.
  2. Order of application: It is a good idea to apply lactic acid after facial cleansing and before moisturising. This allows the acid to penetrate the skin without clogging pores with other products.
  3. Moisturise: remember that it is important to follow up with a good moisturiser after using lactic acid, as it can leave the skin feeling a little dry. Apply a light, gentle moisturiser to help restore moisture to the skin.
  4. Time of day: the time of day application depends on individual skin tolerance. Some people prefer to use it in the evening to give the skin time to recover and repair while they sleep. Others prefer to use it in the morning to refresh the skin before applying make-up.
  5. Sun protection: because lactic acid can make the skin more sensitive to UV rays, it is important to protect the skin with a broad-spectrum sunscreen during the day.

In general, it is recommended to start with a low concentration of lactic acid, which can be gradually increased as the skin gets used to the product. It is also recommended to avoid using other exfoliating products while using lactic acid to avoid skin irritation. It is important to pay attention to any irritation or dryness and adjust use accordingly.

In any case, it is advisable to speak to a dermatologist before incorporating any new product into your skincare routine.

If you are already considering using this component, you should know that one of the advantages of using natural ingredients in skin care, such as lactic acid, is that they tend to be gentler and less likely to cause irritation or allergic reactions.
