What are the main effects of Glycolic Acid?
Glycolic acid, also known as glycolic acid, is an organic compound with a wide range of uses in many fields. Its main effects are as follows:
In the field of medical beauty, the effect is significant. First, it has excellent exfoliation effect. It can loosen the connection between keratinocytes, promote the shedding of the old and waste stratum corneum, accelerate the metabolism of the skin, and make the skin smoother and more delicate, like a new life. This effect can effectively improve the rough and dull state of the skin, making the skin glow. Second, it can stimulate collagen synthesis. It can penetrate deep into the bottom layer of the skin, activate related cells, increase collagen production, enhance skin elasticity, reduce the production of wrinkles and fine lines, delay the aging process of the skin, and help the skin maintain a firm and youthful state. Third, it is also helpful for improving pigmentation. Glycolic acid can inhibit tyrosinase activity, reduce melanin production, and accelerate melanin metabolism, thereby fading pigmentation, brightening skin tone, and making skin tone more uniform.
In chemical production, it also plays an important role. Glycolic acid can be used as an excellent chelating agent to form a stable complex with metal ions. In electroplating, printing and dyeing industries, it can effectively remove impurities on metal surfaces and improve product quality. At the same time, adding glycolic acid to detergent formulations can enhance the softening ability of detergents to hard water, improve washing effect, and make clothes cleaner.
In agriculture, glycolic acid also plays a positive role. It can be used as a plant growth regulator. Appropriate use can promote the growth of plant roots, enhance the root system's ability to absorb nutrients and water, and improve plant stress resistance, such as drought resistance, cold resistance, etc., so as to help crops thrive and achieve the effect of increasing production and income.
In summary, glycolic acid, with its diverse effects, occupies an important position in many fields such as medical beauty, chemical production, and agriculture, bringing many benefits to people's lives and production.
Which skin types are Glycolic Acid suitable for?
Glycolic acid is a common ingredient in the field of beauty and skin care. It can be adapted to many ointments when it is suitable for skin type and used properly.
In ancient times, although there was no name of glycolic acid, the ancients also explored many similar effects when they were taking care of skin and beauty. When it comes to suitable ointments, such as Angelica ointment, Angelica is warm and tasty, which has the functions of removing wind and pain, reducing swelling and removing pus, and drying and stopping the belt. Glycolic acid can promote the metabolism of the stratum corneum, and Angelica can also improve the appearance of the skin. The two are compatible, or can increase the effect of skin care. Glycolic acid can help the active ingredients of Angelica more easily penetrate the skin and achieve the purpose of nourishing and repairing.
Another example is Yurong Powder, which contains Baihe, Aurora, White Stiff Silkworm, etc. Baihe converges and stops bleeding, reduces swelling and builds muscle, clears heat and detoxifies, disperses knots and relieves pain, and White Stiff Silkworm dispels wind and tremors, and reduces phlegm and knots. The use of glycolic acid with it can optimize the skin's absorption of various medicines in Yurong Powder, improve skin color and texture, and make skin more delicate and shiny.
Another example is almond cream, almonds are rich in oil and a variety of nutrients, which can moisturize the skin. Glycolic acid cooperates with almond cream. At the same time as exfoliating, it borrows the moisturizing of almonds to make the skin old and renewed, without losing moisture and nutrients, and achieves the best effect of moisturizing the skin.
When using glycolic acid with various ointments, it must be done with caution. Because glycolic acid has a certain irritation, it is necessary to adjust the dosage and frequency according to personal skin conditions to prevent skin discomfort. In this way, glycolic acid and various ointments can complement each other and achieve the purpose of ideal skin care.
What are the precautions for using Glycolic Acid?
Glycolic Acid is glycolic acid, which is a widely used ingredient in many fields such as beauty, skin care and chemical industry. When using glycolic acid, the following points should be paid attention to:
The first concentration is controlled. Glycolic acid has a certain exfoliation effect, and the concentration has a different impact on the skin. If the concentration is too low, or it is difficult to achieve the expected effect; if the concentration is too high, the skin's tolerance will be worrying, and it is easy to cause redness, swelling, tingling, peeling and other discomfort. In ordinary skin care products, the concentration of glycolic acid is mostly 2% - 10%. For first-time users, it is recommended to choose products with a lower concentration of 2% - 5%. After the skin adapts, the concentration should be increased as appropriate.
The second time is the skin Before launching a new product containing glycolic acid, be sure to do a local skin test. Apply a small amount of product behind the ear or on the inside of the wrist and wait for 24-48 hours. If there is no abnormality such as allergy or redness, it can be used normally. Due to the large differences in individual skin, some people's skin has poor tolerance to glycolic acid. Testing in advance can effectively avoid the risk of allergies.
Furthermore, the frequency of use should not be careless. Initially use glycolic acid-containing products, the frequency should be low, 1-2 times a week, and gradually increase to 3-4 times a week after the skin adapts. Do not rush for success, use too frequently, so as not to damage the skin barrier and make the skin fragile and sensitive.
Again, it is very important to do a good job of sun protection. Glycolic acid will thin the stratum corneum of the skin and reduce its resistance to ultraviolet rays, so during use, sun protection must be comprehensive. When going out during the day, you should apply a high-multiple sunscreen. At the same time, with the help of hard sunscreen methods such as umbrellas, sun hats, sunglasses, etc., to prevent sunburn and tanning of the skin and reduce the risk of photoaging.
Finally, you need to be cautious when matching with other ingredients. Glycolic acid is acidic and may interact when mixed with certain ingredients. For example, it should not be used in combination with ingredients that are also highly irritating, such as high-concentration salicylic acid and retinoic acid, otherwise the burden on the skin will increase sharply and it is easy to cause adverse reactions such as allergies. If you need to match other products, it is best to consult
What are the contraindications of Glycolic Acid with other ingredients?
Glycolic acid, that is, glycolic acid, has many taboos in various formulas, which must be observed.
First, it is contraindicated with alkali substances. Glycolic acid is acidic, and if it encounters alkali, such as sodium hydroxide and other strong bases, it will neutralize. This reaction is violent, not only makes the efficacy of glycolic acid completely lost, but also generates a lot of heat, causing the system to be unstable, and even the safety is at risk. The classic book "Chemical Compatibility General Review" says: "When acid and alkali encounter, neutralization is present, and the efficacy is destroyed, and heat is generated and endangered."
Second, be careful when it is compatible with certain metal ions. Such as iron ions, copper ions, etc. Glycolic acid can be complexed with such metal ions, causing the color and stability of the solution to change. Looking at past experiments, when glycolic acid meets iron ions, the solution is often brown, and its properties gradually change with time, which is not good for product quality.
Third, it is in phase with strong oxidants. Glycolic acid has a certain degree of reductivity. If it encounters strong oxidants such as potassium permanganate and hydrogen peroxide, it is easy to be oxidized. Once oxidized, its chemical structure changes, and the original skin care, cleaning and other effects do not survive. The ancients said: "Each thing has its own nature, strong oxygen and weak acid are contradictory and incompatible."
Fourth, it should be compatible with protein ingredients. The acidic environment of glycolic acid or protein denaturation. Take egg white as an example, when placed in a solution containing glycolic acid, it can be seen that the egg white has solidified, which is a sign of protein denaturation. In cosmetics and other formulations, if there are protein active ingredients, which are compatible with glycolic acid, its activity may be damaged and its original benefits may be lost.
Therefore, where glycolic acid is used in the formula, the other ingredients must be carefully reviewed to avoid its taboos, so as to achieve the desired effect.
What is the Optimal Frequency of Use for Glycolic Acid?
Glycolic acid is glycolic acid. The optimal frequency of use is uncertain, and it depends on many factors such as skin characteristics, purpose of use, and product concentration.
If it is well tolerated by the skin and wants to improve mild skin problems, such as dull complexion and keratin accumulation, you can use a lower concentration (such as 2% - 5%) glycolic acid product 1 to 2 times a week at the beginning of use. When the skin gradually adapts, the frequency can be increased to 3 to 4 times a week.
If the skin is more sensitive, the initial stage should be more cautious, once every two weeks is appropriate, and close attention should be paid to the skin reaction. If the skin does not feel uncomfortable during use, slowly increase the frequency of use.
If using high-concentration glycolic acid products (more than 10%), it is usually recommended to use 1 to 2 times a month, because it is highly irritating to the skin, frequent use can easily cause skin damage, causing redness, swelling, tingling and other adverse reactions.
When using glycolic acid products, be sure to do a good job of skin moisturizing and sun protection, because it will make the skin more sensitive to ultraviolet rays. And the product instructions should be strictly followed. If there is an abnormal condition of the skin, you should immediately stop using it and consult a professional dermatologist. In this way, according to your own skin condition, you can reasonably control the frequency of use, so that you can not only reap the effect of glycolic acid skin care, but also protect skin health.
