1 What is Mandelic Acid?
Mandelic Acid is also called mandelic acid, a fat-soluble acid with a larger molecular weight than the first generation of fruit acids; it is extracted from the hydrolysis of bitter almonds. Mandelic Acid can improve the affinity of the skin and dissolve blackheads, and accelerate the metabolism of old keratin and improve enlarged pores for acne caused by blockage caused by Propionibacterium acnes. It is milder and less irritating than salicylic acid.
2 Effects of Mandelic Acid
Remove closed pores: When pores are blocked by keratin and excess oil, blackheads and whiteheads are formed. Mandelic Acid has excellent exfoliation and can dissolve the oil and keratin that clogs the pores, achieving the effect of cleaning and unblocking pores, and effectively removing acne and closed pores.
Remove keratin: Mandelic acid removes keratin. The keratin on the face is relatively thick or the keratin metabolism is slow. If the pores are blocked and cause acne, you can use mandelic acid to clean the old keratin of the skin and make the skin smooth.
Clean pores: Slow skin metabolism can make the skin rough. Using mandelic acid can promote skin metabolism and help unclog pores.
3 Advantages of mandelic acid
1.Mandelic acid is the only fat-soluble fruit acid, which can effectively unclog pores and solve the problem of blackheads.
2.Gentle and non-irritating: Mandelic acid is also a large-molecule fruit acid, which has less residual stimulation to the skin than other acids. When combined with soothing ingredients such as red vitamin B5 or Centella asiatica, it will produce a 1+1>2 effect.
3.Mandelic acid can improve acne marks and enlarged pores, and can act on the shallow, middle and deep layers of the skin. How to choose the concentration and use of mandelic acid.
4 How to choose the concentration?
1. Low concentration 3%-10%: It promotes the shedding of the aging stratum corneum, is gentle and suitable for all skin types, but for acne and severe skin problems, the improvement effect is less significant.
2. Medium concentration 10%-20%: accelerates the renewal rate of keratin and a small number of upper epidermal cells, and is closer to the pH value of the skin, which can improve the whole face or key local problems.
3. High concentration above 30%: strengthens the promotion of new cell generation, is fast and more stimulating, and focuses on strengthening serious skin problems, but it is not suitable for all skin conditions. It is more often in the category of medical beauty treatment and is not recommended for home care products.
5 Precautions for use
1. When using mandelic acid for the first time, you need to start with a low concentration, and it is best to use it at night. The skin stratum corneum is thinner after acid brushing, so you must pay attention to sun protection during the day.
2. The number of times used per week should be gradually increased according to the skin's tolerance. After establishing tolerance, you can use it every day. Acid-containing products should not be used for a long time. Use it for one or two months and stop for a period of time.
3. Be careful not to use it in combination with other acids. It is not recommended to use mandelic acid products after using exfoliating or cleansing masks.
