DL-Mandelic acid is a different kind of AHA. It is fat-soluble, has a large molecular weight, and has deeper penetration. Therefore, the irritation during use is much lower than that of AHA. Therefore, in general, the concentration of DL-Mandelic acid products on the market is higher than that of AHA. Generally speaking, less than 20% of DL-Mandelic acid is safe, and the overall effect is quite expected.
What kind of skin is suitable for using mandelic acid?
- Rough dullness with slow keratin metabolism
Some people have different rates of keratin metabolism, making their skin rough and dull. In this case, using mandelic acid essence can help exfoliation of keratin.
- Pores are blocked by keratin
This refers to comedones and acne. When the hair follicle epithelium is hyperkeratized, and the keratin is accumulated in the hair follicle after exfoliation, acne will occur. In this case, the mandelic acid essence is considered to be the most lipophilic among AHA. It can help dissolve the keratin in the hair follicle and relieve the trouble of continuing to accumulate acne.
- Treatment of pigment spots and severe acne
With high acidity and high concentration of mandelic acid extract, the risks and effects can be regarded as medicines. The management methods are the same as AHA and belong to the scope of doctors. Therefore, to solve the problem of spots and acne, going to the hospital for a mandelic acid peeling treatment is the right way.
DL-Mandelic acid can actually be classified into AHA, but the only fat-soluble AHA, because its molecular weight is larger than glycolic acid, and its penetration rate is lower, so it is less irritating. It not only has AHA properties but also has whitening and antibacterial effects. Although mandelic acid has a very high affinity with the skin, it has a certain effect on skin rejuvenation, but if it is not used within a safe range, or if excessive acid is used, it may cause skin burns, peeling, redness, swelling, itching, etc.
Even if it is operated by a professional doctor in a professional institution, the following matters need to be paid attention to:
- Do not bleach, wax, massage, scrub, depilate, etc. 1 week before using DL-Mandelic acid.
- Sunscreen should be taken seriously before using DL-Mandelic acid, which can effectively reduce postoperative pigmentation.
- After using DL-Mandelic acid, avoid contact with water within 24 hours of the peeling site. After that, normal cleaning, moisturizing, and sun protection can be performed.
- People with skin allergies or bacterial or viral infections on the face (such as herpes simplex) should use DL-Mandelic acid with caution
- Do not use DL-Mandelic acid for the time being if you have recently undergone surgery (there is a wound that is healing) or have recently received radiotherapy
