Spots are a bad phenomenon for most women, and whitening and freckle removal are very important for many women. In our daily lives, we are used to using various whitening and freckle removal products. However, with the development of medicine, there is a method called fruit acid freckle removal. So, do you know about fruit acid freckle removal? Do you know the methods and precautions of fruit acid freckle removal? Let's take a look together.
I think many people are not very familiar with fruit acid freckle removal. The key to fruit acid freckle removal is the extraction of fruit acid. So, do you know what fruit acid is?
Fruit acid
Fruit acid is a group of chemically similar compounds extracted from plants, which can be divided into three categories: α-hydroxy acids (AHA), β-hydroxy acids (BHA), and α and β-hydroxy acids (BF).
Classification of fruit acid
①α-hydroxy acid
It is a weak acid that can be found in many foods. AHA refers to the presence of hydroxyl groups at the α position, and it has two effects: moisturizing and anti-keratinization. Additionally, they have found that when used continuously for up to 10 months, it can reduce fine lines on the face.
②β-hydroxy acid
Also known as plant acid, it is extracted from willow bark and wintergreen leaves, also known as salicylic acid or star fruit acid. Due to the lipophilic nature of BHA, it can penetrate deep into the pores and lipid-rich stratum corneum, exerting antioxidant effects and clearing accumulated sebum and blackheads in the pores, reducing the occurrence of acne.
In terms of preventing acne and reducing blackheads, BHA is more effective than AHA. Additionally, BHA is stronger than AHA in terms of irritability, stability, and sensitivity. The concentration of BHA for exfoliation is between 20% and 30%.
Effects of different fruit acids on the skin
①Low concentration fruit acid (less than 10%)
Fruit acids can reduce the cohesion between epidermal keratinocytes, remove aging keratin, improve roughness, dullness, and regulate skin texture.
②Moderate concentration fruit acid (10%-30%)
Fruit acid can reach the dermal tissue and has good effects on acne, lightening dark spots, and smoothing wrinkles.
③High concentration fruit acid (greater than 30%)
High concentration fruit acid has very strong penetration ability and can peel off aging keratin, accelerating the effect of freckle removal. However, this type of fruit acid belongs to the nature of skin resurfacing, so it is necessary to seek treatment from a professional doctor.
Methods to say goodbye to spots
1. Wrap your head with a towel, and pay attention to wrap your ears as well to prevent the fruit acid from flowing into your ears. Then, wash your facial skin with special cleansing products to remove makeup, dust, and oil according to the normal method.
