Which has fewer side effects, salicylic acid or fruit acid?

Fruit acid is small, and salicylic acid is generally not used.

Do you still need to ask? of many people are laymen.

Salicylic acid is a natural compound extracted from willow bark.

AHAs don't have to be natural.

The professional conclusion is, of course, that salicylic acid is safer than fruit acid.

Don't think that fruit acids come from fruits.

The differences between salicylic acid and fruit acid and azelaic acid are as follows:

1.**Different: Salicylic acid is a fat-soluble organic acid derived from willow bark; Fruit acids are extracts from fruits; Azelaic acid is an acid extracted from substances such as barley and wheat.

2.The effect is different: after applying salicylic acid on the face, it can relieve the symptoms of acne when there is acne on the face, and long-term use can improve the problem of acne scars; After applying AHAs on the face, it can penetrate deep into the dermis layer of ** to shrink pores, remove blackheads and soften the stratum corneum; Azelaic acid can inhibit and kill various aerobic and anaerobic bacteria in acne, and has become the preferred over-the-counter drug for acne.

3.Different acidity: salicylic acid is more acidic than fruit acid; Azelaic acid is comparatively the weakest acidity.

Since salicylic acid has been staying on the surface, it is more acidic, and the content needs to be strictly controlled when using salicylic acid, otherwise it may cause symptoms such as peeling and itching, which is safer in comparison.

I hope the above information is helpful to you, and if you have any other questions, welcome to let me know.

Many people know that brushing acid can improve the state, but they don't know what the effects of various acids are, and they don't know which acid their skin is suitable for. Then salicylic acid.

and fruit acids and azelaic acid.

The difference, which is more acidic, fruit acid or salicylic acid?

Salicylic acid and fruit acid and azelaic acid are all extracted from different items, fruit acid is an acid extracted from fruits as the name suggests, salicylic acid is a fat-soluble organic acid, and azelaic acid is an acid extracted from substances such as barley wheat. The roles of these three acids are also different, and the differences between the three acids are described below

1. Salicylic acid: Because the salicylic acid molecule is large, it can only play a role in the epidermal layer, applying salicylic acid when acne on the face can alleviate the symptoms of acne, and long-term use of salicylic acid can also improve acne scars.

problems. 2. Fruit acid: The molecular composition of fruit acid is relatively small, after applying fruit acid on the face, the fruit acid will penetrate deep into the dermis layer, thereby improving the skin texture to shrink pores, remove blackheads and soften the stratum corneum.

3. Azelaic acid: Azelaic acid can inhibit and kill acne.

Various aerobic bacteria and anaerobic bacteria.

It has become ** acne.

The over-the-counter drug of choice, long-term use can help to remove acne and reduce the appearance of acne.

Salicylic acid is more acidic than fruit acid. Since salicylic acid has been staying on the surface, it is more acidic than fruit acid, and the content of salicylic acid needs to be strictly controlled when using salicylic acid, otherwise it may cause symptoms such as peeling and itching, which is safer in comparison.

1. Fruit acid, AHA is extracted from fruits and yogurt, so it is also called "fruit acid". Its relative molecular weight from small to large is glycolic acid, lactic acid, malic acid, tartaric acid, and citric acid. Glycolic acid has the smallest molecular weight, the strongest permeability, and is more suitable for chemical peeling preparations, which has little damage and has the effect of improving skin tone and skin rejuvenation.

2. Salicylic acid, BHA salicylic acid is a white crystalline powder, which exists in willow bark, white bead leaves and sweet birch trees in nature. Salicylic acid is widely used, eczema, ringworm, acne, psoriasis, dandruff may be used, the concentration is 3-6% for exfoliation, higher than 6 is destructive to tissues. Concentrations below 40 are suitable for corns, plantar warts, etc.

Salicylic acid can also be added to acne and anti-dandruff medications.

Extended Information: Chemical Peel Preparation:

When you decide to use a chemical peel, in order for your skin to adjust to the high concentration of AHAs for the best results, you should start your daily skincare routine as follows:

1. One to two weeks before peeling, you should start using AHA maintenance cream (or lotion, or gel), and use it once at night after washing your face to make your facial skin adapt to AHA.

2. Patients with dark spots should use sunscreen lotion (SPF 15 or above 15) every morning to avoid sun damage, and use it again at noon under the sun.

1) Facial beauty or face-making;

2) Perm and dye hair;

3) Shaving and hair removal;

4) Use scrubs;

5) Use A acid product on the face;

6) Excessive swimming, sunburn face;

4. Before peeling, you need to inform the doctor whether there are any of the following symptoms:

1) Allergic** or immune diseases;

2) Facial diseases (such as eczema, allergitis);

3) Excessive sensitivity to sunlight;

4) Whether you smoke or not;

5) Facial injury;

6) Viral infections (such as labial rashes, flat warts);

7) Whether you are taking medication;

8) Whether you are allergic to alcohol;

5. On the day of skin peeling, please wash your face first, do not wear makeup, shave your face, use perfume or cologne, etc.

Salicylic acid is a fat-soluble organic acid with the chemical formula C7H6O3. The appearance is a white crystalline powder. Whereas, AHAs are various organic acids extracted from fruits and are active ingredients found in a variety of natural fruits or yogurts.

Fruit acids can be divided into 37 kinds according to their molecular structures: glycolic acid, lactic acid, malic acid, tartaric acid, citric acid, mandelic acid, etc., but in the medical cosmetology industry, the most commonly used ingredients are glycolic acid and lactic acid. Glycolic acid, also known as sugarcanic acid and ethylene glycolic acid, was first extracted from sugarcane and is the most widely used member of fruit acid products.

AHAs and salicylic acids work differently.

Fruit acid is an organic acid extracted from fruits, which can generally penetrate deep into the dermis, and salicylic acid is a fat-soluble organic acid that can only stay in the stratum corneum.

Fruit acids are usually the first generation of fruit acids, which refer to a series of organic acids in fruits, so they are called fruit acids, including glycolic acid in sugarcane, lactic acid in fermented dairy products, malic acid in apples, citrus acid in citrus, and mandelic acid in almonds.

Salicylic acid, also known as o-hydroxybenzoic acid, is found in willow bark, poplar leaves and sweet birch trees in nature, so it is also called salicylic acid. Some people refer to salicylic acid as BHA, which is derived from the imitation of fruit acids.
