A acid has a certain effect on skin diseases. For example, if you often have acne on your face, you can use A acid to apply it. Let’s see whether A acid is a prescription drug or an over-the-counter drug? What are the differences from salicylic acid:

Is A-acid a prescription or over-the-counter drug?

Acid is a prescription drug. This means that you need a doctor's prescription to buy it at a pharmacy. You should also be careful when using it and follow the doctor's instructions. Don't use it casually, as it will damage the skin.

When purchasing A acid, you should choose a regular brand. After all, it is in direct contact with the skin. If the skin is damaged, it will be irreversible. When using A acid, you should choose to use it at night. A acid is afraid of light, so you should start using it at a low concentration. It takes time for the skin to adapt to A acid.

Of course, not everyone can use A acid. It is not suitable for people with sensitive skin, damaged skin barrier, or thin skin. If your skin experiences unbearable stinging, redness, and swelling after using A acid, you should stop using it. Pregnant women should not use A acid as it can easily cause harm to the fetus.

The difference between a acid and salicylic acid

1. Alpha acid

A acid needs to be protected from light when in use and can be used once every night. Many people experience stinging pain when they first use A acid. When you first use it, you can mix A acid and facial cream in a 1:1 ratio and then apply it on the acne. Using A acid for one month can cure 10% of acne. It will take 4 to 6 months to achieve good results, and 80% of acne can be cured in 8 months.

A acid does have a strong therapeutic effect on acne, but its side effects are very strong and it should be stopped in the first three months of pregnancy.

2. Salicylic acid

Salicylic acid can exfoliate, kill bacteria, reduce inflammation and remove acne. The ingredient is extracted from willow bark and is a relatively natural anti-inflammatory drug. Many acne-removing products contain salicylic acid, with concentrations ranging from 1.5% to 2%.

Salicylic acid can also be used together with fruit acid. Together, it can whiten the skin, make it more delicate, improve wrinkles and shrink pores. It is widely used in the medical beauty industry now. Salicylic acid can last for 12 hours under low pH conditions, which reduces the irritation of salicylic acid. The 30% supramolecular salicylic acid used in medical institutions is generally 4 to 5 times a course of treatment.

Regarding A acid, it is indeed a prescription drug and you need a doctor's prescription to buy it. Low-concentration salicylic acid can be used at home and is available for purchase.

Which is better, retinoic acid or salicylic acid?

Salicylic acid cream is used to treat psoriasis, superficial fungal diseases of the skin, seborrheic dermatitis, acne, corns, warts and calluses. This product can cause contact dermatitis. After large-area use and absorption, symptoms of systemic salicylic acid poisoning may occur, such as dizziness, confusion, shortness of breath, persistent tinnitus, and severe or persistent headaches.

Retinoic acid cream is used to treat acne vulgaris, especially blackhead acne skin lesions, senile, solar or drug-induced skin atrophy, ichthyosis and various abnormal keratinization and hyperpigmentation skin diseases, and psoriasis! External use of this product may cause skin irritation symptoms such as burning, erythema and desquamation, which may make the skin lesions more obvious, but at the same time it shows that the drug is working and is not aggravating the condition. The skin can usually adapt and tolerate the treatment, and the irritation will gradually disappear. If the irritation persists or worsens, you can take the medication intermittently or stop taking it under the guidance of a doctor! It is contraindicated for women during the first 3 months of pregnancy. You can refer to the medication!
