"Guide to the Use of a Certain Acid 7"

Those who want to make good use of a certain acid 7 should understand the method and follow the path to obtain its benefits and avoid its harm.

The first thing to know is the nature of the skin. If the skin is sensitive and weak, it is advisable to try it in a small place first to see if it is uncomfortable. Take a small amount of acid, apply it to the wrist or behind the ear, and wait for two or two hours. If there is no redness, swelling, itching, or pain, it can be gradually applied to the face.

When using, clean and dry the face, dip the pulp of your finger in an appropriate amount of a certain acid 7 liquid, and apply it lightly to the face, avoiding the eyes, lips, and tender parts around the nose. For the first time, it may feel slightly prickly. This is a sign of skin adaptation, so don't be afraid. However, if the tingling is unbearable, wash it with water as soon as possible and use it slowly.

For the first time, it should be thin and less, and gradually increase the amount. You can use it every three or five days, and wait for the skin to get used to it, and then increase it to every other day, but it should not be used too often. And after use, you need to take care of the skin and apply gentle skin care products to prevent it from drying. Especially when you are heavily protected against the sun during the day, this acid can increase the sensitivity of the skin to light. If you are accidentally exposed to the sun, it is easy to cause pigmentation.

Although a certain acid 7 is a good skin care product, it cannot be used properly and will hurt the skin. Therefore, the user should be careful, according to the change of the skin, timely change its usage and dosage, so that the skin can be rejuvenated.
