Usage of heptanoic acid
If you want to make good use of heptanoic acid, you must understand the method. Cleanse the face first, so that the skin is clean and scale-free, so that it can be absorbed easily. Apply an appropriate amount of heptanoic acid lightly to the face, avoiding the eyes and lips, because the skin is delicate and easily irritated.

Apply slowly and evenly when applying, and those who are new to it may feel slightly prickly. This is normal and a sign of skin adaptation. If the tingling is unbearable, quickly wash off with water.

For the first time, you can apply it every day. When the skin gets used to it, it can be gradually increased to once a day. And after use, you need to protect yourself from the sun, especially during the day. It is appropriate to apply sunscreen

After each use, check the state of the skin. If there is any discomfort, stop and consult a doctor. Using this method, heptanoic acid may help the skin rejuvenate and obtain a delicate and smooth effect.
