Please let me know the precautions for high intensity.

Lately, I feel like my facial elasticity has dropped significantly, so I've decided to bite the bullet and get Density High. Since it is a bit pricey, I want to know the precautions beforehand. Are there any specific precautions for Density High that I absolutely must check before the procedure?

In particular, I am curious whether I can wash my face or apply makeup immediately on the day of the procedure, and if the heat sensation tends to last a long time. Since my skin is on the thinner side, I would also like to know in advance how many days redness or swelling lasts after the Density High. If anyone has received this treatment before, please share some aftercare tips or precautions!
