First: what kind of acne do you have?
Clogged pores, blackheads and small bumps behave differently from red, inflamed, painful spots, and both behave differently from the deep, slow cysts along the jaw that flare on a monthly cycle. They are not stages of the same thing and they do not respond to the same approach.
This is why the first session anywhere sensible is a look at your skin under magnification rather than a treatment. If somewhere sells you a ten-session package before anyone has looked closely, that is a sales process, not a plan.
How a course is usually spaced
Skin cells take roughly a month to work their way to the surface, so sessions are commonly set one to two weeks apart and judged over a couple of months rather than a couple of visits. Mild acne commonly needs around three sessions before the change is obvious; moderate acne tends to run four to six, and persistent or inflamed acne five to seven. The honest answer at the start is a range rather than a number.
Between sessions matters as much as the sessions. What you use at home, whether you finish a course of anything prescribed to you, sleep and stress all move the result — and none of that is under a therapist's control.
Why the first change is slow
A spot you can see today started forming under the surface weeks ago, and new ones keep arriving while the skin settles. Expect at least six to eight weeks of steady care before breakouts start to fall. Week two is the point where people give up, and it is too early to judge.
A studio that tells you this beforehand is being straight with you. One that promises smooth skin after a single facial is not.
When acne needs more than skincare
Mild acne often responds to a steady routine: gentle cleansing, over-the-counter actives such as benzoyl peroxide or adapalene, and supporting sessions such as extraction, peels and light-based care. That covers much of what people walk in with.
Deep cystic acne that is painful and leaving scars is a different problem. It usually needs prescription medication, which means a hospital dermatology department. If that is what you are dealing with, say so at the first consultation — a straight answer about what will and will not help is worth more than a course that was never going to be enough.
What it costs
Single sessions and courses are both common. CHAMING publishes every price on the site rather than quoting only in person, so you can compare before booking. The consultation itself, including the skin scan, is free and carries no obligation to buy a course.
Practical notes for a first visit in Hanoi
- Come with a bare face if you can — makeup has to come off anyway.
- Bring, or photograph, anything you are currently using on your skin, including anything prescribed at home.
- Say if you are on isotretinoin or have been in the last six months. It changes what is safe to do.
- Allow a little more time than the treatment itself for the consultation on a first visit.
