Acne: how it is treated and how long it takes
There are many types of acne, and each type is cared for differently. At Sandee Clinic, Ubon Ratchathani, the doctor first checks which type of acne you have, then chooses a method that suits your skin. Medicine is the main treatment, while extraction, acne injections and light therapy are add-ons.

- Acne starts under the skin. It is not caused by a dirty face, so washing often or scrubbing hard does not help.
- Medicine is the main treatment. Extraction, acne injections, light therapy and IPL are add-ons when the doctor thinks they are needed.
- It takes time. Most people start to see fewer spots after about 6–8 weeks of continuous treatment.
- Do not squeeze or pick your acne, because it can leave marks and scars.
What causes acne

Illustration, left to right
Acne forms in hair follicles (pores), and 4 things happen at the same time.
4 things that cause acne
- The skin makes too much oil
- Pores get clogged with oil and dead skin cells
- Bacteria in the pore multiply
- The skin around the pore becomes inflamed
Acne usually appears on the face, neck and upper body, where there are many oil glands. Things that make acne more likely come from inside, such as hormones and genetics, and from outside, such as some medicines, cosmetics and pollution.
Hormones play a big part, so acne is common in teenagers, and some women break out with their monthly cycle. If your parents had a lot of acne, you are more likely to have it too.
Types of acne

Illustration, left to right
Put simply, there are 3 types. One person may have more than one type at the same time.
Clogged pores
Small, not inflamed, as whiteheads and blackheads. The black color of a blackhead comes from skin pigment, not dirt.
Inflamed acne
Red bumps, or bumps with pus in the middle, that hurt when pressed.
Deep acne lumps
Large, hard lumps deep under the skin that are very painful. Some people call them cystic acne. This type is the most likely to leave marks and scars.
Names people often use, and which group they belong to
- Tiny rash-like bumps (pseudo-acne) Small bumps that come up and go down quickly, usually better within 1–2 weeks with regular skin care.
- Open and closed comedones Small raised bumps, in the clogged-pore group.
- Red raised bumps Firm bumps that hurt when pressed. The doctor may treat some of them with an injection.
- Nodular or cystic acne Large, red, painful bumps. If not treated soon, they may leave marks or scars.
- Milia Hard white heads. Do not squeeze or pick them yourself.
This page is a general explanation. The doctor is the one who tells which type of acne you have.
When to see a doctor

The doctor first checks which type of acne you have, then chooses a method that suits your skin.
Illustration
Many people can manage mild acne on their own, but if any of the points below apply to you, have a doctor take a look.
Check yourself: is it time to see a doctor?
- A lot of acne, or deep, painful lumps
- Marks or scars start to appear after spots go down
- You have cared for it yourself for 4–6 weeks without improvement
- Acne makes you stressed or less confident
The sooner inflamed acne is treated, the lower the chance of acne scars.
Acne treatments at the clinic
The doctor chooses based on the type and severity of your acne. Not everyone needs every option.
Topical and oral medicine

Topical and oral medicine, prescribed by the doctor with follow-up visits
Illustration
This is the main treatment for almost every type of acne. The doctor prescribes it and schedules follow-ups. This page talks about groups of medicines and does not name any drug or brand.
- Apply topical medicine over the whole area where you tend to break out, not just on the spots you can see, because it also helps prevent new spots.
- In the first 2–4 weeks, your skin may be dry, red or peeling. If the irritation is bad, stop and tell the doctor.
- Some medicine groups make your skin sensitive to sunlight, so you must use sunscreen as well.
- For some groups of oral medicine, the doctor prescribes a set course, not longer than needed.
- Some groups of acne medicine must not be used if you are pregnant or planning to have a baby.
Acne extraction

Illustration, left to right
Used for clogged pores, whiteheads and blackheads that have not come out with medicine.
- At the clinic, extraction is done by our staff. It must be done with sterile tools, so do not do it yourself at home.
- Skin looks better quickly, but the effect is temporary, so medicine is needed alongside to prevent new spots.
- Extraction itself can leave marks, so only spots that should be extracted are done.
Acne injection
Used for large inflamed spots that are swollen, red and painful. The doctor injects an anti-inflammatory medicine directly into the spot.
- Most lumps go down within 2–4 days and hurt less.
- Used spot by spot for very painful ones. It is not a way to treat acne over the whole face.
- The skin where you were injected may dip or become thinner, and its color may become lighter or darker. For some people this lasts a long time, so the injection and dose must be done by the doctor.
- Not injected where the skin is infected.
Acne treatments
The clinic has 3 acne treatments. The doctor will recommend one when it suits your skin.
| Treatment | Steps |
|---|---|
| Acne | Extraction → treatment → face mask |
| Acne Light | Acne + blue and red light, to help reduce the bacteria that cause acne and reduce inflammation |
| Acne Sure | Acne + IPL, focused on helping reduce red marks from acne |
See prices on the prices and promotions page.
Light therapy
Visible light is shone on the skin. It suits red inflamed spots, but does not work well on clogged pores or deep acne lumps.
- It is an add-on. Few people clear their acne with light therapy alone, and results differ from person to person.
- It needs several sessions in a row. The doctor will tell you how many after examining your skin.
- You must wear eye covers during the session. Afterward the skin may be a little red, which usually goes away the same day.
- Tell the doctor first if you take medicine that makes your skin sensitive to light.
IPL program
IPL is high-intensity light given in short pulses. It may help mild to moderate acne, but study results do not agree, so it is used as an add-on, not as the main treatment.
- During treatment it feels like a rubber band snapping on the skin. Afterward the skin may be red and sting like sunburn.
- IPL is usually done as a set of 4–6 sessions, 3–6 weeks apart. The doctor will tell you your number of sessions after the exam.
- Less common effects are blistering, or patches of darker or lighter skin. Darker skin and recently tanned skin carry more risk.
- You must avoid the sun both before and after treatment.
- Not suitable if you are pregnant, have recently had strong sun exposure, or take medicine that makes your skin sensitive to light, including some groups of oral acne medicine.
Results vary from person to person.
Which acne usually gets which treatment
This table is only a rough guide. The doctor must always see your actual skin first.
| Type of acne | Usual approach |
|---|---|
| Clogged pores, whiteheads, blackheads | Mainly topical medicine, with extraction as an add-on |
| Inflamed acne, red bumps, pus bumps | Topical medicine, possibly with oral medicine. Some cases add light therapy or IPL. |
| Deep, painful acne lumps | Oral medicine as the doctor prescribes, and acne injections only for swollen, painful spots |
How long treatment takes

Illustration, left to right
Acne can be treated, but no method shows results in a few days. You need to use your medicine regularly and give it time.
Rough timeline
- First 2–4 weeksYour skin may be dry or irritated from the topical medicine, and you may not see fewer spots yet. Do not stop the medicine on your own.
- About 6–8 weeksYou start to see fewer new spots.
- About 2–4 monthsMost medicines reach their full effect.
After the spots go down, most people still need to keep using medicine to stop acne coming back. The doctor will tell you how to continue and when the medicine can be reduced.
Results vary from person to person.
What to tell the doctor before treatment
This information helps the doctor choose medicines and procedures that suit you.
- You are pregnant, breastfeeding or planning to have a baby.
- Medicines and supplements you take regularly, including acne medicines you have used before.
- You have had a drug allergy, or irritation from acne creams.
- You have recently had strong sun exposure, or plan a beach trip soon.
For patients under 18, the doctor decides case by case, and a parent or guardian joins in hearing the treatment plan.
Skin care at home

Wash your face with a gentle product. You do not need many products.
Illustration
Do this alongside your treatment. You do not need many products.
- Wash your face with a gentle product, no more than twice a day.
- Do not scrub or rub your face hard.
- Do not squeeze, pick or scratch your acne, because it makes inflammation worse, can get infected and leaves marks or scars.
- Choose cosmetics and creams labeled as non-comedogenic (not clogging pores).
- Use sunscreen every day. Sunlight makes dark acne marks darker.
If you already have acne marks or scars
Red marks, dark marks and acne scars are each cared for differently, and care should start after your acne has calmed down. Read more on the acne scars and marks page.

Frequently asked questions
Is acne caused by a dirty face?
No. What causes acne is under the skin, so how clean your skin is is not the cause. Washing your face with a gentle product twice a day is enough. Washing often or scrubbing hard may irritate your skin more.
How long does acne treatment take to show results?
Most people start to see fewer new spots after about 6–8 weeks of continuous treatment, and most medicines reach their full effect at about 2–4 months. So do not stop the medicine on your own early on. Results vary from person to person.
Can I squeeze my own spots?
You should not. Squeezing or picking makes acne more inflamed, can cause infection, and risks marks or scars. For clogged pores that will not come out, have them extracted at the clinic with sterile tools.
How many days after an acne injection does the spot go down?
Most lumps go down within 2–4 days. Injections are used spot by spot for large inflamed spots that are swollen and painful. The skin where you were injected may dip or change color, so the injection must be given by the doctor.
My acne has gone down. Can I stop the medicine now?
Ask the doctor first. Most people still need to keep using medicine to stop acne coming back. The doctor will tell you how to continue and when the medicine can be reduced.
I am pregnant. Can I have acne treatment?
Yes, but some groups of acne medicine and some procedures cannot be used during pregnancy. Tell the doctor at your first visit if you are pregnant, breastfeeding or planning to have a baby, and the doctor will choose methods that are safe to use.
Can I send acne photos on LINE before I come?
Yes. Our staff will give first advice and help book a day to see the doctor. Diagnosis and treatment planning are done by the doctor after an exam at the clinic.
Do acne extraction and acne injections hurt?
Most of the time they do not hurt, or hurt very little. Areas where the skin is thin may hurt a little more.
Will extraction leave marks?
There are usually some marks after extraction. Skin treatments and laser for marks can help, so the doctor often recommends doing them together.
How is acne treatment at the clinic different from using creams myself?
At the clinic, the doctor first checks which type of acne you have, then chooses the care steps to suit your acne, including medicine, extraction, acne injections and treatments. Results vary from person to person.
After treatment, will acne come back?
New acne can appear, because there are many factors, such as hormones and genetics. Caring for your skin as the doctor advises helps lower the chance of new acne.
