“What causes acne? What are the types? How to solve acne problems effectively!

Whether in the past or present, acne has always been a top skin concern for everyone. This includes acne on the face, body, or even in hidden areas. All of these acne issues significantly impact confidence in daily life.

Especially in today's era with increased smartphone and computer usage, and more cameras being used, acne is becoming even more apparent.

Many people try to treat acne themselves in every way, such as applying creams, spot treatments, squeezing pimples, and cleansing their faces thoroughly, but why doesn't the acne disappear? Sometimes, it even gets worse than before.

The cause may be that our treatment methods do not match the type of acne we have. Therefore, today I will introduce everyone to the types of acne so that everyone can know the correct treatment methods in time to prevent an increase in acne.

Clogged pores

What are clogged pores? What causes them?

Comedones are pimples that form due to clogged oil glands under the skin. This happens when the oil glands produce an excessive amount of oil, which then clumps together with abnormal skin cells or with dirt in the hair follicles, such as dust particles or makeup, causing a blockage. Comedones are not inflamed, but they remain under the skin, which can cause irritation when you have them.

What's the difference between whiteheads, blackheads, and blind pimples?

Whiteheads or closed comedones

Many people often confuse this type of acne with inflammatory acne. However, whiteheads are smaller in size and have a small white, hardened bump at the center, which is filled with sebum. Sometimes, they may appear the same color as the skin. This type of acne can become inflamed if squeezed, pressed, or picked at improperly.

Blackheads or open comedones

This type of acne is easy to spot. You can observe a black lump in the center of the eruption. It develops from whiteheads that have been left untreated for a long time, until the head of the pimple is exposed to the air. This causes oxidation, turning it black. Blackheads must be pushed or squeezed out. However, if you push or squeeze them incorrectly, it can cause inflammation, and if left for too long, it can lead to acne scars.

Acne without a head, or closed comedones

Whiteheads are non-inflammatory clogged pores that cannot be seen and are not visible to the naked eye. They may cause pain or tenderness when touched and can occur naturally due to increased androgen hormones during adolescence and before menstruation. This hormonal imbalance leads to overproduction of sebum, resulting in whiteheads.

Acne can occur in which areas?

Blackheads can occur all over the body, most commonly on the cheeks, jawline, and other areas such as the chin, forehead, and back.

What is the treatment for clogged pores? What should I use?

Comedonal acne treatment can be done in 4 main ways:

Squeeze pimple The advantage is that it can quickly bring out pimples. However, if the pimple is not completely squeezed out or is squeezed incorrectly, it can cause increased inflammation and even increase the risk of acne scars. Therefore, it is recommended to have a specialist extract the pimples to prevent potential risks.

Ointment Acne treatments, or spot treatments for acne, generally contain compounds that help reduce excess oil around the acne or inhibit bacterial growth on the skin, causing the acne to subside.

You should consult a specialist doctor or pharmacist before choosing to buy any medication, because if you choose a medication that is not suitable for your acne problem, you may not see results or it could worsen your acne.

Take medicine Suitable for those with a large number of both comedonal acne and inflammatory acne, as taking medication for comedonal acne will also treat those with concurrent inflammatory acne. The medication works by regulating hormones that stimulate acne or oil production, causing them to decrease and become more balanced, thus reducing acne. However, when purchasing medication to take, one must be cautious of potential side effects. It is best to consult a specialist physician for prescription and dispensing of medication.

Acne injection ー An injection into the pimple can reduce the inflammation. This method is suitable for those with large cystic acne or nodular acne. To prevent recurrence, the pimple head should be extracted first, and treatment should include topical acne medication and oral medication, all under the supervision of a specialized physician.
