Comprehensive Acne Treatment — Siam Dermatology Samut Prakan

Acne (Acne Vulgaris) is a skin problem that can appear at any age, not only in teenagers. Effective acne treatment starts with understanding that acne has several causes working together, and that all of them need to be addressed at the same time. At Siam Dermatology we provide complete acne care, from clogged pores, inflamed acne and hormonal acne to acne marks and acne scars. This article explains the causes, the types of acne and the treatment options provided by a specialist dermatologist.

What causes acne?

Acne is caused by 4 main factors working together. Effective treatment therefore has to address all 4 factors at once, not just one.

• Excess oil: the oil glands produce too much sebum.

• Clogged pores: skin cells block the inside of the pores.

• Bacteria: C. acnes bacteria multiply.

• Inflammation: the skin becomes inflamed, with red bumps or pus.

Types of acne we treat

• Clogged pores: blackheads and whiteheads (Comedonal acne)

• Inflamed acne: red bumps or pus (Inflammatory acne)

• Hormonal acne: seen in women around their period, with PCOS, or after stopping birth control pills

• Cystic acne: deep, large acne (Cystic acne) that needs prompt treatment because it can leave acne scars

• Acne in other areas: acne on the back, chest and shoulders, and acne from wearing a mask (maskne)

• Acne marks and acne scars: red marks, dark marks and acne scars that remain after acne clears

Our treatment approach

The doctor chooses the method to suit the type and severity of the acne, often combining several approaches.

• Topical medication: Topical retinoid, Benzoyl peroxide, Adapalene, Dapsone and Azelaic acid reduce clogging and inflammation.

• Oral medication: Doxycycline, Spironolactone, birth control pills and Isotretinoin for severe acne or hormonal acne, under a doctor's supervision.

• Procedures: acne extraction, chemical peels, LED light therapy and IPL support the treatment.

• Acne marks and acne scars: Fractional CO2, RF Microneedling, TCA CROSS and Subcision are options for skin rejuvenation.

Please note that some medications, such as Isotretinoin, must be used under close supervision and follow-up by a doctor and should not be bought and used on your own. Cystic acne should be treated promptly to reduce the chance of permanent acne scars.

Frequently asked questions

Can acne go away on its own, and why treat it? Mild acne may improve by itself, but inflamed and cystic acne that is left untreated risks leaving dark marks and permanent acne scars. Early treatment helps reduce long-term problems.

Can I squeeze acne myself? It is not recommended, because it risks spreading the inflammation and causing scars. Clogged pores should be extracted properly by a doctor or a trained specialist.

When will I see results from acne treatment? In general, clear results begin to show within several weeks to several months, depending on the type and severity of the acne. Consistency with treatment is very important.

Can acne scars be treated? They can be improved with procedures such as laser, RF Microneedling or Subcision, but a doctor needs to assess the type of acne scar to choose a suitable method.

Acne that is treated properly and early reduces the chance of permanent marks and acne scars. If you would like a treatment plan suited to your skin, consult a specialist dermatologist at Siam Dermatology Samut Prakan. Call +66 61 448 7000 or LINE @siamderm.
