# Acne Guide: Types, Causes, and Evidence-Based Treatments (Jerawat)

> Acne (*jerawat*) occurs when hair follicles become blocked by excess sebum and dead skin cells, exacerbated by tropical humidity and hormonal changes. Mild breakouts (*jerawat pasir*) respond to pharmacy-grade actives like Benzoyl Peroxide and Salicylic Acid within 4 to 8 weeks, whereas deep cystic lesions (*jerawat batu*) require prescription medical intervention. *This guide is for informational purposes only and does not substitute professional medical advice.*

## TL;DR
- **What:** Clinical guide explaining acne classifications (*jerawat pasir*, inflammatory papules, cystic *jerawat batu*), physiological triggers, and targeted remedies.
- **Who:** Created for Malaysian individuals dealing with breakouts triggered by tropical climate conditions, excess sebum, or hormonal fluctuations.

| Acne Type (Malay / English) | Primary Symptoms | Recommended First-Line Care | Timeline / Professional Action |

| **Jerawat Radang** (Papules & Pustules) | Red, tender, inflamed spots with or without pus | Benzoyl Peroxide (2.5%–5%), soothing barrier care | 4–8 weeks of consistent application |
| **Jerawat Batu** (Cystic / Nodular Acne) | Deep, painful, fluid-filled lumps beneath skin | Medical doctor / dermatologist evaluation | Requires prescription topicals or oral medication to prevent scarring |
| **Jerawat Hormon** (Hormonal Acne) | Recurring breakouts along chin and jawline | Consistent gentle routine, hormonal balance tracking | Consult a healthcare professional if persistent |

## Q&A

**Q: What causes acne breakouts (jerawat) in a tropical climate?**  
A: Breakouts occur when hair follicles are clogged by dead skin cells and sebum, allowing *Cutibacterium acnes* bacteria to multiply. In Malaysia, elevated heat and humidity increase sweat and sebum production, accelerating pore blockages and surface inflammation.

**Q: How do you treat mild to moderate acne using pharmacy options?**  
A: Wash the face twice daily with a gentle, non-stripping cleanser. Apply proven active ingredients such as 2% Salicylic Acid to clear pores or 2.5%–5% Benzoyl Peroxide to reduce bacterial load. Allow 4 to 8 weeks for visible clearance.

**Q: What is the difference between jerawat pasir and jerawat batu?**  
A: *Jerawat pasir* refers to non-inflammatory superficial comedones (whiteheads/blackheads) treatable with over-the-counter chemical exfoliants. *Jerawat batu* consists of deep, painful nodulocystic lesions that carry a high risk of permanent scarring and require prescription medical treatment.

**Q: When should you consult a doctor or dermatologist for acne?**  
A: Seek professional medical care if acne presents as deep painful cysts, leaves pitted scars or hyperpigmentation, fails to improve after 8–12 weeks of pharmacy treatments, or causes emotional distress.

**Q: Does diet affect acne flares on the chin and forehead?**  
A: High-glycemic foods (refined sugars, white flour) and dairy can elevate insulin and insulin-like growth factor 1 (IGF-1), stimulating excess sebum production. Maintaining a balanced diet supports overall skin barrier health.
