Skin Care Case Study: Acne Management - Cosmetology: Case Studies

Analyze a case study on managing acne, including different treatment options, skincare routines, and lifestyle changes for improving skin condition.

Skin Care Case Study: Acne Management
Purpose: Outline a systematic approach to evaluating and treating acne, highlighting key assessment steps, therapeutic options, and follow‑up considerations.

1. Case Overview

Element	Details
Patient	19‑year‑old college student
Chief Complaint	Persistent facial acne for 12 months; recent flare‑up with painful nodules
Medical History	No chronic illnesses; no current medications; occasional ibuprofen for menstrual cramps
Family History	Mother had adult acne; father has oily skin
Lifestyle	Works part‑time at a gym, sleeps ~6 h/night, diet high in processed carbs, uses a basic foaming cleanser
Psychosocial Impact	Reports low self‑esteem, avoids social events, scores 15 on PHQ‑9 (mild depressive symptoms)

2. Clinical Assessment

2.1 History Taking

Onset & Duration – When did lesions first appear? Any seasonal variation?
Lesion Type & Distribution – Comedones, papules, pustules, nodules, cysts; typical locations (forehead, nose, chin, chest, back).
Triggers – Stress, hormonal cycles, diet, cosmetics, medications, mechanical irritation (e.g., helmets, phone screens).
Previous Treatments – OTC products, prescription meds, procedures; response and side‑effects.
Skin‑care Routine – Cleanser, moisturizer, sunscreen, makeup, shaving practices.
Lifestyle Factors – Sleep, exercise, diet (high‑glycemic foods, dairy), smoking, alcohol.
Psychological Impact – Anxiety, depression, body‑image concerns.

2.2 Physical Examination

Area	Findings
Face	Numerous open comedones on T‑zone, inflammatory papules/pustules on cheeks, 2‑3 tender nodules on chin.
Chest/Back	Scattered papules; no cystic lesions.
Scarring	Post‑inflammatory hyperpigmentation (PIH) on cheeks; no atrophic scarring yet.
Skin Type	Oily, mildly erythematous, no active dermatitis.
Hair & Nails	Normal.
Other	No signs of systemic disease (e.g., hirsutism, virilization).

2.3 Diagnostic Tests (if indicated)

Hormonal panel (free testosterone, DHEAS, LH/FSH) – consider if menstrual irregularities, rapid onset, or refractory acne.
CBC, fasting glucose, lipid profile – baseline before systemic isotretinoin.
Pregnancy test – mandatory before initiating any Category X medication (e.g., isotretinoin, oral tetracyclines).

3. Pathophysiology Recap (Brief)

Follicular hyperkeratinization → comedo formation.
Sebum overproduction (androgen‑driven).
Cutaneous Cutibacterium acnes proliferation → inflammation.
Inflammatory cascade (IL‑1β, IL‑6, TNF‑α) → papules, nodules, cysts.

Understanding these pillars guides targeted therapy.
