Perioral Dermatitis
Collapsible content
What Are The Causes?
Excess Sebum Production
Overactive sebaceous glands, stimulated by androgens (male hormones present in all genders), produce excessive oil. This mixes with dead skin cells, forming a plug in the hair follicle.
Abnormal Keratinization
In acne-prone skin, the natural shedding of keratinocytes (skin cells) inside the follicle is altered. These cells stick together instead of exfoliating normally, creating comedones (whiteheads and blackheads).
Cutibacterium acnes (C. acnes) Overgrowth
This skin bacterium thrives in clogged, oxygen-poor follicles. It breaks down sebum into free fatty acids, triggering inflammation and the formation of papules, pustules, and cysts.
Inflammatory Cascade
The immune system reacts to the bacteria and sebum oxidation products by releasing inflammatory mediators (IL-1, TNF-α, IL-8), which cause redness, swelling, and tenderness.
Hormonal Influence
Fluctuations in hormones—especially during puberty, the menstrual cycle, or perimenopause—can upregulate sebaceous activity and worsen congestion.
Other Contributing Factors
-Occlusive skincare or makeup (“comedogenic” ingredients)
-Environmental humidity or sweat
-High-glycaemic diets
-Stress (increases cortisol, which elevates sebum output)
-Certain medications

Night 1- Mild Exfoliation

OR

How Long Before I See Results?
Ensure your skin barrier is strong for at least 2 weeks before introducing more active ingredients like Retinal.
2–4 weeks: Smoother texture, fewer whiteheads.
6–8 weeks: Fewer new pimples, improved clarity.
12+ weeks: Reduced pigmentation, refined pores, improved post-acne marks and scarring.
Skin is slow always to respond fully to treatments so please be patient.
