Collection: Oily Skin & Large Pores

What causes excessively oily skin? Oily skin occurs when the sebaceous glands produce more sebum than the skin needs. The main driver is hormonal: androgens such as dihydrotestosterone (DHT) stimulate sebaceous gland activity, alongside genetics, hormonal fluctuations, and warm, humid climates. Over-cleansing with harsh, stripping products can also disrupt the skin barrier and trigger rebound oil production.

Why do pores look larger? Peer-reviewed research (Lee et al., Dermatologic Surgery, 2016) identifies three main causes of visibly enlarged pores: high sebum output, reduced elasticity around the pore opening from ageing and sun damage, and increased hair follicle volume. Pores cannot physically open or close, but with the right actives, their appearance can be significantly reduced.

Evidence-Based Actives for Oil & Pores

• Niacinamide: a randomised, double-blind clinical trial found topical niacinamide significantly reduced sebum excretion within 2 to 4 weeks (Draelos et al., Journal of Cosmetic and Laser Therapy, 2006). Found in the Propaira Skin Defence Serum (10% Niacinamide) and 15% Niacinamide Plus Cream.
• Salicylic Acid (BHA): oil-soluble, so it exfoliates inside the pore itself; clinical studies show it reduces congestion, comedones and visible pore size. Found in the Propaira 10% Salicylic Acid Exfoliating Cream and Acne Exfoliating Serum.
• Retinol: peer-reviewed studies show topical retinoids visibly improve pore appearance by stimulating collagen and normalising the pore lining. Found in Dermaceutic Activ Retinol 0.5 and 1.0.
• Glycolic Acid (AHA): clinical trials demonstrate smoother texture and refined pores with regular use. Found in Dermaceutic Foamer 15, Mask 15 and Light Ceutic.

Consistency matters most: visible improvement in oil balance and pore appearance typically takes 4 to 8 weeks of regular use. Browse the complete oily skin and pore care range from Propaira and Dermaceutic below, with free Australian shipping on orders over $99.
