Skincare for Oily Skin

Oily skin produces excess sebum due to overactive sebaceous glands — often triggered by hormones, genetics, humidity, or the counterintuitive effect of over-cleansing. The goal of an effective oily skin routine is not to strip oil entirely, which triggers a rebound effect, but to regulate sebum production, keep pores clear, and create a balanced environment where breakouts are less likely to form.

What to look for

• Niacinamide — regulates sebum production without drying
• Salicylic acid (BHA) — penetrates pores to clear congestion
• Zinc — controls oil and has anti-inflammatory properties
• Clay ingredients — absorb excess sebum without disrupting the barrier
• Lightweight gel or water-based moisturisers — hydration without heaviness

What to avoid

• Heavy cream moisturisers — can clog pores on oily skin
• Alcohol-based products — cause rebound oiliness by over-drying
• Skipping moisturiser — dehydrated oily skin overproduces sebum to compensate
• Pore strips — temporarily clear but damage the pore lining long-term

Frequently Asked Questions

Does oily skin still need moisturiser?

Yes. Oily skin and dehydrated skin are not mutually exclusive — many people with oily skin are also dehydrated at the skin surface. Skipping moisturiser causes the skin to overproduce sebum to compensate for the lack of hydration. Lightweight, oil-free gel moisturisers provide the hydration oily skin needs without adding to the oil load.

Why does my skin get oilier when I use certain cleansers?

Harsh, stripping cleansers remove not just excess sebum but also the skin's natural lipid barrier. In response, the sebaceous glands compensate by producing more oil. Switching to a gentle, pH-balanced cleanser — even one that doesn't feel squeaky clean — is often the single most effective change for reducing long-term oiliness.

Can diet affect oily skin?

Yes. High-glycaemic foods — white bread, sugary drinks, processed snacks — spike insulin, which in turn stimulates androgen hormones that increase sebum production. Dairy has also been linked to increased sebum in some individuals. Reducing refined sugars and processed foods can have a meaningful impact on oil levels and breakout frequency over several weeks.
