Pudvi Kaka, Chief Scientific Officer at DECIEM, spoke to Byrdie about the causes of oily skin and the best The Ordinary products to use to combat the effects.

Kaka told the outlet: "Oiliness of skin occurs when oversized sebaceous glands produce excessive amounts of sebum, resulting in the appearance of shiny skin and visibly enlarged pores." To combat this oiliness, "it is best practice to regularly cleanse the skin using a gentle cleanser that will not cause a disruption to the epidermal barrier or excessively strip the skin of its natural surface lipids and moisture." 

The Ordinary's products are designed to reduce excessive sebum production while refining skin's texture and helping to mattify skin tone, without "starving" the skin of hydration or causing dryness. The first product that Kaka recommends for oily skin is The Ordinary Niacinamide 10% + Zinc 1%, $7, which should be applied as the first step of a morning skincare routine. This should then be followed by applying The Ordinary Natural Moisturizing Factors + HA cream, also $7, to the face as the second step in the routine. For evening skincare, Kaka recommends using The Ordinary Salicylic Acid 2% Solution as a one-step solution to combating oil skin.
