One of the most persistent skincare myths we encounter in Indian patients with oily skin is the belief that moisturiser is unnecessary — or actively harmful — for their skin type. Oily skin produces excess sebum; adding moisture will make it greasier. This reasoning feels logical but misunderstands what moisturisers do and what oily skin actually needs.
Why Oily Skin Is Often Dehydrated
Oiliness and dehydration are not opposites — they are independent skin parameters. Oily skin produces excess sebum (oil) from the sebaceous glands. Dehydration is a lack of water in the skin cells — a function of the skin barrier and its ability to prevent transepidermal water loss. These can, and very commonly do, coexist. Patients with oily skin who use harsh cleansers, alcohol-based toners, and no moisturiser strip the skin’s surface oils while doing nothing to support water retention — resulting in skin that is simultaneously oily and tight, shiny and flaky. This combination is characteristic of dehydrated-oily skin and is extremely common in Indian patients.
What Happens When You Skip Moisturiser
When the skin detects surface lipid depletion and water loss — as occurs when moisturiser is consistently skipped, particularly after cleansing — the sebaceous glands respond by producing more sebum to compensate. The result is often paradoxically increased oiliness. Providing appropriate hydration sends a signal that the skin’s moisture needs are met, which over time can reduce compensatory sebum production.
What Oily Indian Skin Needs
The right moisturiser for oily skin is not heavy, not occlusive, and not oil-based. It is a lightweight, water-based, gel or fluid formulation containing humectants (hyaluronic acid, glycerin) and barrier-supporting ingredients (niacinamide, ceramides in light concentrations) without pore-clogging emollients. Applied as a thin layer after actives and before sunscreen, it provides the water-phase hydration oily skin genuinely needs without adding to its sebum burden. In humid Indian summers, even a minimalist moisturiser — 2-3 drops of squalane or a light gel moisturiser — is significantly better than none.
