Does the Oil Under Concealer Hack from TikTok Really Work?

Beauty trends on TikTok rarely receive sustained professional scrutiny. One that has steadily gained traction is the “oil under concealer” hack, the idea that applying a facial oil beneath your concealer creates a smoother, crease-free finish. The question is whether it actually delivers.

The method is straightforward. Instead of prepping the under-eye area with eye cream or primer, you press a small amount of facial oil into the skin and then apply concealer on top. Videos promise fewer visible fine lines and better blending.

Publications such as Vogue Arabia and Allure have examined the trend, speaking to makeup artists and dermatologists to separate technique from hype. Experts describe the results as conditional rather than universal. Hydration does improve how concealer sits on the skin. If the under-eye area is dry, product is more likely to catch, crease or look textured. A lightweight oil can soften that surface, allowing concealer to spread more evenly.

Professionals also stress moderation. Too much oil can break down the concealer, causing it to slide or separate, particularly in warm climates. In hot, humid conditions, this matters. Oil changes the way makeup adheres. In small amounts it can add flexibility; in excess it can interfere with longevity.

Skin type remains a deciding factor. Dry or mature skin may benefit from a thin layer of a fast-absorbing oil pressed in before concealer is applied. Oily or combination skin is more likely to experience shifting and excess shine. Formula pairing also plays a role. Creamy, hydrating concealers tend to perform better over oil than matte, high-coverage formulas.

The hack is not revolutionary. It is an alternative to proper skin preparation. A well-formulated eye cream can offer similar slip without the risk of destabilising makeup. The real principle is balance: hydrated skin supports smoother application, but excess emollience compromises wear time.

So does it work? In specific circumstances, yes. It is not a universal fix. The outcome depends on your skin, your climate and the products you use. Like most viral trends, it is less about a shortcut and more about understanding how makeup behaves on your own skin.
