Mineral Oil
Mineral oil is a clear, odourless oil derived from petroleum that is widely used in UK skincare and cosmetics as an effective occlusive moisturiser. It helps lock in moisture without feeling heavy, making it a staple in creams, balms, baby oils and lip products. Highly refined cosmetic-grade mineral oil is considered safe and non-comedogenic by UK and EU regulators.
How it works in skincare
In cosmetics and skincare, mineral oil works by forming a protective barrier on the surface of the skin that reduces transepidermal water loss, thereby helping to keep skin soft and supple. Because it is inert and does not react with other ingredients, it is frequently used to improve the texture and spreadability of formulations while extending the shelf life of products. In lip care it provides a smooth, glossy finish and prevents lips from drying out.

Where it comes from
Mineral oil is a highly refined, purified distillate obtained from crude petroleum oil. After extensive processing it becomes the clear, inert liquid used in cosmetic formulations.
