Hydrating Oil

A hydrating oil is one plant oil, or a blend of several, that you press onto the skin as the last step. It works differently from a cream. An oil does not add water to your skin, it keeps water from leaving. That is why an oil on its own can still leave dehydrated skin feeling tight. Layered over a water-based product, it does its job properly. You will find face and body options here, as part of our wider Skin care selection.

Fatty acids decide how an oil feels

The fatty acid profile matters more than the price on the bottle. Oils high in oleic acid, such as argan, avocado, marula and sweet almond, feel richer and stay on the skin longer. Dry and mature skin usually prefers these. Oils high in linoleic acid, such as rosehip, grapeseed and hemp seed, feel lighter and sink in faster, which suits oily and combination skin better. Squalane is a dry oil: very thin, absorbs almost instantly, and is among the least likely to block pores. Jojoba sits close to the skin's own sebum, so it is a sensible first oil if you do not yet know how your skin reacts.

Light and packaging affect quality

Oils rich in linoleic acid oxidise faster, which means they turn rancid sooner and start to smell sharp. Dark glass, a cool cupboard and a smaller bottle you actually finish are therefore practical, not decorative. A pipette draws in fresh air with every use, so a pump is often the steadier option. Many facial oils carry a period after opening of around six months.

How we choose the oils we stock

We look at three things before an oil enters our range: the oil itself, how much of it is in the formula, and whether the blend makes sense. We favour cold-pressed oils in dark glass, because delicate oils lose quality in light. We keep single oils like jojoba and squalane alongside blends, so you can test one thing at a time instead of guessing between ten ingredients. We are careful with heavily perfumed oils marketed for sensitive skin, since that combination rarely helps. Every product passes our compliance team, we test products ourselves, and independent labs spot-check batches. Read how we select brands and products.

Who benefits most, and what an oil will not do

An oil earns its place if your skin feels rough, flaky or tight by the afternoon, if central heating or wind dries you out, or if your cream alone stops feeling like enough in winter. It also works well as a body oil after showering, on damp skin, where it holds moisture in better than on dry skin.

What an oil cannot do is replace hydration. If your skin is dehydrated rather than dry, start with a water-based serum and finish with the oil on top. Humectants, ingredients that pull water towards the skin, do the drawing in, and the oil keeps it there. That is why many people combine an oil with products containing hyaluronic acid instead of choosing between them.

Comfort is usually noticeable the same evening. Changes in texture and evenness need patience: expect to judge that after two to three weeks of consistent use, and give a new oil a small patch test on the jawline first if your skin reacts easily.
