Grape seed oil is a by-product of winemaking, pressed from the seeds left after the fruit is crushed. It is the lightest carrier oil in common use — it sinks in almost immediately and leaves no film, which makes it the choice for anyone who dislikes the greasy feel of coconut or olive oil.
It is mildly astringent, meaning it tightens and cleans the skin surface rather than just coating it. On feet that translates to a useful role against the bacterial and fungal infections that take hold in damp skin, and it deals well with the general grime that collects on a foot over a day.
For anyone with oily skin, or anyone who needs to put socks and shoes straight back on, this is the practical carrier.
