What oil is best for removing dark spots?
No oil removes dark spots — fading pigmentation requires slowing how much pigment the skin makes, or speeding up how fast pigmented skin cells are shed, not sealing the surface. Rosehip oil is the one most marketed for it, for its provitamin A carotenoids. Vitamin C, niacinamide, azelaic acid, and retinoids have real support, alongside daily sunscreen.

What an oil actually does to a dark spot
Oil sitting on skin slows water loss and leaves the surface looking smoother and more even, which is why a spot can look softer within seconds of applying almost any oil — that is light reflecting differently off a hydrated surface, not a change in the pigment underneath. Melanin sits inside skin cells within the epidermis, and a heavy oil sitting on the surface does not act on the cells that made it. Rosehip, argan, tamanu, castor — none of them act on the pigment-producing cells that made the spot.
The oils people actually reach for
Rosehip, vitamin E oil, argan, and tamanu are the oils sold for this. Rosehip is the one most often marketed for dark spots, on the strength of the provitamin A carotenoids it contains. Vitamin E oil is the one most associated with fading marks in popular use. Argan and tamanu are pleasant moisturizing oils with their own following. What none of the four has is a place on the list of actives dermatologists name for pigmentation, which is the comparison that matters here.
What actually has support
Vitamin C, niacinamide, azelaic acid, and retinoids are the ingredients with real support for pigmentation, and daily sunscreen belongs in any routine built around them. None of the four are oils. Castor oil has no role in fading a spot, but it remains a reasonable moisturizer to use alongside whichever of those ingredients you choose.
