Is seabuckthorn good for your skin? can it heals acne?

Sea buckthorn: Sea buckthorn berries or seed oil can be used topically on the skin for sunscreen; for treating radiation damage from x-rays and sunburns; healing wounds like bedsores, burns, and cuts; for acne, dermatitis, dry skin, eczema, skin ulcers, postpartum pigmentation, etc. It contains fruit acids, flavonoids, carotenoids, and fatty oils. I could find no actual research data for acne, though.
