A composition to treat epidermal insults comprises suspended nanodiamonds. The nanodiamonds may be unagglomerated and ungraphenated detonation synthesis nanodiamonds at 2 nm to 4 nm in initial crystal size and 0.2%-0.5% composition weight. The nanodiamonds may be suspended homogeneously in medical grade Sea Buckthorn berry oil. The nanodiamonds may be suspended in group consisting of Sea Buckthorn berry oil, Sea Buckthorn seed oil, glycerin, olive oil, Dimethyl sulfoxide (DMSO), hand creams such as those sold under the tradename UDDERLY SMOOTH and WORKING HANDS (e.g., Udderly Smooth, Working Hands), hydrocortisone cream, triple antibiotic ointment, and combinations thereof. The nanodiamonds can be agglomerated crystals 30 nm to 50 nm in diameter.
