I’ve tried 2 eye patches by Koelf so far, and they have a strong perfumed scent and the sort of sharp tingling feeling that one mostly gets from using something too minty (appears after several minutes). The rose ones caused tiny bumps on my skin if I used them too often but did have a very strong whitening effect on my skin. I mostly use them for my upper cheekbones where most of the sun damage is. It works for me but I would advise sensitive or breached barrier skin types to stay clear, this is not a gentle product. Will take a pick once I get them.
