1 If your bruise is causing pain, take an over-the-counter pain medicine, such as acetaminophen (Tylenol), ibuprofen (Advil, Motrin), or naproxen (Aleve). Read and follow all instructions on the label. 2  If desired, apply a natural product directly to the bruise.  Witch hazel may help heal damaged veins.
Also a big fan of linoleic oils! I have dry, dehydrated and acne-prone skin. From my own experience, it seems that linoleic oils such as hemp seed, rosehip (especially), passionfruit, and evening primose have helped my skin out the most when it comes to evening out the tone and diminishing active acne and scarring.
Lemon essential oil contains vitamin C and is also good for acne scarring. It has antibacterial properties and also prevents the formation of new acne on the skin. Find more uses for this oil in my article about 10 amazing uses for lemon essential oil.
