Turmeric is known to come from the ginger family, and it has been used in traditional medicine to heal wounds, cuts, and burns in general.  It has been used in a number of face packs as well as in skincare items in general in more recent years, and it has of course been used in homemade facials to some degree.  It can be combined with various other ingredients, and if done right, it could potentially revitalize the skin while protecting from further infection and as traditionally used, it could help to heal the skin at a higher rate, which equals out to the skin regenerating itself essentially speaking and overturning dead skin cells while also preventing scarring or other problems that so commonly happen to the skin. 

This can be best combined with things like lemon, aloe vera, and green tea among others.  But it depends on the targeted types of results that you want to get as to what you actually end up combining turmeric with to get the greater results you are looking for in skincare and otherwise.  Internally of course, it can have varying other benefits, depending on what you are again combining it with, and it would be advisable to consider all of these benefits in that range.
