I saw my dermatologist today. Apparently there is enough damage to the underlying layers of skin that he feels I will have a spot on my face where the skin pigment is damaged and will result in a lighter color.
Also, he was adamant that I stay out of the sun, which will cause further pigment damage and do not expose the area to cold/freezing conditions..
Good advice. Refreezing will make the damage far worse.
As much as I hate to suggest it, your winter may be over.

The treatment for frostnip is to cleanse the area with q-tips dipped in hydrogen peroxide. Pat or air dry and apply a thin layer of ointment such as polysporin, bacitracin or aquaphor. Try to keep any blisters that develop intact. Wounds should heal in 3-4 weeks.
A comment on terminology--your description fits what Washburn calls superficial frostbite: "involves only the skin or the tissue immediately beneath it". Frost-nip is very surface only, can be treated with immediate rewarming, and has no lasting effects or effects lasting at most a few days (similar to a non-severe sunburn). The blisters indicate you have some tissue damage. (Washburn distinguishes three degrees: frost-nip, superficial frostbite, and deep frostbite.)
Ref: Washburn, Bradford, "Frostbite, What it is--How to Prevent it--Emergency Treatment", Museum of Science, Boston, 1975. (Versions were also published in The American Alpine Journal, June 1962 and The New England Journal of Medicine, 266:974-989 (May 10, 1962).
Dr. Murray Hamlet (formerly of the U.S. Army's Research Institute of Environmental Medicine, Natick, MA) gives lectures on frostbite and other cold injuries to outdoors groups (AMC, MIT Outing Club, and others). (The lectures are fantastic--I recommend them highly.) IIRC he suggested that we call him if we had a problem and he could refer us to local experts. You might be able to call the Army Research Institute in Natick and get a local reference.
Good luck and good healing,
