hope she's being vigilant with her diet, shellfish and fungi are foods that usually cause the flare up
i recommend Dr. Vincent Ho from the skin care centre. very down to earth honest guy, not there to bullshit you or try to sell you expensive regimes or treatments. he'll tell you what works and what does not
Dr. Phoebus Wong is another one that comes to mind, but he charges a consultation fee - last i heard it was around $40 bucks even for a 5 min convo, dunno if the rates have gone up
Dr. Lorne Brown is a cosmetic surgeon but also treats skin ailments
afaik, he charges a $100 consultation fee but that goes toward your bills should you seek treatment from his clinic. you can email/call them to find out if they treat eczema
i've had my fair share of skin ailments and still suffer from it so hope all goes well for your gf, good luck
