I just began using hydroquinone 4% and Retin A 1% 2 weeks ago for mod- severe malasma . I am 42 and have battled this for 20 years.. The patches now cover my entire cheek area down to chin and i have smaller patches on my forehead. I apply obagi sunscreen spf 30 or 50 twice a day wear hats most of the time.
The problem is that I spend 1.5 hours in a pool 2-3 days a week swimming so I can not wear a hat. I do lather on sunscreen.

1.Can I expect to see results or will my malasma get worse with this sun exposure while on medication?
2.Am I a poor candidate for treatment because of my sun exposure?
