I Have been prescribed the above and I find it hard to use the 0.05% Tret everyday - I use it more like every 2 or 3 days as that's what I tolerate best. It is prescribed for melasma which is all over my face. Not in just a patch. I'm worried that I'm not getting enough HQ using it every 2/3 days and it'll take forever to get anywhere with this. Am I overthinking it or should the Tret and the Hq be prescribed separately so I could the Hq more? Hope someone can come along and advise! Thanks
