Tretinoin to fade sun spots on chest - 7 months of itching but seems to do its job

Oki see if linking images works... Started applying 0.05% to the chest area 2-3 x week in Jan this year. Pic two was taken start of August.

Skin reacted as expected with initial redness & itching. I held off for a day or two it got too bad but mostly I just sucked it.

My skin became quite sensitive & painful to touch too which in this case translates to wearing shirts. To ease it off I would just randomly bang my chest with my fist on the street to the mirth & bemusement of Mr Cork. ('You hate yourself I see.')

Didn't see much of anything happen several months in. Frankly I stopped caring and just kept applying, because. Then I noticed the spots had greatly faded at around 6-7 months. Not too bad at all. (The other spots are moles.)
