I had hormonal acne for years.
I started Skin+Me in desperation after a very bad month and I have to say that it's made a phenomenal difference for me (not a single spot this month, even before and during my period, which used to cause terrible, large spots all over my chin). It's also helped to reduce some of the old blemishes from previous spots. Not a quick fix, though, I'm 4 months in and would say this is the first month I've really noticed a massive difference. I think simplifying my routine when I started Skin+Me helped, too. I just use La Roche Posay cleanser and sunscreen, plus moisturiser during the day and a night cream at night after the Skin+Me. A couple of times a week I use Ren rescue balm overnight to sort out any peeling or dryness from the Tretinoin in the Skin+Me.
A big thing for me has been getting the cleanser, moisturiser and sunscreen right, too. Any cleanser that's too harsh brings me out in spots (so nothing with salicyclic acid etc.), so gentle cleaners are best for me and nothing with oil in (double cleansing makes me spottier). I've tried loads of suncreams and all make me spotty, but the La Roche Posay Anthelios mattifying one works for me as it's not greasy. Their moisturiser feels too sticky for me, though, and also brings me out in spots, so I use Neal's Yard now.
I feel into a bit of a trap on here of assuming that because lots of people on here raved about a certain product it would work for me too (some suncream brands, moisturisers, cleansers etc) and then would stubbornly keep going with them even when my skin was awful. Really stripping it back to basics and testing and changing one thing at a time has been helpful for me in terms of determining what I need, what I don't need, and what is actively bad for my skin.
