I promised to publish a review! I haven't used the Stress Less or Happier Barrier yet, but if they match the other products I've tried so far, I'm sure it'll be fine.
The Mighty Melt Balm: works very well, no stinging, no scent, no stripping feeling! I usually don't feel the need to double cleanse - but I don't wear that much makeup, so you might want to double cleanse if you do. Skin feels very soft after use.
Calm Down: seems to be a very gentle exfoliator. No problems so far.
A-Game 5 retinal: I was a bit scared, because I've tried retinol before and had a bad reaction. But this is a very low dose (0.05%) and my skin is not protesting! I'm currently using it twice a week. It's too early to speak of results, but I will continue to use it and if it goes well, I can switch to A-Game 10 in time.
My skin already was in pretty good shape, but it does seem to look a bit extra clean and bright.
Very happy with this brand so far - I might check out their vitamin C serum, although the keeping it in the fridge / decanter situation seems like a hassle.
If you were debating whether to try this brand, I'd say give it a go!
