Musings on The Ordinary...
I've been using it solidly for a couple of years, and bloody love it. My skin looks better than it did five years ago (early 40s now).
I use a regime roughly based around this:
AM
Hyalauronic acid (ultra moisturising)
Buffet (excellent broad spectrum serum)
Alternate: Matrixyl / Argeline / Niacimide (all various anti-ageing properties)
Plus a day moisturiser from another brand (usually Beauty Pie) (I don't find TO NMF gives me enough weight or moisture).
PM
Hyalauronic acid
Buffet
Alternate: Matrixyl / Argeline / Niacimide
Alternate: Retinoid / Vitamin C / Alpha Lipoic Acid (first two are the cornerstones of anti-ageing; ALA is the most glow-giving thing in the known universe)
Plus a night moisturiser from another brand (usually Beauty Pie), or TO Squalane or Rose Oil
Leave a few moments between each layer for it to sink in.
It sounds complicated but the website does clearly explain what each one does, so you can build your own regime to your exact needs.
I like that concept, and like experimenting to build a bespoke regime for me, and add more or less of various things depending on how my skin is feeling - but it's nearly always great now.
It does take a bit more effort than most skincare brands. Only you know whether you want to put a bit of effort into it. For me, it's so cheap, I can definitely justify the effort.
TO does have a lot of detractors. The founder is beyond batshit and a complete liability on social media. There are rumours of variability in formulations, but I've never seen any proof of that. And mostly, in my opinion, people don't like it because they don't understand it.
Oh and lastly - if you are serious about skincare you do need a vitamin C - but because of the nature of the chemical formula, all vit C products feel gritty and unpleasant on the skin. Again, up to each individual whether they want to use a cream that doesn't feel great for a few moments in order to reap the benefits of the formulation on the skin.
