I use both. I really like the LRP Toleriane Dermo Cleanser, my DD likes the Sensitive Micellar water and the eye contour cream sorted out some really dry, red skin she had under her eyes. I also like the Toleriane Ultra moisturiser. They are more expensive but, since they're usually in 200ml bottles rather than the 30ml Ordinary sizes, they work out as good value too.
The Ordinary- using the Hyaluronic Acid for hydration, Caffeine, Buffet and the gentle 20% Vit C in Vit F oil based serum.
However, something gave me a reaction - I don't think from skincare products, probably food - and my eyelids went super dry, my lips swelled up and peeled, horrifically dry. So, apart from antihistamines, I've been using the HA and LRP moisturiser for the last week.
I think both ranges are good, no parabens, perfume etc which I like. You have to research the Ordinary and I've seen many people go mad and buys stuff which they don't understand and then misuse or overuse, especially the acids.
Sorry for long post, I'd recommend both as long as you know what you're doing with TO products.
