What the gurus are saying

That green tint is the talking point: it helps camouflage redness, and the milky, hydrating texture comes with neurosensine, a soothing peptide. Rosacea fans say it's one of the few targeted products that shows a difference, but only with patient use, morning and night. Smoothed all over, it can go streaky, chalky or ashy, so spot treating red areas over your moisturizer is the suggested move. Not everyone sees much change in redness.

"One green tinted moisturizer I really love is [...] the La Roche-Posay Rosaliac line. It contains glycerin and neurosensine, a calming peptide shown to reduce irritation in rosacea prone skin, along with the green tint. It's a very creamy moisturizer, nourishing and hydrating but not heavy and thick, and you spot treat red areas with it over your first moisturizer."

"Highly recommend checking that one out as well all right guys so hopefully you have a better understanding of peptides after this video"

"It has a wonderful hydrating texture and ingredient-wise it contains Neurosensine, a soothing peptide found in lots of their products, along with glycerin and La Roche-Posay Thermal Spring Water that is really helpful for keeping our skin microbiome healthy. It's also green tinted and green helps to offset red. If you were to use this as your moisturizer all over, I think it's too much, I've definitely done that out of curiosity and it does give this white ashy look that's not elegant."

"This also contains glycerin that's hydrating and then of course La Roche-Posay's thermal spring water that has some skin barrier soothing properties. Texture wise this is a very nice hydrating slightly more nourishing serum so I think it's great for those with more dry and sensitive skin although it doesn't feel heavy."

"I have tried the Rosaliac AR and it's kind of interesting it has a green tint to it but overall it kind of goes on streaky and chalky. It's not been my favorite."

"It does have chromium oxide green so maybe it's green-tinted which can help camouflage the redness and that's helpful, but I'm not really seeing much here unless it's just the consistency. With rosacea a lot of times the moisturizers by themselves, you spend a lot of time hunting down a moisturizer that's not going to make you miserable because a lot of moisturizers burn and sting and that can aggravate a flare of rosacea. So maybe this one is more lightweight."

"I really love it. It's a beautiful milky serum, very similar in texture to one of my other favorite ones, which is La Roche-Posay Dermalergic serum. I would put this all over, like drench my skin in it, including my eyes, neck, chest, everything in preparation for a retinol or a retinaldehyde."

"I like to pair that one with a moisturizer. [...] This will give you a little extra hydration and soothing of the skin. I do not think this one is as effective as the Avène anti-redness product but it does feel really nice and soothing on the skin, not quite as drastic of a difference in terms of redness here though in my opinion. It does have ambophenol which is a natural extract and it has neurosensing which can soothe the skin and create a great hydration barrier."

"It really is the difference in your rosacea that you just see without the flushing. But this is a product that you have to religiously use for such a long time before you see a difference and then continue to use morning and night. It can be a little pricey and sometimes it's hard to find, but I really do love this. I do feel like it's one of the only targeted rosacea products that I genuinely see a difference with. I absolutely love it."
