La Prairie Anti-Aging Hydra Tint SPF20
There are over 70 ingredients in Anti-Aging Hydra Tint SPF 20 and about half of them have any appeal whatsoever. To be fair, some of them are very appealing. But the potential benefits seem to be cancelled out by something else. Take horsetail, which is full of antioxidant quercetin. This also a natural source of silica, but that hasn’t stopped La Prairie dominating this tinted moisturizer with chemical silicones.
Phytosterols have been shown to repair the skin barrier, the uppermost thin layer (although the study specifically refers to soy phytosterols and we aren’t told the provenance of the ones here. But perhaps not trusting its customers to be patient enough to wait for its effects, La Prairie has outweighed it with polymethyl methacrylate, a plastic used to make plexiglass and a filler typically used in foundation to camouflage the appearance of wrinkles.
Buried in the midst of Anti-Aging Hydra Tint is a most intriguing ingredient that I haven’t come across before: ilomastat. It turns out to be is a potent inhibitor of collagenases, destructive enzymes that break the peptide bonds in collagen. Specifically, it seems to keep matrix metalloproteinases (MMPs) in check. This is a very good thing because MMPs lurk about waiting for the skin matrix to get worn out or damaged then they start chopping it up. Bring on ilomastat, say I. Anyway, I am grateful to La Prairie for, if nothing else, putting this on my radar and I shall look into it for a longer post.
Perhaps ilonostat is here to counteract the effects of potassium thiocyanate, which can damage the skin and cause eczema, or propylene glycol, which should not be used on damaged skin. Not to mention linalool, a possible carcinogen, or the irritant butylphenyl methylpropional.
Still I shouldn’t harp on the negative as there are the peptides palmitoyl tripeptide-8 and caproyl tetrapeptide 3, the anti-inflammatory ursolic acid and carnosine. But however I look at this, the multitasking done by La Prairie’s Anti-Aging Hydra Tint is to balance the good with the bad.
