Most serums work on the surface. This one starts underneath it. TriHex+ clears out damaged collagen and elastin first, so the skin has room to lay down new protein rather than building on top of old, and Octapeptide-45 is the addition that makes it TriHex+ rather than the original blend.
Alastin Restorative Skin Complex is a peptide serum built on TriHex+ with Octapeptide-45, formulated to support the skin's own production of collagen, elastin and hyaluronic acid. It carries Magnolol for facial volume, which few serums address. It targets loss of volume, fine lines, texture and dullness on the face, morning and evening.
The name worth knowing is Magnolol. Alastin includes it to support the body's natural production of healthy facial fat, the layer under the skin that thins with age and takes volume with it. Very few serums address that layer at all, and it is the reason this sits at the top of the range on price.
Niacinamide sits third in the ingredient list, after water and glycerin. Alastin describes it as an antioxidant that works on visible pigmentary concerns, which is where the tone and dullness claims come from. Under the headline actives sit ceramides AP and NP, ergothioneine, squalane and phospholipids, which are why the texture behaves like a light lotion rather than a thin serum.

In Alastin's own 12-week study, 98% agreed it improved skin hydration, 89% reported improvement in overall skin texture, and 93% reported overall satisfaction. Alastin publishes no participant count alongside those figures.
Skin that has started to lose volume and firmness rather than skin with one surface concern. If the face looks flatter or more tired than it used to, this is the product in the range built for it. It is the step up from Regenerating Skin Nectar, and the two are the pair most people build an Alastin Skincare routine around.
