Product Summary

"Peter Thomas Roth - Day and Night Moisture Must-Have Duo" is a well-rounded moisturizing product. The formulation is based on a combination of good humectants and emollients. Both are needed to increase the skin hydration level. Acetyl hexapeptide-8, acetyl octapeptide-3, dextran, glycerin and mannitol in this product (humectants) attract water molecules to the upper layer of the skin (the water comes from the outside air or from the deeper layers of the skin if the air is dry). Emollients in this formulation (caprooyl phytosphingosine, ceramide eop, ceramide np, ceramide ns and palmitoyl tetrapeptide-7) help to reduce the moisture loss from the skin. They also soften the skin surface and relieve the feeling of dryness and tightness.

Ingredient callouts

  • As a plus, this moisturizer also contains Ceramides (caprooyl sphingosine 0.30% - 0.75%, caprooyl phytosphingosine 0.35% - 0.85%, ceramide ns 0.45% - 1.10%, ceramide np 0.50% - 1.10%, ceramide ap 0.45% - 1.10%, ceramide eos 0.50% - 1.15% and ceramide eop 0.55% - 1.30%). Ceramides are a type of lipids that our skin produces itself. They are a building block of the skin's barrier. Ceramides used in skincare are synthetic or extracted from plants. They work well for softening the skin surface and "patch holes" in the skin's barrier.
  • We like that this moisturizer contains peptides (palmitoyl tripeptide-1 0.35% - 0.85%, palmitoyl oligopeptide 0.35% - 0.85%, tripeptide-1 0.35% - 0.80%, trifluoroacetyl tripeptide-2 0.30% - 0.75%, palmitoyl hexapeptide-19 0.30% - 0.75%, acetyl octapeptide-3 0.30% - 0.75%, acetyl tetrapeptide-2 0.30% - 0.75%, palmitoyl tetrapeptide-7 0.35% - 0.85%, acetyl tetrapeptide-9 0.30% - 0.75%, palmitoyl hexapeptide-12 0.35% - 0.80%, acetyl hexapeptide-8 0.30% - 0.75%, acetyl tetrapeptide-11 0.30% - 0.75%, acetyl hexapeptide-1 0.30% - 0.75%, tripeptide-10 citrulline 0.30% - 0.75%, palmitoyl tripeptide-5 0.30% - 0.75%, dipeptide diaminobutyroyl benzylamide diacetate 0.30% - 0.75% and hexapeptide-11 0.30% - 0.75%). There are many different kind of Peptides and they are naturally present in our skin. They all are a combination of aminoacids. Some of them work as natural antibiotics, promote wound-healing and production of collagen. The science is still not settled on how effective Peptides are in skincare, but it is very likely that they have a benefit. Peptides might help restore the skin barrier and fight the signs of aging. At the very least, Peptides work as humectants: they attract water to the upper layer of the skin and improve its hydration.
