Product summary

Based on the ingredients included, "Peter Thomas Roth - Un-Wrinkle Night" works well for moisturizing the skin. To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. Peter Thomas Roth - Un-Wrinkle Night ticks this box. Acetyl hexapeptide-8, acetyl octapeptide-3, panthenol, arginine and glycerin 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). Palmitoyl tetrapeptide-7, isocetyl stearate, persea gratissima oil, arginine and dimethicone in this product help decrease the water evoporation from the skin, so that it stays hydrated for longer. These ingredients also soften the skin and take away the feeling of tightness and dryness.

Ingredient callouts

  • this moisturizer contains an effective form of Retinoids (vitamin A): retinol 0.40% - 0.60%. Retinoids are potent multitasking actives. They work to improve and prevent early signs of aging, reduce hyperpigmentation (age spots and post-acne marks), and prevent inflamed blemishes and clogged pores. The downside of Retinoids is that they can be irritating. If you are not already using a Retinoid in your routine, it is best to start slowly and apply the Retinoid product only a few times per week. If your skin tolerates it well, you can gradually increase the frequency to daily. Because of the irritation risk of Retinoids, we recommend to have another, retinoid-free moisturizer in your routine to use on the alternate days or when your skin feels dry.
  • This moisturizer also contains Peptides (palmitoyl tripeptide-5 0.30% - 0.50%, acetyl octapeptide-3 0.30% - 0.55%, acetyl hexapeptide-8 0.30% - 0.60%, palmitoyl dipeptide-5 diaminobutyroyl hydroxythreonine 0.25% - 0.45%, dipeptide diaminobutyroyl benzylamide diacetate 0.25% - 0.50%, palmitoyl tetrapeptide-7 0.40% - 0.65% and palmitoyl oligopeptide 0.50% - 0.70%). Peptides are a very big group of ingredients. They all consist of a different combination of aminoacids. Our skin produces Peptides naturally. Some of them work as natural antibiotics, promote wound-healing and production of collagen. The scientists are still studying how effective the topical application of Peptides is, but it is very likely that they are helpful. Peptides might be able to support skin barrier restoration and even have an anti-aging benefit. At the very least, they certainly help attract water to the skin and support the hydration in this way.
  • Panthenol (pro-vitamin B5) at about 1.50% - 1.80% concentration. In this concentration, Panthenol works effectively to improve the skin barrier and reduce inflammation.
This product contains ingredients that could be beneficial, but their concentrations are too low in this formulation: caprylic/capric triglyceride, lecithin, allantoin, butyrospermum parkii butter and vitamin e
