Peter Thomas Roth Ultimate Solution 5 Multitasking Eye Cream

"Peter Thomas Roth - Ultimate Solution 5 Multitasking Eye Cream" has a good moisturizing formula. The formulation is based on a combination of good humectants and emollients. Both are needed to increase the skin hydration level. Acetyl hexapeptide-8, alanine, arginine, aspartic acid and glutamic acid 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 (ceramide np, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, jojoba esters and theobroma cacao seed butter) 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

• This product also contains Vitamin C (Ascorbic Acid). It can be an effective active for anti-aging and evening out the skin tone, but in this moisturizer it is used for stabilizing other ingredients in the formulation. In this concentration (0.20% - 0.35%) it cannot have a noticeable benefit for the skin.
• As a plus, this moisturizer also contains Ceramides (ceramide np 0.20% - 0.35%). 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 (acetyl hexapeptide-8 0.10% - 0.25%, palmitoyl tetrapeptide-7 0.15% - 0.30% and palmitoyl tripeptide-1 0.15% - 0.30%). 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.
