Erno Laszlo Firmarine Night Cream

"Erno Laszlo - Firmarine Night Cream" is a well-rounded moisturizing product. To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. Erno Laszlo - Firmarine Night Cream ticks this box. Glycerin, imperata cylindrica root extract, sodium hyaluronate, butylene glycol and caprylyl glycol 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 (glycine soja oil, ribes nigrum seed oil, butyrospermum parkii butter, helianthus annuus seed oil and squalane) 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

• We like that this moisturizer contains peptides (palmitoyl dipeptide-5 diaminobutyroyl hydroxythreonine 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 amino-acids. Some of them work as natural anti-biotics, promote wound-healing and production of collagen. The science is still not settled on how effective peptides in skincare are, 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.
