Product summary

"Sulwhasoo - Ultimate S Cream" has a good moisturizing formula. To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. Sulwhasoo - Ultimate S Cream ticks this box. Acetyl hexapeptide-8, acetyl octapeptide-3, glycerin, polyglycerin-3 and honey 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 (phytosphingosine, dimethicone, helianthus annuus seed oil, squalane and cetearyl alcohol) 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

  • Another benefit is that this moisturizer contain ceramides (phytosphingosine 0.30% - 0.55%). Ceramides are an important part of our natural skin barrier. The Ceramides used in skincare are synthetic or come from plants. They help soften the skin and can help "fill the gaps" in the skin barrier, keeping the skin hydrated and resilient for longer.
  • We like that this moisturizer contains peptides (acetyl octapeptide-3 0.10% - 0.20% and acetyl hexapeptide-8 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.
This product contains ingredients that could be beneficial, but their concentrations are too low in this formulation: vitamin e and butyrospermum parkii butter
