“Regenerative Anti-Ageing Moisturiser”
This product can help improve hydration of the skin with the two types of ingredients.
The first type is called “humectants”:
these ingredients help attract water.
When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from
within deeper layers of the skin. The following ingredients in this product do the job:
glucosamine hcl, glycerin.
This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: butyrospermum parkii butter, caprylic/capric triglyceride.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: tetrapeptide-21
“Regenerative Anti-Ageing Moisturiser”
This product contains tetrapeptide-21. This ingredient might be able to help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness, but there is not enough evidence that it actually works.
The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually works: glucosamine hcl.

At the same time, this vitamin C derivative has been shown in studies to be effective in reducing acne, blemishes and clogged pores. It is less irritating then the pure form of vitamin C

Judging from the ingredient list, "Algenist - Regenerative Anti-Ageing Moisturiser" works well for improving skin hydration To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. Algenist - Regenerative Anti-Ageing Moisturiser ticks this box.

Limnanthes alba seed oil, butyrospermum parkii butter, caprylic/capric triglyceride, dimethicone and cetyl alcohol in this product help decrease the water evoporation from the skin, so that it stays hydrated for longer.
