“Biotherm’s Blue Therapy Red Algae Uplift Day Cream is a velvety formula designed to target the visible signs of ageing.”
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains adenosine.
These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: palmitoyl tetrapeptide-7, palmitoyl tripeptide-1.
Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.

“Infused with 100% natural life plankton, the cream works to soften the appearance of fine lines and wrinkles.”
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:
glycerin, sodium lactate.
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: dimethicone, cetearyl alcohol.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: palmitoyl tetrapeptide-7, palmitoyl tripeptide-1

Product summary
Judging from the ingredient list, "BIOTHERM - Blue Therapy Red Algae Cream" works well for improving skin hydration The formulation is based on a combination of good humectants and emollients. Both are needed to increase the skin hydration level. Glycerin, sodium lactate, rhamnose, 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 (palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, dimethicone, cetearyl alcohol and cetyl 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
- This moistruizer also contains peptides (palmitoyl tripeptide-1 0.30% - 0.55% and palmitoyl tetrapeptide-7 0.30% - 0.55%). Peptides is a very big group of ingredients. They all consist of a different combination of amino-acids. Our skin produces peptides naturally. Some of them work as natural anti-biotics, 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 peptides in skincare are helpful. They 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.
- Adenosine 0.25% - 0.45% in this product adds an anti-aging property to it. Adenosine is a chemical present inside our skin cells. A clinical trial confirmed that topical application of adenosine in a low concentration reduce dynamic wrinkles (these are the wrinkles that appear with age in a places where we our mimic is the most active, for example, in the corners of the eyes or on the forehead).
Irritation risk
