The Revitalizing Hydrating Serum De La Mer, Analysis And Alternative

This lightweight serum floods skin with gentle hydration, revitalizing it with marine-derived energy so your skin looks more radiant, healthy and fresh.

A torrent of Miraculous Broth – the healing force that flows through all of La Mer’s products – softens, nourishes, soothes and gives skin the energy it needs to focus on repairing.

This Miraculous Broth is in the heart of La Mer and is present in all the treatments in the collection. The elixir is formulated with hand-harvested seaweed and other nutrients and minerals unlocked through a natural fermentation process.

Supports the five facets of natural healing: hydration, regeneration, smoothness, calm and radiance, which help restore skin to its healthiest state.

The formula combines this proprietary ingredient with Lime Tea Concentrate, a powerful antioxidant that provides a vital defense against external influences that can visibly deplete the complexion.

While the tiny micro-droplets of Deep Hydration Ferment penetrate quickly to bring dry and dehydrated skin back to life.

La Mer serum has a quantity of 30 ml, and its price exceeds € 150. Is it worth this outlay to treat our skin? This is what we are going to check by analyzing its ingredients.

Analysis The Revitalizing Hydrating Serum de La Mer

Summary analysis The Revitalizing Hydrating Serum de La Mer

La Mer’s “miracle broth” formula – the secret ingredient in Crème De La Mer – is as well-guarded as the recipe for Coca-Cola.

However, if the ingredients are studied individually, the miracle broth turns out to be a very unimpressive mix of algae and minerals, which does not justify its high price at all.

The dominant ingredient is water, but it is not just H2O. La Mer uses unstructured water, which is simply that the molecules have been separated so that they are more easily absorbed by the body – although there is no scientific evidence that this is the case.

But at first glance, it seems that there is much more than just designer water inside the revitalizing and hydrating serum.

It has far fewer fillers than most beauty products, and with a glance at INCI you quickly realize that it has an impressive array of botanicals.

La Mer has focused on marine botanicals, but research on these assets is often sparse. There is a good amount of algae, whose function is almost always the same: antioxidant and hydrating.

Although most of the properties of algae are given by the manufacturer, and it is impossible to contrast it with another source. A study (one of the few) on Asparagopsis Armata (a species of red algae) showed that it was cytotoxic.

The most convincing is Ascophyllum Nodosum extract, which has been shown to be an antioxidant with free radical absorption capacity.

There are a surprising number of ingredients that could be the cosmetic equivalent of wolves in sheep’s clothing. One of them is Nordihydroguaiaretic Acid, which was banned for consumption because it was found to be toxic, although it may have the benefit of clearing acne.

Along the list are a couple of interesting ingredients. One is Ethylbisiminomethylguaiacol Manganese Chloride, a useful antioxidant that prevents damage caused by UVB rays. And the other is Argireline, a peptide that prevents and treats the formation of wrinkles.

Although I must admit that La Mer serum is an anti-aging product full of interesting assets, there are really too many ingredients for the really beneficial ones to exert their effect properly.

With so little solid evidence behind some of these assets, I don’t think the broth is as miraculous as it is painted. For the cost, I would like to have a more concentrated formulation, with what matters at the top of the list.


This product is not suitable for all pockets, we understand that. That is why we give you a more affordable and equally -or even more- effective recommendation for treating mature skin.

And this alternative is the Nezeni Cosmetics Intensive Antiage Serum, full of beneficial ingredients to treat aging, such as Vitamin C, Cobiolift or Hyaluronic Acid.
