Moisturising / lipid-replenishing active ingredients

Common in skin care products and some injections, hyaluronic acid can raise safety questions. Is this ingredient linked to cancer risk? Answer in this article.

Hyaluronic acid has become a staple in the cosmetic industry. And for good reason: it is considered an excellent moisturising agent, which helps to give the skin a plumped and smooth texture. However, some people may be sensitive to it. So what can it be replaced with to avoid its side effects? Here are alternatives to using hyaluronic acid in skincare.

Hyaluronic acid (short: HA) is a major component of the extracellular matrix of connective, epithelial and neural tissues. This polysaccharide is known to play an important role in tissue hydration and water transport, mainly due to its enormous capacity to bind to water molecules.

For several years, hyaluronic acid has been the star of anti-wrinkle active ingredients. It is recommended for both young skin seeking hydration and mature skin, to plump up the appearance of the epidermis. However, such a popular molecule is inevitably subject to some controversies and misconceptions. Are these founded? Let's untangle the truth from the falsehood.

When applied topically, hyaluronic acid is safe and particularly well-tolerated by all skin types. It is rather in aesthetic medicine, where hyaluronic acid is used as a filler for wrinkles through injections, that redness and irritation may occur.

Hyaluronic acid is an indispensable active ingredient in cosmetics, prized for its ability to plump the skin and reduce the signs of ageing. It appears in various forms ("Sodium Hyaluronate", "Sodium Acetylated Hyaluronate", etc.), so much so that distinguishing between them can be challenging. What differences exist among these compounds? Let us take stock.

Squalane is a biomimetic active recognised for strengthening the skin barrier and preserving skin hydration. Yet its benefits can be amplified when combined with other targeted active ingredients. Which combinations are most effective? Discover intriguing associations of active ingredients with squalane.

Squalane is prized for the gentle feel it imparts to the skin and its remarkable tolerability, yet its origin often arouses curiosity. What possible origins might it have? Let us explore the various methods of producing squalane, from its extraction from shark liver to its derivation from plant-based sources.

Squalane is now present in numerous cosmetic formulations. However, even though it is often described as "biocompatible", some have raised concerns about the potential dangers posed by this active ingredient. Squalane: an ingredient to avoid? This is the question we endeavour to answer in this article.
