Hydrolyzed Crithmum Maritimum

Hydrolyzed Crithmum Maritimum is derived from sea fennel, a succulent plant that grows in coastal regions. The hydrolyzed form—meaning the plant material has been broken down into smaller molecular components—is used in skincare as a humectant and skin conditioning agent.This ingredient works by drawing water into the skin and helping it remain there, which contributes to improved hydration and a smoother skin surface. It also contains amino acids and polysaccharides that support the skin's natural moisturising factors.

As a humectant, hydrolyzed Crithmum Maritimum draws water molecules into the outer layers of the skin. This increases hydration levels and plumps the skin temporarily, which can help fine lines and dry skin appear less pronounced.The ingredient also contains amino acids and carbohydrates that mimic components of the skin's own natural moisturising factor (NMF). This allows it to condition the skin and support its ability to maintain hydration over time, rather than just providing surface-level moisture.

Hydrolyzed Crithmum Maritimum is typically found in serums, essences, and moisturisers. For best results, apply it to damp skin to maximise the hydrating effect—the humectant will help seal in moisture from a toner or hydrating essence. It can be used daily as part of your morning and evening routine, and works well in combination with heavier creams or oils that lock hydration in place.

Generally well-tolerated and suitable for most skin types, including sensitive skin. No significant safety concerns are documented, though patch testing is always recommended for those with known sensitivities to marine or plant extracts.
