Our ingredient: Phytosteryl Macadamiate

Healthy skin starts with an intact skin barrier. In our Holiko creams, we therefore use ingredients that are closely aligned with the skin’s natural structure. One of these is Phytosteryl Macadamiate.

What is Phytosteryl Macadamiate?

Phytosteryl Macadamiate is a plant-based lipid complex composed of phytosterols and fatty acids from macadamia oil. It acts as a plant-derived analogue of skin-identical cholesterol esters, which are a key component of the skin barrier.

As the skin ages, becomes dry, or when the barrier is compromised, a deficiency of these lipids can occur. Phytosteryl Macadamiate supports the skin precisely in these situations.

How does Phytosteryl Macadamiate work on the skin?

Strengthening the skin barrier

Phytosteryl Macadamiate helps to stabilise and restore the skin barrier. By mimicking the function of cholesterol esters, it supports the skin’s natural protective function.

Reducing moisture loss (TEWL)

This ingredient has a high water-binding capacity and helps reduce transepidermal water loss (TEWL). As a result, the skin retains moisture more effectively and feels nourished for longer.

Nourishing and lipid-rich

Thanks to its content of fatty acids — including palmitoleic acid — and phytosterols, Phytosteryl Macadamiate supports cell membranes and leaves the skin feeling noticeably smoother and more supple.

Soothing properties

It may help reduce irritation and redness, making it particularly suitable for sensitive or stressed skin.

Who is Phytosteryl Macadamiate especially suitable for?

Dry and dehydrated skin

Sensitive or irritated skin

Mature skin with a weakened barrier function

Skin in need of a plant-based alternative to lanolin

Why we use it in Holiko creams

We use Phytosteryl Macadamiate in Holiko creams because it is skin-affine, well tolerated, and functionally effective. It supports the skin where it is often compromised: the skin barrier and moisture balance.

Conclusion

Phytosteryl Macadamiate is not a trend ingredient, but a well-considered, skin-related building block of modern skincare. It helps maintain the skin’s natural protective function, preserve moisture, and support a more resilient-looking complexion over time.
