Pair this with your SHIELD day cream with seaweed and SPF15. These bundles and products are trusted by thousands to take results to the next level.
You only need a tiny amount, it provides great coverage, easy to apply and non offensive smell. Will keep buying. I only wish it was higher than spf15 and also, not a tub format where you expose the product every time you take the lid off.
Fantastic product . The team have very prompt follow up to any queries .
Bery glad i found Phyco health
Lovely ,thank you
Beautiful moisturiser.
I like this product but don't love it. What I do love is it has literally no fragrance and this is important for me as I am very sensitive to scents. I like that it dries quickly but too quickly so is difficult to spread. With combination menopause skin that has flaky areas, the white zinc in this product shows up in these areas. I do LOVE my other skincare products from Phycohealth which I have been using for about 3 weeks and am noticing continued improvements I.e, my flaky areas are decreasing.
Hi Tanya,
Shield is actually designed as a protective layer—a sunscreen and pollution shield—rather than a typical moisturiser. Its formula, based on natural mineral zinc (not chemical filters), can feel a bit different on the skin. It works best when applied sparingly: just a small amount is enough, and it should absorb nicely after a couple of minutes.
Here’s our recommended method for using Shield to get the best results:
Start with a clean face (using our Cleanse, if you have it, is great for gently removing pollutants).
Apply Soothe for a layer of lightweight, skin-plumping moisture.
If you have drier areas, add Nourish or another moisturiser to those spots.
Finally, apply a thin layer of Shield. Rub a small amount between your hands to spread it out, then gently press your palms across your face, neck, and any areas exposed to the sun.
If you’re looking for a more traditional moisturiser, Nourish might be a better fit—it’s rich, hydrating, and blends in smoothly.
Thank you for trying our products, and please reach out with any other questions!
