Vitamin D is a cornerstone of skin health, but with sunlight being our primary natural source, it's crucial to exercise caution against overexposure to potent rays.

To combat this, Esse Skincare's new Pro-Sun D serum, containing Provitamin D, has been formulated to harness UV rays to enhance vitamin D levels in the skin and reduce time spent in the sun.

Proposed benefits include repairing the barrier function, resulting in plumper and more hydrated skin. Esse says it also regulates cell regeneration for a healthy glow and calm inflammation, which slows the ageing process.

Company founder Trevor Steyn says: “By boosting the levels of the starting material for this critical vitamin, we can help people make the most of their sun exposure."

This serum is suitable for all skin types and is touted as more effective than pill forms of vitamin D.
