St Moriz Professional Face Tanner Serum is a dual-purpose product designed to provide a gradual, natural-looking bronze glow while serving as a hydrating makeup primer. Formulated with hyaluronic acid, this 0.84 fl oz serum delivers lightweight moisture to support skin hydration and smoothness. The self-tanning action develops over several hours, building a subtle, dewy radiance without an orange or streaky finish. As a primer, it helps create an even base for foundation or can be worn alone for a fresh-faced, sun-kissed appearance.

The formula is suitable for daily use on the face, including combination and normal to dry skin types. Hyaluronic acid contributes to plumping and retaining moisture, which may help improve skin texture and reduce the appearance of fine lines when used consistently. The tan develops gradually, allowing users to control depth of colour by adjusting frequency of application. The serum absorbs quickly without greasiness, making it convenient for layering under makeup or wearing bare.

St Moriz positions this product as an affordable alternative to premium self-tanning and priming skincare lines. Key strengths lie in its gentle, hydrating formulation and time-saving two-in-one function. It does not contain parabens or gluten, and is suitable for vegans. The lightweight gel-like texture spreads evenly over the face and neck, minimising patchiness. For best results, exfoliate and moisturise dry areas before application, then wash hands thoroughly after use. The product can be used year-round, especially for those seeking a natural-looking glow without sun exposure or heavy makeup. As with all self-tanning products, a patch test is recommended prior to first full use to check skin compatibility.
