Dull or dehydrated skin

Dehydrated skin looks flat, feels tight and shows fine lines that disappear once moisture is back. The final infusion step of a HydraFacial pushes hyaluronic acid and antioxidants into freshly exfoliated skin, which is why the change is visible straight away.

What the evidence says

In a clinical study of 38 people cited by the manufacturer, skin hydration measured 338% higher 24 hours after one treatment with a hyaluronic acid booster. These are small, short-term studies, so treat them as a guide.

What clinics usually suggest

Signature or Deluxe. A Signature is usually enough. In winter, or after long flights, a Deluxe with a hydrating booster holds the result longer.

The treatment

Signature HydraFacial: The Signature is the core HydraFacial: cleanse, a gentle peel, suction extraction and a hydrating serum finish. Many Manchester clinics sell the 30-minute version as Express. In Manchester it costs from £90 to £145.
