Seventy Hyal

A direct, hydrating booster for dehydrated skin and quick pre-event glow.

What it is

Seventy Hyal is a hyaluronic-acid booster designed to deliver deep hydration into the dermis. Compared with Profhilo, it sits more superficially and gives a faster surface glow rather than a long bio-stimulating effect.

It is our most-recommended booster for clients in their 20s and early 30s who want better hydration without committing to a full Profhilo course.

What it treats

  • Dehydrated, lacklustre skin
  • Pre-event glow (with two weeks lead time)
  • Mild fine lines from dehydration rather than collagen loss
  • Younger skin not yet in need of bio-remodelling

How it works

  1. 1 A single 2 ml session for most clients.
  2. 2 Numbing cream applied.
  3. 3 Injections placed across the face on a standardised pattern.
  4. 4 Optional second session in 4 weeks for a stronger result.

Is this right for you?

A good fit if

  • You're in your 20s or early 30s and want a glow rather than a structural change
  • You have a specific event in 2–3 weeks and want your skin at its best
  • You want to try a single-session booster before committing to a Profhilo course

Not the right time if

  • You're pregnant or breastfeeding
  • Your concerns are about bounce or firmness rather than hydration — Profhilo is a better fit

FAQs

How is it different from Profhilo?

Seventy Hyal hydrates the surface and gives a quicker glow; Profhilo spreads more broadly and is designed as a two-session bio-remodelling protocol with a longer-lasting effect on bounce. They aren't competitors — they suit different starting points.

How quickly will I see a difference?

A subtle improvement within a week; the fuller effect by week 2.

How long does it last?

Four to six months. Top-up sessions can be spaced accordingly.
