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 A single 2 ml session for most clients.
- 2 Numbing cream applied.
- 3 Injections placed across the face on a standardised pattern.
- 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.
