Question 1

What is Seventy Hyal 2000 and how is it different from dermal filler?

Accepted Answer

Seventy Hyal 2000 is an injectable skin booster, not a dermal filler. This distinction matters clinically and understanding it changes what you should expect from the treatment.

Seventy Hyal 2000 works by delivering high molecular weight hyaluronic acid deep into the dermis, where it acts as a hydration reservoir while simultaneously stimulating the fibroblasts responsible for producing collagen and elastin.
It does not fill. It replenishes and biostimulates. The result is improved skin quality, hydration, and resilience rather than any change in facial structure or volume.

Question 2

How does Seventy Hyal 2000 work at a biological level?

Accepted Answer

Seventy Hyal 2000 contains high molecular weight hyaluronic acid, which is the form of HA most similar to what is naturally present in healthy, well-hydrated young skin. As we age, the concentration and quality of dermal hyaluronic acid declines, contributing to the loss of plumpness, resilience, and radiance that characterises skin ageing.

When injected into the dermis, Seventy Hyal 2000 does two distinct things simultaneously.

The hydration effect is not superficial. Hyaluronic acid in the dermis attracts and holds water molecules, improving the tissue's intrinsic capacity to stay hydrated rather than simply adding moisture at the surface.

The fibroblast stimulation means the results develop and improve over weeks following treatment as new collagen integrates into the dermal architecture, producing improvements that look earned rather than applied.

Question 3

What concerns does Seventy Hyal 2000 treat?

Accepted Answer

Seventy Hyal 2000 is most effective for concerns driven by declining skin hydration, reduced dermal thickness, and early to moderate changes in skin quality and texture.

It is particularly effective for perimenopausal and menopausal patients, where oestrogen withdrawal drives a significant decline in dermal hyaluronic acid alongside the collagen loss that defines this stage of skin ageing.

Replacing the dermal HA that oestrogen was previously maintaining, while simultaneously stimulating new collagen production, addresses both drivers of the skin change rather than one in isolation.

Question 4

How many sessions do I need and how far apart?

Accepted Answer

The standard initial protocol for Seventy Hyal 2000 is three sessions, spaced two to four weeks apart. This schedule reflects the biology of the treatment and allows each session to build on the cellular activity initiated by the one before it.

Three sessions is the recommended initial course for most patients. Patients with more advanced dehydration or more significant early laxity sometimes benefit from a fourth session before moving to maintenance.

Maintenance is not optional if you want to sustain the results. The dermal hydration reservoir that Seventy Hyal 2000 establishes does not remain indefinitely without periodic replenishment.

Question 5

When will I see results and what will they look like?

Accepted Answer

Some patients notice an improvement in skin radiance and hydration within days of the first session. This early response reflects the immediate hydration effect of the high molecular weight HA.

The deeper, more structural improvements, those driven by collagen and elastin stimulation, develop more gradually.

Most patients describe their skin looking more alive and more hydrated.

Not dramatically different. Genuinely healthier. People around them comment that they look well or ask what they have changed in their skincare routine. This is the result we are aiming for: an improvement that looks intrinsic rather than applied.

Question 6

How long do results last?

Accepted Answer

Results from a full course of Seventy Hyal 2000 typically last four to six months before maintenance is recommended.
Several factors influence how long the results hold for any individual patient.

Patients who maintain Seventy Hyal 2000 consistently over time develop progressively better baseline skin hydration and quality.

The cumulative effect is one of the strongest arguments for treating it as a long-term skin health investment rather than a one-off course. Each maintenance session is building on a foundation that the previous ones established.

Question 7

Is Seventy Hyal 2000 suitable for all skin types and ages?

Accepted Answer

Seventy Hyal 2000 has an excellent safety profile across all skin types and Fitzpatrick classifications. Because it contains no cross-linking agents and works through deep hydration and biostimulation rather than any ablative or thermal mechanism, it carries no risk of post-inflammatory hyperpigmentation, making it well-suited to patients with darker skin tones.

There is no upper age limit. The dermis always responds to the right biological stimulus, and the hydration and fibroblast activation that Seventy Hyal 2000 provides are relevant at every stage of skin ageing.

The youngest patients tend to use it preventatively. Older patients use it as part of a broader regenerative protocol that may also include polynucleotides, Profhilo, or other treatments depending on their specific concerns.

Question 8

Can Seventy Hyal 2000 be used on areas other than the face?

Accepted Answer

Yes, and extending treatment beyond the face is something I actively discuss with patients whose concern includes the areas most likely to reveal skin age alongside the face.

The neck and decolletage are the areas I most commonly treat alongside the face, because the skin in these areas ages in direct parallel with facial skin but is frequently excluded from treatment plans.
Patients who invest in their facial skin while leaving the neck and decolletage untreated often find the contrast becomes more apparent as treatment progresses. Treating all three areas together produces a more coherent and natural overall result.

Question 9

How does Seventy Hyal 2000 compare to Profhilo?

Accepted Answer

Both are injectable hyaluronic acid skin boosters designed to improve skin quality from within. The differences lie in the concentration of HA, the technology, the mechanism, and what each is best suited to achieve.

Seventy Hyal 2000 excels at deep dermal hydration and is particularly effective for patients whose primary concern is dehydration, dullness, and the loss of skin plumpness associated with HA decline.
Profhilo's NAHYCO technology and higher total HA concentration produce a broader bio-remodelling effect that addresses laxity and overall skin quality more comprehensively.

For some patients one treatment is the clear choice. For others, combining both, with Seventy Hyal 2000 establishing the dermal hydration foundation and Profhilo layering on a broader bio-remodelling effect, produces results that neither achieves alone.

Question 10

Can Seventy Hyal 2000 be combined with other treatments?

Accepted Answer

Yes, and thoughtful combination with other treatments at Juvenology consistently produces better outcomes than using any single treatment in isolation.

The general principle at Juvenology is to optimise the tissue environment first, establishing deep hydration and cellular health, before addressing structural or volume concerns.

Seventy Hyal 2000 is often the starting point of that process, building the dermal foundation on which every other treatment works more effectively. A well-hydrated dermis with active fibroblasts responds better to every regenerative stimulus it subsequently receives.
