FAQs
Q1. What is Trifluoroacetyl Tripeptide-2 in Hydrinity Renewing HA Serum?
A1. Trifluoroacetyl Tripeptide-2 (trade name Thymulenol) is a signal peptide that specifically targets the progerin pathway in skin aging. Progerin is a mutant form of lamin A — a structural protein in the cell nucleus — that accumulates in aging skin cells, causing them to senesce (become dysfunctional and stop regenerating) prematurely. Thymulenol has been shown in clinical studies to inhibit progerin expression and reduce the nuclear deformations it causes, effectively delaying one of the fundamental molecular mechanisms of cellular aging. This makes it a meaningfully different anti-ageing active compared to conventional peptides that primarily stimulate collagen — it operates at the nuclear level of cell senescence rather than only at the extracellular matrix level.
Q2. What is Nicotiana Benthamiana Hexapeptide-40 in the Renewing HA Serum?
A2. Nicotiana Benthamiana Hexapeptide-40 Sh-Polypeptide-76 is a recombinant collagen-stimulating peptide produced through molecular farming — a biotechnology process where the peptide sequence is expressed in Nicotiana benthamiana plants (a tobacco species used as a bioreactor) rather than synthesised chemically. This produces a biologically identical pro-collagen fragment with superior structural accuracy. The peptide stimulates Type I and Type III collagen synthesis, the fibrillar collagens responsible for skin firmness and tensile strength, while providing a biotech-derived alternative to animal-sourced collagen fragments.
Q3. What does 'Supercharged Hyaluronic Acid' mean in the context of Hydrinity Renewing HA Serum?
A3. The Hydrinity Renewing HA Serum uses a multi-molecular-weight Hyaluronic Acid system — meaning it contains HA molecules of different sizes for hydration at different skin depths. High-molecular-weight HA (>1,000 kDa) sits on the skin surface and creates a moisture-retaining film; medium-weight HA penetrates the upper epidermis; and low-molecular-weight HA (fragments below 100 kDa) reaches the deeper epidermal layers where it provides hydration signals and anti-inflammatory activity. This layered approach, combined with the encapsulation or delivery technology implied by the 'supercharged' designation, provides more comprehensive and lasting hydration than a single-weight HA serum.
Q4. Who should use Hydrinity Renewing HA Serum and at what age?
A4. The Renewing HA Serum is most relevant from the mid-30s onward, when both natural HA production and cellular renewal rates decline measurably, and when progerin accumulation begins to contribute to visible aging. However, those in their late-20s with early signs of dehydration, loss of firmness, or first fine lines will also benefit from the preventive action of the peptide complex. It is appropriate for all skin types including sensitive skin — neither the peptides nor the HA carry irritation risk, and the formula is free of fragrance and harsh preservatives.
Q5. How should Hydrinity Renewing HA Serum be applied in a skincare routine?
A5. Apply the Renewing HA Serum to clean, slightly damp skin (HA absorbs environmental moisture as well as skin moisture, so applying to damp skin enhances its hydrating effect). Use 3–5 drops, press gently into the skin across the face and neck, and allow to absorb for 60 seconds before applying a moisturiser or SPF. In the morning routine, follow with SPF50+ — the peptides and HA are not photosensitising, but protecting them with SPF ensures the collagen-stimulating work performed overnight is not immediately offset by daytime UV damage.
