Injectable HA Skin Booster for Microneedling & Mesotherapy - 3.5ml x 2 Vials
Meso Secret Injectable HA Skin Booster is a sterile, non-crosslinked hyaluronic acid gel at 20 mg/ml, supplied as two 3.5 ml vials per box. It is intended for mesotherapy and is also used in microneedling protocols.
What this product is
- Non-crosslinked hyaluronic acid — a fluid gel, not a volumising filler.
- 20 mg/ml in a clear, colourless, homogenised solution.
- 3.5 ml × 2 vials per box — 7 ml total per box.
- Sterile, non-pyrogenic and biodegradable.
- Viscoelastic — it stays where it is placed instead of running.

Non-crosslinked — and why that matters
Crosslinked hyaluronic acid is engineered to hold shape and add volume. Non-crosslinked hyaluronic acid is not: it is formulated to spread through the dermis as a hydrating gel. If you are looking for volume, projection or structural support in a specific area, this is not that product. If you are looking for hydration, surface quality and a fluid gel that moves through tissue, it is.
How it is used
- Mesotherapy — multi-point microinjection into the dermis. This is the use stated for the product.
- Microneedling protocols — applied in combination with a microneedling device.





Frequently asked questions
How much of a vial is used per session, and can I keep what is left?
Volume per session depends on the treatment area and the protocol, and is decided by the practitioner. A vial is not always fully consumed in one session. Each vial is for single use: discard any product remaining after the session.
How often can an HA skin booster be used?
Interval is set by the protocol being followed, not by the vial. In community discussion of mesotherapy scheduling, the recurring figures people report are roughly monthly for a course, with two weeks described as the shortest sensible gap between certain products. Non-crosslinked hyaluronic acid is generally treated as a product type that can be repeated more frequently than biostimulators. Confirm the interval with the practitioner running the protocol.
What depth and angle is this designed for?
The product is intended for mesotherapy — deposition into the dermis. The exact depth and angle depend on the treatment area, because skin thickness varies across the face, and on the technique used. Depth is set by the practitioner according to the product instructions. Note that the same needle reaches a different depth at 45° than at 90°.
Can it be used under the eyes?
Periorbital skin is thin, and it is the area where practitioners are most conservative. In the community threads reviewed, this is the area that draws the most discussion — some people report deliberately avoiding HA products there, while others use them without issue. Whether to use it in this area, and with what volume, is a clinical decision — the product's stated use is mesotherapy generally, and this listing makes no periorbital claim.
What is the downtime, and will I bruise?
Bruising is reported as common with any needle-based treatment, and more common under the eyes than with a cannula. In the community threads reviewed, users describe swelling lasting a few days with some products and bruising that can still be visible the next day. Practical measures repeatedly mentioned by experienced users include numbing cream, icing the area immediately before treatment as a vasoconstrictor, avoiding treatment before an event, and changing needle tips frequently. Anyone on blood thinners is advised to discuss it first, as bruising risk is higher.
Is this a dermal filler?
No. It is a non-crosslinked hyaluronic acid gel intended for mesotherapy. It is not designed to add volume, project a feature or hold a shape. Products described as dermal fillers are crosslinked for exactly that purpose; this one is not.
How should it be stored, and what is the shelf life?
Store at room temperature. Shelf life is two years from the date of manufacture.
Who should not use it?
Anyone on anticoagulant or blood-thinning medication, anyone with an active infection or inflammation in the treatment area, and anyone with a known hypersensitivity to hyaluronic acid should not proceed without medical advice. This product is for use by trained practitioners.
Before use
