Caratfill is the injectable line from KS Sungsun International Co., Ltd., a Korean company that has been building the brand since 2017. The range now spans facial and body filling, skin repair and contouring, and the four products stocked here cover the two halves of that: three cross-linked hyaluronic acid fillers with lidocaine, and one polynucleotide-and-hyaluronic-acid booster.
The filler products are separated by density and by the depth they are meant to occupy, which is the useful way to think about them. Caratfill does not run a numbered ladder like some Korean brands; it names each product after the job it does. KISS is for lips. Deep is for folds and mid-face volume. Sub-Q is for structure. Once you read the names that way, the range is easy to order from.
The odd one out is Aurora, which is not a filler at all and sits with the skin boosters. It is bought by clinics adding a PN course to a menu that already runs dermal fillers. All of these are professional-use devices for administration by trained, licensed injectors.
The Caratfill range
Caratfill KISS
The lip product. Cross-linked hyaluronic acid with lidocaine, formulated soft enough to integrate with lip tissue rather than sit as a defined mass, so it gives shape and hydration without the stiff look that a firmer gel produces in the vermilion. The lidocaine matters more here than anywhere else in the range — the lip is the least forgiving area in aesthetics for patient comfort.
Caratfill DEEP
A high-density gel for mid-to-deep wrinkle correction and volume. It is the product for nasolabial folds, cheek volume and chin work, and its cross-linking is tuned to resist migration so the shape stays where it was placed. Deep is the syringe most clinics use most often.
Caratfill Sub-Q
The densest gel in the range, intended for the subcutaneous plane where the filler is carrying structural load rather than smoothing a line. Cheeks, chin and jawline — the places where you want projection and a defined edge. Sub-Q is positioned as the longest-lasting of the three fillers, which follows from its density.
Caratfill Aurora
The booster: polynucleotide with hyaluronic acid, supplied as 10 ampoules of 5.2 ml. Alongside sodium hyaluronate and copper tripeptide it carries a long amino acid profile and extracellular matrix components, which is why the box is large — it is a course product for face, neck and décolletage rather than a single-session correction. Clinics use it for hydration, tone and texture, and as the maintenance layer under a filler programme.
How to choose
The three fillers are a straight density ladder. Pick by plane first, then by how much the tissue has to be held up.
| Product | Type | Density | Plane | Presentation | Typical use |
|---|---|---|---|---|---|
| KISS | HA filler + lidocaine | Soft | Lip tissue | Prefilled syringe | Lip volume, contour, hydration |
| DEEP | HA filler + lidocaine | High | Mid to deep | Prefilled syringe | Nasolabial folds, cheeks, chin |
| Sub-Q | HA filler + lidocaine | Highest | Subcutaneous | Prefilled syringe | Jawline, cheekbone and chin structure |
| Aurora | PN + HA booster | — | Intradermal, distributed | 5.2 ml x 10 ampoules | Face, neck and décolletage courses |
A clinic starting with Caratfill typically opens with DEEP and KISS, adds Sub-Q once it is doing regular contouring work, and brings in Aurora when it wants a booster course to sit alongside filler cases. Injection depth, technique and volume per site should follow the manufacturer's instructions for use.
Storage and shipping
Store Caratfill syringes below 25 °C, out of direct sunlight, and do not freeze. Aurora ampoules are kept cool and sealed until use. Everything stays in its blister and outer carton until the point of treatment. We ship from Seoul with the manufacturer's lot number and expiry date printed on the original packaging.
Buying Caratfill from MY SKIN KOREA
We buy Caratfill in Korea and dispatch from Seoul in original KS Sungsun packaging with full remaining shelf life. Nothing is repacked or relabelled, and every box carries traceable lot and expiry details. Sitting in the same market as the manufacturer means short lead times and honest stock answers.

Frequently asked questions
Who makes Caratfill?
KS Sungsun International Co., Ltd., a South Korean company established in 2017.
What is the difference between Caratfill Deep and Sub-Q?
Deep is a high-density gel for mid-to-deep wrinkle correction and mid-face volume. Sub-Q is denser again and goes into the subcutaneous plane for structural contouring of the jawline, chin and cheekbones.
Is Caratfill Aurora a filler?
No. Aurora is a polynucleotide and hyaluronic acid booster supplied as 10 x 5.2 ml ampoules. It improves skin quality; it does not create volume or contour.
Do the Caratfill fillers contain lidocaine?
KISS, Deep and Sub-Q are cross-linked hyaluronic acid formulated with lidocaine. Aurora does not contain lidocaine.
Which Caratfill is best for lips?
KISS. It is the only product in the range formulated specifically for lip tissue, and its softer consistency is what keeps the result from feeling firm.
How many ampoules are in a box of Aurora?
Ten, at 5.2 ml each — a full course rather than a single treatment.
Do you ship Caratfill internationally?
Yes, worldwide from Seoul with tracked courier. Tell us your destination and we will confirm what we can send before you place the order.
