Skin Booster

Skin Boosters

A tailored solution that fills the deepest layers of your skin
4.4 Clinic Signature Treatments

After a close analysis of your individual skin condition and concerns, the chief director personally designs a tailored skin booster solution.

There are many kinds of skin booster, and each works in a different way. At 4.4 Clinic we assess your skin condition from several angles and distinguish specific problems such as loss of firmness, dryness, fine lines and enlarged pores. We then analyse the ingredients and mechanisms required and design the solution best suited to your skin.
  • REJURAN HB

    Rejuran HB (PN + HA / hyaluronic acid)

    A Hydro Booster that delivers a dewy, luminous finish

    To the regenerative effect of the original Rejuran Healer it adds hydration and a dewy sheen on the skin's surface — in other words, a glass-skin effect.
    The discomfort that was the major drawback of the original Rejuran Healer is reduced by more than 50% through a blend of local anaesthetic and an appropriate ratio of hyaluronic acid, so even those sensitive to pain can be treated comfortably.
    It is more effective for skin balance, anti-ageing and firmness, and the hyaluronic acid it contains gives the skin more hydration.

    A solution for the renewal of damaged skin

    PN (polynucleotide) is a biologically derived component that promotes skin recovery, contributing to cell renewal and tissue stabilisation.
    It can be used even where the skin barrier has weakened and become sensitive — a low-irritation skin booster from which you can expect calming and restoration together, with minimal irritation.

    SKINVIVE

    A skin booster containing a great many active ingredients

    An upgraded hyaluronic acid gel is injected directly into the cheeks to temporarily improve moderate to deep fine wrinkles.
    It improves skin firmness, rough texture, fine wrinkles and a dull tone, and also enhances hydration — a treatment with long-lasting results.

    Juvelook

    A volume-focused skin booster that supports collagen production

    PLA (polylactide), which promotes collagen production within the skin over time, gradually restores skin texture and firmness.
    Even with changes such as fine lines, enlarged pores and loss of firmness, it supplements volume naturally and refines the skin to be smooth and firm.

    Suited to natural volume replenishment that restores fullness to the skin.

    Elravie RE20
    Skin Booster

    ELRAVIE RE20 (RITUO)

    A high-performance booster that restores the vitality of skin cells through premium regenerative care using ECM components

    Made from acellular allogeneic dermis (hADM) processed into a micronised form, it is a next-generation ECM booster composed of the actual ECM components of skin — not only collagen but also elastin and hyaluronic acid.
    It helps deliver immediate and fundamental improvement, including collagen and elastin within the skin.
    It can improve the dermal environment fundamentally — renewal, firmness, pores — and because it uses patented AlloClean Technology, unlike xenogeneic collagen it is free from immune rejection and side effects.

    Skin Booster

    Ellansé

    A self-generating collagen booster that fills in over time

    PCL (polycaprolactone) microspheres are evenly dispersed through a CMC gel. Immediately after injection the gel carrier supplements volume, and from then on it is designed to induce the skin to produce collagen of its own.
    It suits areas where loss of volume and loss of firmness appear together, and because the characteristics and how the results are maintained differ by formulation (S, M, L), the chief director personally designs the treatment after checking the area and your skin condition.
    Recommended for anyone who would rather see change settle in naturally than be filled all at once.

    AestheFill

    A long-lasting collagen-stimulating filler

    AestheFill is a long-term filler lasting up to two years. It promotes collagen and new tissue formation from beneath the dermis, filling in volume naturally where it is lacking, and is a collagen-stimulating filler whose results can be maintained for a long time.
    Because it is injected deeper than an ordinary filler, beneath the dermis, collagen production within the dermis becomes highly active.

    HiloWave
    Skin Booster

    HiloWave

    A dual hyaluronic acid booster designed to fill and renew together

    A biostimulator-type booster containing both high- and low-molecular-weight hyaluronic acid. The high-molecular-weight component supplements volume where the skin has hollowed, while the low-molecular-weight component conditions hydration and the renewal environment within the skin.
    Its soft formulation means it can be used widely even where the skin is thin, so it is applied to areas such as the mid-face, front cheeks, neck and backs of the hands, where volume and fine lines are both a concern.
    The treatment is carried out using a cannula, and after checking the skin thickness of each area the chief director personally designs the injection depth and dose.

    Revix

    The strength to rebuild your skin's pillars — a next-generation ECM booster

    Human-derived collagen and elastin rebuild skin structure that has broken down, while hyaluronic acid fills in deep hydration and keeps the skin supple. A fine liquid formulation minimises discomfort and clumping, so even sensitive skin can recover firmness and radiance together.

    A PLLA collagen booster that fills in gradually

    PLLA (poly-L-lactic acid) induces a collagen-producing response within the skin, supplementing both the volume of hollowed areas and overall skin density.
    Rather than filling everything at once, it is carried out over separate sessions, with the dose for the next session adjusted as we see the pace of change.
