Gouri·Juvelook·Rejuran Skin Boosters

A procedure that activates the skin's own regenerative ability by directly injecting active ingredients into the dermal layer. 'Gouri', with its liquid PCL component, naturally induces collagen production throughout the face. 'Juvelook', with its PDLLA component, is effective for filling sunken areas and improving pores and scars. 'Rejuran Healer', with its PN component from salmon DNA, regenerates skin cells to improve skin texture, elasticity, and oil-water balance. The most suitable skin booster is selected based on skin concerns and desired effects, and synergy can be enhanced when combined with other treatments like hydro injections or Potenza.
