“Skin booster” has become an umbrella covering very different injectables, and choosing by trending name usually disappoints. The honest way to choose is by mechanism: what does each family actually make your skin do? GLOW Dermatology in Cheongdam maps the whole landscape in one practical guide.
The hydrators and the repairers: HA and PN
Hyaluronic acid boosters (classic skinboosters) bind water in the skin; their job is hydration, fine dehydration lines and glow, and effects are pleasant but the shortest-lived. Polynucleotide (PN) boosters like Rejuran work deeper in biology: derived from salmon DNA, they calm inflammation and rebuild the skin’s repair environment, which makes them the choice for damaged, thin, post-acne or reactive skin.
The collagen builders: PCL and PLLA
Gouri (liquid PCL) and sculpting-class PLLA products do not add moisture; they switch fibroblasts into collagen production. Results arrive over weeks and sessions, rewarding patience with structural firmness, the right family when the complaint is looseness and lost bounce rather than dryness. Juvelook (PDLLA-based) straddles categories, popular for pores and fine texture including acne-scar-prone skin.
Exosomes and how doctors actually combine
Exosome products, regenerative signal particles applied with microneedling or injected, aim at overall skin condition, calming and recovery acceleration, often paired after lasers. In practice clinics rarely pick one family forever: a typical sequence stabilizes skin with PN, builds with PCL, and maintains glow with HA or exosomes. The order is prescribed by skin assessment; the menu above is just the map.
GLOW Dermatology in Cheongdam carries all major booster families and selects by examination rather than trend, consulting international patients. Bring your skin complaint rather than a product name; the map above turns into a one-line answer at assessment.
