| Verdict | The renewed version of BIOHEAL BOH's bestselling Tightening Collagen Serum — 45,000 micro-collagen capsules, 12 peptides, plus PHA and LHA for the gentle exfoliation that handles pore visibility. Clinical testing claims 37.2% pore size improvement and 40.2% pore volume improvement after just two weeks of daily use; even allowing for marketing-friendly numbers, the actives stack supports real performance. Targets both horizontal and vertical pore enlargement (the actual mechanism for what looks like 'sagging pores' on mature skin). Lightweight, non-sticky, suitable for daily AM/PM use across most skin types. | LHA (capryloyl salicylic acid) is salicylic's larger, lipid-soluble cousin — gentler, more targeted, and better for maintenance than its parent acid. Rovectin's ampoule pairs LHA 0.1% with standard salicylic 0.4% in a niacinamide + centella base, making it a full-spectrum spot-and-sebum treatment that won't wreck the barrier around the blemish. The quiet-but-effective K-beauty alternative to harsh Western acne serums. |
