A Korean peptide-based brightening skin booster that targets melasma, hyperpigmentation, and uneven skin tone while improving hydration and overall skin quality.
PROSTROLANE BLANC B is a peptide-based brightening skin booster developed in South Korea by Caregen Co., Ltd., designed to treat melasma, hyperpigmentation, uneven skin tone, post-inflammatory hyperpigmentation, and skin dullness while also improving hydration and overall skin quality. Unlike traditional hyaluronic acid fillers, BLANC B isn't intended for facial volumization. Instead, it combines a low concentration of hyaluronic acid with biomimetic peptides that target melanin production and promote brighter, healthier-looking skin.
BLANC B's key innovation is its biomimetic peptide complex, laboratory-designed peptides that mimic naturally occurring signaling molecules in the body. They're intended to regulate melanin production, improve skin repair, support collagen synthesis, enhance hydration, reduce inflammation, and improve overall skin tone through cellular signaling pathways, rather than chemically inhibiting melanin formation the way conventional whitening agents do.
BLANC B also contains approximately 0.7% non-cross-linked hyaluronic acid, which helps hydrate the skin, improve elasticity, support peptide delivery, and enhance smoothness. The HA serves primarily as a carrier and moisturizer rather than providing structural volume.
A typical course is 3 to 5 sessions, every 2 to 4 weeks, with maintenance every 4 to 6 months depending on skin condition and pigmentation recurrence. Protocols vary by clinic and may be adjusted to the severity of pigmentation.
Because these risks exist with any injectable or energy-based treatment, procedures should only be performed by trained, licensed medical professionals with expertise in facial anatomy.
PROSTROLANE BLANC B is marketed internationally through aesthetic distributors and used in many professional aesthetic clinics. Regulatory approval varies by country, so practitioners verify local registration and approved indications before clinical use.
PROSTROLANE BLANC B occupies a specialized niche among injectable skin boosters by focusing on pigmentation management and skin brightening rather than facial volume restoration or broad collagen stimulation. Its combination of low-concentration hyaluronic acid and biomimetic peptides makes it particularly attractive for patients with melasma, post-inflammatory hyperpigmentation, and uneven skin tone. Compared with regenerative PN products such as REJURAN or PROFHILO, BLANC B is more specifically targeted toward pigmentation concerns, though it currently has less published peer-reviewed evidence than those longer-established products.
