Skin boosters improve surface skin quality and hydration \u2014 their effect on deep structural hollows like nasolabial folds is limited. HA filler is the appropriate treatment for fold depth correction.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Can HA filler improve skin dryness and dullness?<\/div>\n<div class=\"faq-a\">Minimally. HA fillers primarily restore volume and contour \u2014 while HA has inherent hydrophilic properties, the placement depth and target volume differ fundamentally from skin boosters. For skin quality improvement, boosters are the right tool.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">For a first-time aesthetic treatment, which should I choose?<\/div>\n<div class=\"faq-a\">Depends entirely on your primary concern. Dullness, dryness, or lack of luminosity \u2192 skin booster. A specific structural hollow (nasolabial folds, tear troughs) \u2192 HA filler. Tell your physician your top concern and let them guide the recommendation.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Can both be done in the same visit?<\/div>\n<div class=\"faq-a\">Yes, and it’s common at Rappoel. The physician plans the overall treatment sequence to ensure the two injection planes and zones don’t interfere with each other.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Which lasts longer \u2014 skin booster or HA filler?<\/div>\n<div class=\"faq-a\">HA fillers generally last longer (6\u201318 months depending on site). Rejuran skin booster effects last 3\u20136 months per session \u2014 but Rejuran’s PDRN provides cumulative tissue-level improvements across a multi-session protocol.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">If I only have one day in Seoul, which is more worth it?<\/div>\n<div class=\"faq-a\">Depends on your primary concern.
