@lluvlydebby: If nothing else is fixing your dark elbows, try actual 3D Retinal + NAD+ 😮💨 The skin on our elbows is thick and stubborn, which is why a high-performance formula like Numbuzin No.9 works so well. The retinal speeds up skin renewal to push out hyperpigmentation, while the 50 peptides and ceramides completely smooth out rough texture. Just real K-Beauty results in 7 days. ✨💜 #numbuzinRetiNADChallenge #numbuzin #retinal #nad @numbuzin
