@_domibeauty: Do you also have problem areas such as elbows? My elbows tend to get dark due to constant friction & contact on my chair & desk. So I decided to try this Teashell Niacinamide Brightening serum on my elbows to see if this serum could help me with my problem area. #teashell #TeashellNIacinamide #TeashellBrighteningserum #TikTokShop22doubleup
