Kean Beauty Eyelash & Brow Growth Serum Set contains two 3 ml tubes formulated with a natural biotin-based blend designed to support the appearance of lashes and brows. The serum is intended for those who wish to maintain or enhance the look of their lashes and brows in a gentle manner. Its formulation includes nourishing and soothing ingredients suitable for sensitive skin, helping to reduce the risk of irritation often associated with other serums. The lightweight, non-greasy texture allows for easy application along the lash line and brow area without leaving residue. Each bottle offers a measured amount for regular use, making the set a practical option for daily care. The biotin component is included for its recognized role in supporting keratin structure, which is naturally present in hair. This product is not designed to produce immediate or dramatic changes but rather to provide consistent conditioning over time. It is compatible with those who prefer fragrance-free, paraben-free, and cruelty-free formulations. The serum can be applied once or twice daily as part of a routine, with gentle pressure to avoid contact with eyes. As with any cosmetic product, patch testing on a small skin area is advised before full use. This set offers a straightforward approach to lash and brow care without making exaggerated claims about speed or degree of visible results. It focuses on the quality of ingredients and sensitivity of application.
