Moisture-focused, Loved01 Brightening Serum is formulated with a proprietary blend (rosehip oil and sea buckthorn oil) of emollient plant-based oils to moisturize and improve the appearance of fine lines and wrinkles. The stainless steel rollerball provides a cool effect and helps temporarily increase localized circulation. In a 28-day in-vitro test, the serum was shown to improve the look of skin texture.
