Linda Lowndes
Microskin Founder
As the founder I dedicated over a decade to researching and developing a breakthrough formula designed to transform lives. My work was driven by a commitment to help those living with incurable skin conditions and individuals suffering from melanoma. I travelled internationally to source the highest quality ingredients, attended leading cosmetic science conferences, and worked tirelessly to perfect a product that could provide both protection and confidence. Sunseal and Microskin were created with a singular purpose—to give people the ability to live their lives without the constant fear and limitations caused by the sun.
