Lierac Protocols offer tailored solutions for various skin issues, featuring two complementary products: an instant remedy and a long-lasting treatment. ANTI-STAIN PROTOCOL – A Long-term Approach The Serum delivers a dual benefit: it not only corrects existing dark spots but also prevents new ones from appearing, regardless of their source (whether related to age, sun exposure, or acne). Central to this formulation is an optimal concentration of Pure Niacinamide (Vitamin B3), which dermatologists endorse, paired with stabilized Vitamin C and keratolytic Floral Acids. This combination effectively reduces the size, quantity, and visibility of dark spots. Users can expect improvements in skin tone within just one month, resulting in a more uniform and radiant complexion. Composed of 93% naturally-derived ingredients, this lightweight serum features a non-greasy, non-sticky feel, making it ideal for everyday use in any skincare regimen. It is designed to accommodate all skin types, including those with sensitivity.
