Le Mieux Retinol Serum uses a combination of peptides and retinol to drastically fade signs of aging. It's designed to tighten, resurface and renew dull, aging and overexposed skin; and smooth rough, dry skin. It works to revitalize pores, restore broken tissue and minimize the appearance of fine lines and wrinkles by promoting collagen production and cellular turnover. It's ideal for all skin types and especially for lines, wrinkles, uneven tone, dullness and sun damage. Its three-tier delivery system lowers potential for skin irritation.
