Our Sally-Ann Creed® Retinol Serum is a must! This 0.5% concentration is a high potency Vitamin A derivative that is known to improve skin appearance as well as skin cell health due to its amazing ability to improve skin cell turnover along with collagen production. As we age our skin’s collagen stores break down, resulting in a saggier, more wrinkled appearance. Retinol is able to prevent collagen breakdown while improving both the frequency and quality of collagen production. Retinol is also able to unclog pores, inhibit the overproduction of sebum – which has been linked to acne and severe breakouts – and reduce the appearance of dark spots. Incorporating this serum, in conjunction with a Vitamin C serum, is a winning duo resulting in a radiant, age-defying complexion!
