Think that the Un-Wrinkle couldn't get any better? Peter Thomas Roth Un-Wrinkle Foundation takes the powerful wrinkle-fighting peptides found in the original serum and adds in light-diffusing pigments and SPF 20 sun protection. It immediately gives you luminous skin and overtime firms and smooths the skin while protecting from future damage. It is oil and fragrance-free, making it great for all skin types. Light is ideal for those with fair to light skin tones.
