Visia scans measure your skin pigmentation, pore size, and porphyrins (evidence of bacteria lodged in pores). It also scans UV spots, sun damage, localized hyperpigmentation, melasma, moles, texture and wrinkles. With this assessment of your skin, we can grade your skin condition relative to others of the same age and skin type. Visia will select personalized recommendations for its built-in library of skin care products and treatments.
