SkinMedica Lytera® 2.0 Pigment Correcting Serum 60ml is a brightening serum formulated to address the appearance of stubborn skin discoloration and uneven-looking skin tone. Its lightweight formula can be applied to the face, neck, chest and other affected areas to help improve the appearance of dark spots, sun-related discoloration, post-blemish marks and dullness for a clearer, more even-looking complexion.

Lytera® 2.0 features a non-hydroquinone pigment-correcting formula. According to available product information, it combines tranexamic acid, phenylethyl resorcinol, niacinamide, Tetrapeptide-30 and phytic acid to help support a more balanced-looking complexion and improve the appearance of uneven tone and visible discoloration.

Tranexamic acid and phenylethyl resorcinol help correct the appearance of hyperpigmentation, while niacinamide and Tetrapeptide-30 help support a more even-looking skin tone and reduce the appearance of new spots. The formula also contains grape flower cell extract, plankton extract, Artemisia Capillaris flower extract and marine fermentation extracts. Together with phytic acid, these ingredients help promote a brighter, smoother and more radiant-looking complexion.

This serum is listed as suitable for all skin types and tones. Available product information describes the formula as hydroquinone-free, retinol-free, paraben-free, fragrance-free and non-comedogenic. Use twice daily and apply broad-spectrum sunscreen during the day to help minimise the effect of UV exposure on the appearance of discoloration.
