Consumers who are largely wrinkle-free but have developed smile lines can benefit from a cosmetic filler called Evolence.

Evolence was developed specifically to treat smile lines and can gently reduce the appearance of lines within minutes.

According to Dr Gerald Bernstein, a cosmetic doctor at Bernstein Cosmetic Surgery, it is so gentle that the likelihood of bruising is less than with many other fillers.

He told King 5 News: "It produces an immediate result. You put it in and people walk out and they're done."

Evolence is designed to improve and refresh the appearance by restoring the collagen that has naturally been lost during the ageing process.

Made from natural collagen to mimic the skin's own collagen, Evolence achieves natural-looking results by adding structure, strength and volume.

Unlike many other fillers, which require repeat treatments every few months, the effects of Evolence last for up to 12 months.
