What we wouldn't give for smooth skin and a bright complexion. Surely having fresh looking skin, free from blemishes or signs of ageing, must be the key to happiness. If so, maybe happiness can be found in REN's Steady Glow Daily AHA Tonic.

It certainly peps the skin up, with its brightening, clearing and clarifying solution. It uses azelaic acid to specifically tackle the problem of dull looking skin; this is a toner that won't be happy unless your skin glows. AHAs stimulate the resurfacing power of the skin while lactic acid and willow bark provide tone, helping to reduce fine lines and minimise pores.

This exfoliating toner is gentle enough to be used twice daily, helping you rid the skin of dead cells and boost luminosity for that lit from within look.
