This nifty little tube of serum contains a total of 1% RetiStar alongside 0.5% Granactive Retinoid, which should really smooth and brighten. The slow-release formulation means you should avoid the most annoying, typical side-effect of a little retinol on your face: peeling. The effects of this retinol serum should be more gradual, building up over time gently and effectively.

The Inkey List retinol serum is currently completely sold out on Cult Beauty, according to their Instagram. Desperate fans have formed a queue in their comments, asking when it'll be back in stock. There's a waiting list on Cult Beauty and they'll notify people when it's available again.

If you do get your hands on a dose of this retinol, remember the golden rules of incorporating it into your skincare regime : Only ever use a pea-size amount on your face, start off by using it just a few times a week as your skin gets used to it, and always slap on some sunscreen because it makes your skin more sensitive to sunlight.

Otherwise, go forth and get your glowiest skin yet.
