Your Best Face co-founder and chief formulator, Darrell Owens, says that if you could only have one YBF product pick Prep. It’s a multitasker – an antioxidant-packed exfoliator and mask – that, by prepping the skin, enhances the effectiveness of products that you follow it with.

New Prep ($80 in the shop) has a smoother, creamier consistency than the old formula with ultrafine crystals that leave skin feeling gently polished. It is a fantastic pore closer and the way it leaves my skin looking can become addictive.

The new formula has YBF’s latest favorite ingredient, Tego Pep 4-7. It is based on the peptide tetrapeptide-17, which is supposed to have collagen-, hyaluronic acid- and fibronectin-boosting activity. Another great addition is Relistase, a tripeptide that inhibits elastase activity and boosts collagen 1 synthesis. It has also been designed to treat sagginess and restore firmness to the skin. Spicy turmeric, with its powerful antioxidant activity, has also been included along with natural skin lighteners, aspen and licorice.

What I really appreciate with YBF is that the new formulas never throw out the baby with the bathwater. The actives that are tried and true are still here, including collagen-boosting Matrixyl 3000, and free radical scavengers, spin trap and Lipochroman-6.

I use it not just on the face, but also the neck and décolleté. I’ve always liked Prep, but now I love it.
