Hilary Duff treating forehead melasma with toner product

Hilary Duff

Hilary Duff is using a toner product to help target a patch of melasma on her forehead.

The Younger actress, who is mother to son Luca, seven, and 16-month-old daughter Banks, has opened up about her "busy mom" beauty regime in a new tutorial for Vogue.com.

To begin, Hilary noted that she starts her skincare routine by swiping on some of Ole Henriksen's Glow2OH Dark Spot Toner over her face, paying special attention to one particular spot near her hairline.

"One really cool thing that happened to me when I had babies is that I got melasma," she joked. "This is a dark spot toner, so every day I just say a little prayer that it's taking care of that dark spot right there."

Also known as chloasma or pregnancy mask, melasma is a skin condition that commonly affects expectant mothers. It appears darker than the surrounding skin, and usually appears on the forehead, upper lip, cheeks, nose or chin, but can also affect the arms and neck.

At present, there is no cure available, but there are some treatments that may help melasma fade if it doesn't disappear on its own after several months.

Elsewhere in the clip, Hilary discussed how she is loving Glycelene's The Beauty Ointment in French Lavender, a versatile ointment that doubles as a cream and hydration mask.

"When it's super dry in California, (I use) Glycelene - my favourite vegan products. It's ultra-hydrating, made with oils, it has lavender in it. I warm it up (between my palms) for almost 10 seconds. I really love oils, if your skin can handle it, it's quite a treat. I use that as a bit of a serum, even though it's super moisturising," the 32-year-old said, before adding a touch of Glycelene's day cream. "I like to layer them because I like to keep my skin looking dewy."
