Still going to bed with makeup on? Stop right now, thank you very much.

Spice Girls star Mel B admits that that’s what she was doing for years — but now that she’s in her 50s, she told The Post, she’s smarter about skincare and washes it off before bed.

That’s not the only change she’s made for her health and wellness.

Getting older has brought a slew of changes to her daily life — from diet to the sudden night sweats, brain fog and anxiety of menopause.

Putting time aside for herself — like by meditating — “can make the world of difference,” the global pop star said.

“It’s just having your brain stop for a second, because as a mother, or as a woman that’s in her 40s, 50s, we’re constantly doing this and doing that, and it feels like it’s for everybody else,” Mel, whose full name is Melanie Janine Brown, told The Post.

She also hops in a sauna and ice bath for some contrast therapy, and finds being around nature while living on a farm “is just so relaxing, good for your mind and your soul.”

While she’d turn to junk food when she was younger and touring, she’s always thought of herself as more of an intuitive eater by listening to when she’s actually hungry and picking the foods she really, really wants.

“If I’m craving red meat, I’ll have some red meat,” she explained. “If I’m craving a salad, or if I’m craving pasta, I’ll listen to my body, and I don’t deny it, and luckily, I don’t overindulge on anything too much.”

One change she has made? Adding weight lifting to her exercise routine, one major way to prevent natural muscle loss as we age.

Not only can strength training build muscle, it can also help prevent osteoporosis and bone loss, and assist the metabolism when it otherwise starts to slow down.

But she still holds the same philosophy about doing the things that make her body feel good, despite her age.

“I know that it’s actually feeding my body the right stuff that it needs,” she said. “And I think the older you get, you want to be more in tune with your body, and more kind of good and healthy to your body, because it starts from the inside out, not the other way around.”

And while she was all about promoting “girl power” in her pop group days, she’s now taking a new approach to what power means, especially as she’s focused on advocating against domestic violence.

“Now, for me, it’s more like ‘woman power’ and having that voice that women feel sometimes that they can’t have,” she explained. “So I’ve gone from girl power to woman power.”

After receiving a Member of the Order of the British Empire (MBE) from the Queen in 2022 for her services to charitable causes, Brown continues to speak up against taboos women face, from abuse to menopause.

She thought she was alone when she first started experiencing symptoms of “the change,” but soon found out that friendship never ends — in all aspects of life.

“It’s like, ‘Oh, well, does anybody else have it?’’And [I] find out all the Spice Girls have it,” she previously told The Post, promoting Revive Collagen‘s latest line of subscription menopause supplements, Menopause Max.

While she may no longer align with the “girl power” of her youth, one label she certainly doesn’t shy away from is power in knowing herself better as she’s gotten older and wiser.

“It’s about just embracing who you are,” she said. “And it’s not being a feminist hitting men, it’s just being a woman and knowing your worth.”
