Kim Kardashian, 42, revealed her secret struggle with adult acne in her 40s, which she hides ‘very well’ under heavy make-up while delivering SKKN

Kim Kardashian revealed a secret about her skin in an interview with… Refinery29 Wednesday.

The reality TV star, 42, has spoken about her struggle with adult acne and said most people don’t notice it because she keeps it hidden “well under make-up”.

The businesswoman – who recently admitted she was “struggling” as a single mother following her divorce from ex-husband Kanye West – revealed: “Oh, I had whole acne, like complete bouts of it.”

“But I documented it,” she said. “I think if people saw that, they would be really shocked to know that I went through that experience.”

To deal with her acne, she said she started playing with different products and even incorporating ingredients she loves into her luxury skincare brand, SKKN by Kim.

The SKIMS founder said this journey was something she “never thought I would experience in my 40s.”

The Kardashian star also revealed that her skin has become more sensitive over the years and has worked hard to identify the cause of her acne.

“I’m like, ‘Should I stop using oils if I have acne?'” Then she realized that stopping using oil wasn’t helping, she remembers, trying to find products that suited her skin type.

“It may be hormonal or a change in supplements,” she also said. “Every time I change the way I eat or try different foods – I think my skin becomes too sensitive.”

“It’s been really interesting to try new products and see what works for different skin types that I never thought I’d try in my 40s.”

In addition to dealing with adult acne, Kardashian also suffers from chronic psoriasis, something she’s been vocal about in the past.

“I would like to thank my mother for this problem,” she told the outlet. “I’m the only one of her children who got it.”

Regarding the frustrating process of searching for a solution to clear up a chronic rash, she said she still doesn’t know why it happens and has “kind of given up on trying to figure it out.”

“I’m still confused about psoriasis and what it triggers,” she explained.

“Sometimes, I get completely stressed out, and I’ll be completely upfront about my psoriasis,” she continued.

“Sometimes I’ll be as zen as I can be, without a care in the world, and my psoriasis will completely flare up,” she added. “They say it should be the other way around.

“I’ve kind of given up trying to figure it out.”
