This 4-Acid Lion Pose Serum Finally Got My Stubborn Sun Spots to Fade

Editor’s Note: Perimenopause left me with dark spots that nothing seemed to fade, no matter how much I spent. Then I tried Unspotted 4X by Lion Pose. Keep reading to learn about my experience, or jump to my final verdict.

My Skin Before Lion Pose Unspotted 4X

For most of my life, my skincare routine was the one I learned at the Clinique counter as a teenager: cleanser, toner, moisturizer, and done. I was a sun-worshipper in the ’90s, and SPF was something I used on beach holidays, not as a daily habit.

Then I hit my mid-40s. Perimenopause arrived, and with it came brown spots across my cheekbones and one stubborn patch above my lip that concealer never quite covered. My skin had changed the rules overnight, and my old routine couldn’t keep up.

So, I went to the derm counter. I bought a SkinCeuticals serum because it’s the name everyone trusts, and I used it faithfully for months. My skin felt nice, but my spots looked the same.

Next came retinol, then a prescription tretinoin. But on my skin, both meant redness, flaking, and stinging. I’d stop; my skin would calm down, but the spots would still be there. I looked into in-office treatments, but between the patience-testing waitlists and prices, I wanted to find something that worked at home first.

Then I read about Unspotted 4X by Lion Pose in an interview with Mindy Kaling. She’d had retinol wreck her skin right before the Met Gala, and she was blunt about what she uses now: “The entire reason I have good skin is because of this brand.”

So I did my own research. Its 4.8-star rating* stood out, with reviewers in their 40s, 50s, and beyond describing sun spots and age spots they’d had for years finally fading. They referred to it as a “chemical peel in a bottle,” and it had also won Allure’s Best of Beauty and Oprah’s Best Dark Spot Serum.

That was six months ago. Here’s what has changed between then and now.

My Skin After Discovering Lion Pose Unspotted 4X

What stood out to me first was that Unspotted 4X doesn’t rely on one ingredient to do everything.

It uses a 15% blend of four acids: azelaic, tranexamic, glycolic, and lactic, plus the antioxidant glutathione. Glycolic and lactic exfoliate the spots you can already see, while azelaic and tranexamic go after pigment at the source, working from both directions. 

It was developed with Harvard dermatologists and clinically tested in an independent lab, and the results were what convinced me to try it. In the study, 94% of participants saw a reduction in dark spot size, 93% saw smoother texture, and 86% noticed a more even skin tone after 4 weeks, with visible results in as little as 2 weeks.** Just as important for me, it’s formulated to be gentle enough for sensitive skin, with no retinol and no tretinoin.

And at $79, Unspotted 4X costs a fraction of what I’d already spent chasing my spots (like SkinCeuticals, SkinMedica, and Alastin, which regularly cost between $150 and $250)

What Actually Happened, Week by Week*

• Night 1: A light tingle, which I’d read was normal. My skin felt softer the next morning.
• Week 1: My skin felt smoother, and my foundation went on better. The tingle settled down.
• Week 2: The first real fading on my newest spots, right on the timeline the clinical study promised. The patch above my lip looked softer around the edges.
• Week 4 and beyond: The older, set-in spots finally started to give way too.

But the biggest difference for me has been that I no longer dread photos. I’m not layering three serums and hoping one of them works, and my skin isn’t fighting me every time I try something new.

Final Thoughts

If your skin changed in your 40s and nothing you’ve tried has kept up, this is the one I’d point you to. Lion Pose understands what changes after 40. Hormones, decades of sun, and skin that reacts more than it used to all mean you need a treatment that’s effective and gentle. That’s exactly what I couldn’t find before. Unspotted 4X is the first dark spot serum I’ve ever finished and reordered.
