"I'm excited about my results. My dark spots are fading"
"This product worked great for me. And I have dry skin so the serum texture was good for me. I did have a little irritation & itch. But that’s cause I’m sensitive to kojic. I used only 2-3 times per week to start. But now everything seems fine."

Tips from Doctor Fay and Our Founders
The Yearn Skin Kojic Acid Serum is ideal for intermediate to advanced skincare users who are focused on fading stubborn hyperpigmentation, post-acne dark marks, sunspots, and uneven tone. Its powerhouse blend—featuring kojic acid alongside niacinamide, alpha arbutin, lactic acid, and glycolic acid—works synergistically to brighten, refine, and even out the complexion . This potent formula is not suitable for beginners, those with sensitive or compromised skin barriers, or anyone with inflamed, broken, or irritated skin. You should always patch‑test and discontinue use if you notice strong irritation or contact dermatitis, and avoid using it without daytime sun protection (SPF) due to increased sun sensitivity .

With consistent use, you can expect to see a brighter, more even skin tone within 4 to 6 weeks. Dark marks, pigmentation, and post-acne spots should begin to fade, while overall clarity and radiance improve. With continued use over 8 to 12 weeks, results become more noticeable and long-lasting, especially when paired with daily SPF and a gentle, supportive skincare routine.
