Why Didn’t Youbai Su Fade My Spots Even After a Full Month of Use?

If you’ve slathered on Youbai Su every day for a month but still stare at the same stubborn spots in the mirror, don’t rush to toss the bottle aside. The lack of obvious results doesn’t mean the product is useless—it means you’re probably missing key pieces of the spot-removal puzzle, and one month is often just the warm-up phase before your skin starts showing changes.

Let’s break down the reasons why your spots haven’t budged yet.

First, your skin’s melanin turnover cycle is longer than you think. Most people know the epidermis renews every 28 days, but that’s only true for teens and 20-somethings. As we hit 25+, this cycle slows to 35 days or more. Youbai Su works by stopping melanin production and helping your skin shed old, pigmented cells—but if your cycle is 35 days, after one month, those fresh, less-pigmented cells are still hiding under the surface. You won’t see them until the cycle completes; it’s like waiting for a seed to sprout: you water it daily, but it takes time to push through the soil.

Second, you’re canceling out the effect with inconsistent use or skipped sun protection. Many people treat Youbai Su like a casual step—skipping it on busy nights, dabbing a tiny dot instead of covering the entire spot, or forgetting sunscreen during the day. UV rays are the biggest melanin trigger: if you use Youbai Su to reduce existing pigment but let the sun make more, you’re emptying a bucket with a hole in the bottom—you’ll never get it dry.

Third, your spots are deeper than the product can reach in one month. Not all spots are the same: a fresh acne mark sits on the surface and fades fast, but melasma, long-term sun spots, or age spots are rooted in the dermis (the deeper skin layer). Youbai Su’s active ingredients need time to penetrate through the epidermis to these layers and break down accumulated melanin. One month is barely enough for the ingredients to start working there—you can’t erase years of pigmentation in 30 days.

At the end of the day, spot removal is a marathon, not a sprint. Youbai Su isn’t a magic wand. If you’ve used it correctly (consistently, with enough product, and paired with sunscreen), give it another month or two. Your skin is working behind the scenes, and the day you notice those spots lightening will be worth the wait.
