How long does it take to address skin issues?

There really isn’t a fixed standard. I’ve been working in the field of skin care for 6 years, and I’ve seen cases where sensitive redness caused by acid treatments resolved completely within 2 weeks, as well as cases of rosacea that took over a year of treatment to stabilize. On average, acute issues affecting the superficial layers of the skin usually show noticeable improvement within 2 to 4 weeks. For more chronic problems that involve the dermis or have accumulated over time, it’s common to see results taking 3 months to 1 year. As for scars or deep pits already formed, relying solely on topical skincare products is not enough; medical treatments are often necessary and should be followed according to a prescribed regimen.

Think about it: in healthy young skin, the epidermal renewal cycle is approximately 28 days. As people age beyond 30, this process slows down, and the cycle can extend to 40 days or even longer. Minor issues that occur on the surface of the skin—such as temporary redness and bumps from acne, dark spots caused by sun exposure, or mild irritation from using the wrong products—can coincide with one of these renewal cycles. As long as you stop exposing your skin to irritants and use the right products, these problems will resolve quickly on their own. Previously, a sophomore girl came to see me because she had blindly followed the blogger’s advice and used high-concentration salicylic acid products. After applying them for three days straight, her entire face developed closed comedones and became extremely irritated; she even couldn’t use facial cleanser. I advised her to stop using any topical treatments with therapeutic effects and instead use only mild repairing creams and ceramide serums. When going out, she had to rely on masks and hats for protection against the sun. She was very compliant and even gave up her favorite iced milk tea for almost half a month. On the 22nd day, she came back to show me the before-and-after photos: all the redness had gone away, and the only remaining closed comedones were a few scattered ones on her temples—almost impossible to notice.

You might say it happened so quickly, but actually, last year I met a guy who worked in sales. He had been suffering from persistent acne for almost 8 years—his cheeks and chin were covered in hard nodules, and there were also deep red scars left by the acne. He had been using various popular acne treatments on his own, including some that contained hormones, without knowing it. As a result, his skin had developed resistance to these treatments. When I started working with him, there wasn’t much change in the first month; only the new pimples stopped appearing. At one point, he even considered giving up, wondering if my approach was wrong. But with patience, he persisted until the third month. By then, most of the inflammation had subsided, and the scars began to fade gradually. After nearly 10 months of treatment, his skin is now almost completely clear, with only a few faint traces left that are barely noticeable unless you look very closely.

Currently, there are two opposing claims circulating online: one claims that “acne can be eliminated in 7 days and the skin can be whitened in 14 days,” while the other argues that “it takes at least half a year to truly improve the skin.” In fact, both views are extreme. Those who claim that you can solve whole-face skin problems in just a few days should be taken with a grain of salt. Either they are referring to single, newly appearing red bumps that can be reduced in size quite quickly with high-concentration anti-inflammatory serums within a couple of days, or they are claiming that recurring acne all over the face or spots that have been present for several years can be eliminated in just a few days. In either case, it’s very likely that these products contain corticosteroids or heavy metals, which temporarily suppress the inflammation and make your skin look better, but once you stop using them, the problems will return even more severely ； If it takes half a year for any treatment to show results, it might be because the approach being used is not appropriate for your specific condition. If the treatment isn’t targeted at what’s really causing the problem, no amount of time spent on it will be effective—it will only waste your time.

To be honest, taking care of your skin is just like growing succulents—you can’t expect new leaves to sprout the very day after you water them, right? The problems you’ve accumulated over years from staying up late, eating a lot of greasy and spicy food, and never using sunscreen can’t be resolved just by applying some skincare products for a few days. Besides using the right products and maintaining a healthy lifestyle and diet, avoid constantly changing your skincare routine needlessly, and your recovery will definitely speed up.
