How long does it take to restore normal skin color after treating skin problems?

There is really no standard answer to this matter. In the cases I have come across, healthy skin that has just been tanned can return to its original color in about 10 days at the fastest using Prototype Vitamin C Essence + Strict Sunscreen. However, if post-inflammatory pigmentation is superimposed on sensitive skin, there are many people who have left light marks after half a year of tossing.

The reason why the time difference can be so big depends on how your abnormal skin color came about, which layer of the skin the pigmentation is on, and whether you have encountered any pitfalls on the way to conditioning. There was a sophomore girl who went to Sanya for a week during the summer vacation. Her back became red and peeling due to the sun. When she came back, she applied soothing and repairing body lotion every day. She didn’t even wear a sling when going out, and she also took some effervescent tablets containing vitamin C every day. Within two weeks of wearing the backless skirt, the color difference on her shoulders and back was completely gone. Her skin is resistant, but the epidermal pigment from acute sunburn naturally disappears quickly with metabolism.

On the other hand, if the pigment has settled into the dermis, the recovery speed will be completely different. Just like your white quilt, the floating dust on the surface will fall off after a few pats. The stains that have seeped into the seams of the fabric may not be completely clean after repeated scrubbing. The same is true for pigmentation. Last year, I met a girl who suffered from recurring acne for three or four years, leaving a dark acne mark on her cheek. She has sensitive skin that gets red when the seasons change. She followed the trend and used 30% concentration of vitamin C on her face. She didn’t build up a tolerance and didn’t pay attention to sun protection. Within a week, the acne marks became deeper, and her whole face became stinging and rashed. Later, I stopped all whitening products and first nourished the barrier. It took more than three months for the redness to be basically gone. Then I slowly applied mild tranexamic acid + low-concentration niacinamide essence. It took more than two months for the acne marks to completely disappear. It took less than half a year to go out.

Nowadays, there are two opinions on the Internet that are quite quarrelsome. One group says that "successful whitening can be achieved in 28 days." The other group says that "whitening is all an IQ tax, and it is useless no matter how you apply it." In fact, both of them are a bit extreme. 28 days is the normal metabolism cycle of healthy epidermis. If you only have superficial pigment in the epidermis and your own metabolism is normal, and you use the right products and strictly protect yourself from the sun, it is not difficult to see obvious brightening in one cycle. People who say this most likely have good skin and have not suffered any injuries. But if you have pigments in the dermal layer, such as old acne marks and chloasma, it is definitely not something that can be solved in one or two metabolic cycles. Whitening is said to be an IQ tax. Many people either do not choose the right ingredients for themselves, or do not use sun protection, which means that the application is in vain.

What I usually tell people who come for consultation the most is not to worry about other people’s timetables. It’s like getting a scab from a fall. A teenager’s scab will disappear within a week, but a person in his thirties or forties may leave a faint mark and still see it after half a year. Age , skin type, and daily living habits all affect the speed of recovery. If you apply expensive whitening essence, stay up until two or three o'clock every day, and go out in the middle of the day without even wearing a hat, even the magic product will not be able to make you recover quickly.
