District Flowers are what it means to experience what is a messy flower. I am fascinating~
However, the one that makes the district's eyes shine the most is our Taiwanese girl Ye Shuhua .
is originally a walking reflector . She is born with cold white skin , against the backdrop of the platinum hair color, it seems like a beautiful god is coming.
When the light hits, it is so white that it is different from other team members.
The figure is also much tighter to the naked eye. sweeps away the shadow of the previous storefront .

lipstick , never consider whether the color number will look dark.
Do color-treating homework , and you don’t have to stick to the word “whiteness”.
Double Eleven has arrived, and it also means that is the most suitable season for whitening : it is here! Previously, Qu Hua promised his family's whitening dry information to popularize science. It is time to put it on the agenda~
After reading this article, you will get:
, The process of melanin production , The principle of whitening ingredients
. Distinguish which ingredients are real big shots and which are marketing celebrities!
, high reputation whitening product (no wide)
Without further ado, let's just start!
Can people become whiter indefinitely?
said straight to the point, won't. Because whiteness has a limit,
There is a famous principle in basic chemistry called LeChatelier’s Principle. It describes the equilibrium of chemical reactions.
From this principle, the melanin in the skin in will be suppressed to a certain amount of at most. After reaching this amount, no matter how many whitening products are used, they will not become whiter.
For the upper limit of your whiteness, sisters can refer to The inner side of the upper arm and chest and abdomen that cannot be sunbathed .
If this part is still healthy wheat color, then Don’t set your whitening expectations too high , otherwise even the ingredients of beer must be said: I can’t do it!
And, because melanin functions are to protect our skin from UV damage.
The melanocyte density of parts like face, back, joint is higher than that of other parts , and it is difficult to be as white as other parts.
So, whitening must be [down-to-earth] !
If you insist on using the whitening product to 8 days (one skin renewal cycle) , it still has not turned white.Either the sun protection is not done well, or... will not be white again...
Do you still need sun protection in autumn and winter?
The culprit for turning black is the exogenous stimulation of such as ultraviolet rays.
If you want to be white, first needs to reduce the impact of ultraviolet rays on the skin from the root to avoid a series of subsequent chain reactions to the greatest extent.
Although the temperature in autumn is lower than in summer. But [hot] and [sun] are not proportional. If UV index is greater than 3, you need sun protection.
And in winter, just like in spring, the amount of ozone in the air is very low, causing UVA to become stronger . In addition, the metabolism of dry and cold air is slowed down, and even is more likely to occur in photoaging.
If you say, do you don’t need sun protection when you stay indoors? District Flower still wants to tell you: UV rays can penetrate glass...
From a practical perspective, Daily activities in autumn and winter , and buying SPF 30, PA ++ sunscreen is enough to deal with it!
The principle of the effect of different whitening ingredients
Before explaining the whitening ingredients, we must first understand how becomes black.
Under the influence of external factors such as ultraviolet , tyrosine in melanocytes will be converted into dopa under the action of tyrosinase . dopa has undergone some complex reactions and is then transferred to keratinocytes, thus becoming black.

From this picture, sisters can clearly see several key steps for darkening of their skin. The principle of the different whitening components is that interferes with one of the steps , thus breaking the link is to "pop"!
Specifically, there are four categories of whitening ingredients:
, inhibition: Inhibit the activity of tyrosinase
Star ingredients are: arbutin , 377, kojic acid, turbidden Acid
, Reduction: Reduced melanin product Doba
Star ingredients are: VC and its derivatives, glutathione, Resveratrol

, intercept: hinders melanin transport to epidermis
Star ingredients are: nicotinamide
, Metabolism: accelerates the shedding of epidermal melanin
Representative components include: fruit acid, salicylic acid , vitamin A...
like the fourth type of ingredients, fruit acid, salicylic acid .
In addition to alleviating closed acne. For melanin that reaches the cuticle, and they will also help accelerate the shedding of , whitening and rejuvenating the skin.
However, the fourth category of is generally just auxiliary , not as the main ingredient.
Another example is the third type of [nicotinamide] that prevents melanin from transporting. It is also the most well-known whitening ingredient in recent years.Many sisters feel that once nicotinamide is discontinued, is prone to blackening.
That’s right, This is not an illusion! Because in the process of nicotinamide, melanin has produced , which just hinders its transport to keratinocytes.
has a little understanding of nicotinamide, and must also know that "long hair" rumors have always been following you.
Yes, this is not wrong, because
And the nicotinamide ingredient is basically all whitening ingredients, which is cheap . It contains the residual impurity niacin during purification, which may also cause irritation to the skin.
So, despite the popularity of nicotinamide, the truth about the truth of the japanese flower is:
. Don’t blindly pursue high concentrations. If you have html more than 15%, don’t buy !
. Pay attention to nicotinamide purity when purchasing. Avoid impurities niacin irritation
, Cheap is its biggest advantage , which is why daily chemical companies are hyping how great it is
Speaking of this, you can basically stamp the marketing attributes of niacinamide ~
