Speaking of stains, I believe many people are troubled by it. In order to eliminate stains, freckle removal products do not buy less, but this has to be cautious, some "products" have a very good whitening freckle removal effect, but in fact, may be over-added heavy metal mercury. Therefore, when buying whitening products, the first guarantee is formal.
However, it is difficult to get rid of stains by relying on functional skin care products.
"Stains" is a generic term, in fact, it has many types, treatment methods and difficulties are also different, so don't rush to "chop" to buy spot removal products, or first solve the common types of stains:
Freckles
Freckles are the most common epidermal stains, which appear from an early age, usually < 5 mm, brown to dark brown round, oval and polygonal spots, clear realm, isolated and non-fused, mostly considered to be an autosomal dominant skin disease.
Freckles are common in exposed areas, especially in the nose, cheeks, upper back, and shoulders, and in severe cases, they can affect the extensor side of the forearm and the back of the hand, and it can be aggravated by the sun.
Freckles are also the best to remove the color spots, through the aurora DPL, IPL, YAG laser and other treatments, can be removed, and there is no rebound, that is to say, there will be no recurrence in situ. However, if the sun protection is not done well, freckles may continue to grow in other parts.
