Freckles, sun spots, age spots, chloasma, cheekbone spots, Ohta spots... There are so many types of spots, can you tell which are superficial spots and which are deep spots?
In fact, there are big differences in the solutions for different types of spots. For example, deep spots are more troublesome to deal with than shallow spots. As for the method of identifying superficial spots or deep spots, we will not use the depth of color to distinguish, but based on the location of the spots on the skin.
Color spots usually located on the epidermis of the skin are superficial spots, such as freckles, sun spots, age spots, etc. The spots located in the dermis layer of the skin are deep spots, such as dermal chloasma, malar spots, Ohta spots, etc.
The melanin metabolism pathways of superficial spots and deep spots are different.
In terms of treatment, stains located on the epidermis are relatively easy to remove. As long as the activity of tyrosinase is inhibited and the production of tyrosinase is reduced, melanin can be effectively blocked and the metabolism of the skin is accelerated. Melanin will mature along with the epidermal cells. The process slowly moves upwards, and is eventually exfoliated and metabolized along with keratinocytes. Deep spots are more complex and require conditioning both inside and outside the body. Internal conditioning is particularly important. For example, balancing female hormones is very helpful in reducing hormonal spots. ; Increase the detoxification function of the liver and also help eliminate pigment spots; promote the phagocytosis of inflammatory cells, macrophages, to engulf pigment particles and take them away from the skin.
