It should be said that most of them can be cured.
As for the specific treatment method, it depends on the extent of the lesion, the duration of the disease, and the location. Treatment with phototherapy or topical medication cannot be expected to work quickly. For most of the treatment, at least three months to six months to adhere to, to judge whether it is effective or ineffective! Therefore, the treatment of vitiligo needs patience.

Melasma and freckles

You should pay attention to sun protection when you go out.
Q: How are freckles and melasma caused?
A: It is not very clear! The occurrence of freckles has certain genetic factors and is related to ethnicity, the incidence of which is higher in Western Caucasians than in Yellow! The etiology of melasma is complicated, and it is related to endocrine factors, such as pregnancy (so also called gestation spot), dysmenorrhea, chronic hepatitis (so also called liver spot), etc. Sunlight can make freckles and chloasma more obvious! Therefore, they are often light in winter but heavy in summer.

In the former case, use a cream containing hydroquinone (such as Thousand White) externally to protect from the sun, and take tranexamic acid orally, 500 mg per day. The latter can be treated by laser.
Q: Can I get rid of freckles with advertised products?

It is better to find a few people who have used the advertised products and ask her/him how they feel.

Q: My child’s facial rash, tried many kinds of skin cream, the rash improved significantly. But I found that the child’s face suddenly became very dark, why is this ah?
A: There are two possibilities for blackness, one is post-inflammatory hyperpigmentation, which will soon fade. The second is due to poor quality drugs, resulting in melanosis! It is more trouble. So you should check the origin of the skin cream, whether there is “ID” (referring to the approval number of the relevant state departments). Don’t use topical medications of unknown origin and without exact identity! I say again and again, as long as it is used on people, we must be careful! As for the darkening of your child’s skin belonging to that kind, you still have to ask your local doctor to determine.
Q: What medication can speed up the fading of hyperpigmentation after eczema? There is no such thing as hyperpigmentation that does not fade away for life?
A: Many inflammatory conditions are followed by hyperpigmentation. It occurs when the pigment synthesized by melanocytes in the epidermis enters the dermis due to inflammation and is swallowed by phagocytes as a “foreign body”! These pigments are gradually digested or transported away by the phagocytes, which takes a process, but will eventually restore your skin’s original color. Therefore, post-inflammatory hyperpigmentation will slowly and eventually fade away. Vitamin C and vitamin E are both oxidizing agents and can be used internally or externally to help promote the fading of pigmentation.
Superficial Pigmented Hairy Mole
Q: A 24-year-old male has two palm-sized brownish, rough, hairy skin on his left back shoulder. It does not hurt or itch. It seems to be there only when it was developing. What is this? Should I treat it?
A: This is a superficial pigmented hairy nevus, which usually appears when you are 16 or 17 years old, and you are already 24 years old, so this nevus will not increase in size! Superficial pigmented nevus is not uncommon, and some of them can grow hair on top. There is no conscious discomfort and it will not become cancerous! No treatment is necessary. The effect of using laser to remove the spot is not satisfactory. The good thing is that the mole mostly grows on the part that can be covered by clothes.

Q: Male, 24 years old, a few years ago, I was persuaded by a friend to make a large tattoo on my forearm. Now I regret it, is there any way to erase the tattoo?
A: Tattoos can be largely removed with a laser. However, multiple treatments are required. It is easy to get a tattoo, but not so easy to remove it, and the cost of removing it may be much higher than the cost of the tattoo. Young people, tattoos need to think twice before you do it!!!
