How to Remove Melanin from the Face

Generally, melanin on the face can be removed through the use of whitening skincare products, photorejuvenation, acid peels, laser treatments, and salicylic acid peels. Detailed explanations are as follows:

1. Use of Whitening Skincare Products

Active ingredients in whitening skincare products can inhibit melanin production, block melanin transfer, or promote melanin metabolism in multiple ways. For example, vitamin C can inhibit tyrosinase activity—tyrosinase is a key enzyme in melanin synthesis—and reducing its activity decreases melanin synthesis; niacinamide can prevent the transfer of melanosomes from melanocytes to keratinocytes, thus reducing melanin content in the skin.

2. Photorejuvenation

Photorejuvenation utilizes broad-spectrum intense pulsed light to irradiate the skin. Light of different wavelengths is selectively absorbed by different tissue components in the skin. Shorter wavelength light primarily targets pigments such as melanin in the epidermis, causing them to break down and achieving the effect of skin whitening and color evening. The general reference price for photorejuvenation is 500-2000 yuan per session. Improvement is typically visible 3-6 months post-procedure, although possible side effects include skin redness, pain, and similar symptoms.

3. Acid Peel

Acid peel involves applying fruit acid solutions of varying concentrations to the skin surface to promote the shedding of the stratum corneum, accelerate the renewal rate of keratinocytes and some superficial epidermal cells, and stimulate the proliferation of elastic fibers in the dermis. At the same time, fruit acid can inhibit melanin formation and reduce pigmentation. The general reference price for acid peels is 300-1500 yuan per session. Improvement is usually visible 3-6 months post-procedure, but may be accompanied by symptoms such as redness, stinging, and itching.

4. Laser Treatment

Laser treatment uses high-energy laser beams that emit extremely short pulses, enabling melanin particles in the skin to absorb large amounts of laser energy within a very short time, rapidly expand, rupture, and turn into very fine fragments. These fragmented melanin particles are then engulfed by macrophages in the body's immune system and gradually metabolized and excreted from the body. The general reference price for laser treatment is 1000-3000 yuan per session. Improvement is typically visible 3-6 months post-procedure, but may be accompanied by symptoms such as redness and pain.

5. Salicylic Acid Peel

Salicylic acid peel involves applying salicylic acid solution of a certain concentration onto the skin surface, loosening the connections between keratinocytes in the stratum corneum, thereby promoting the shedding of the stratum corneum. At the same time, salicylic acid also has certain anti-inflammatory effects, which can reduce skin inflammatory reactions and post-inflammatory pigmentation—that is, melanin formation. The general reference price for salicylic acid peels is 200-800 yuan per session. Improvement is usually visible 3-6 months post-procedure, but may be accompanied by symptoms such as skin redness and stinging.

It is recommended to visit a regular hospital and perform the above procedures under the guidance of a professional doctor to ensure the safety and effectiveness of the procedures. Post-procedure care should include sun protection, moisturizing, avoiding irritation, following medical instructions for skin care, and observing skin recovery.
