Many patients have unwanted dark spots on their face. These dark spots may have been apparent since birth, resulted from exposure to the sun, appeared after childbirth, or appeared with age. Dr. Michael Lin is a medical doctor and board-certified dermatologist who has done extensive research in the field of pigmentation. He has developed several techniques that combine laser technology, chemical peels, liquid nitrogen, special instruments, and topical medications to lighten and remove dark spots.

Our Hyperpigmentation Treatment Philosophy

What causes Hyperpigmentation?
Hyperpigmentation is caused by an overproduction of pigment called melanin. The two main types of hyperpigmentation are post-inflammatory hyperpigmentation and melasma. Pot-inflammatory hyperpigmentation typically occurs after an injury to the skin and the skin reacts by making extra pigment. The type of injury could be from physical trauma, such as a cut, rubbing, or a burn. Or the injury can be from an inflammatory rash or irritant. Melasma on the other hand is typically hormonal and can occur after childbirth or with oral contraceptives. But, melasma can be worsened by skin injury or sun exposure.
Common Types of Dark Spots and their Treatments

There are many different types of dark spots and each type requires a different treatment. The four most common types will be discussed. The first type is the spot that started at birth or in childhood. These are called “nevi”. The pigment in the nevi is very deep and typically requires laser treatments. The second type of dark spot is the “lentigo”. These spots usually appear on the face and arms and are the result of sun exposure. These spots can also be deep, so a combination of laser treatments, chemical peels, and topical medications is necessary. The third type is “melasma”. This type is also called “the mask of pregnancy” because it appears shortly after pregnancy as a result of hormonal changes and occurs on the face in a mask-like distribution on the cheeks. Finally, the fourth type is called a “seborrheic keratosis”. This type occurs with age and can occur more frequently in areas of sun exposure. The seborrheic keratoses can be flat or bumpy like a wart. These can be removed with special instruments that scrape and burn them off.

Dr. Lin's Customized Skin Lightening Program

Dr. Lin has developed a customized program designed to help most people out with their dark spots. This program can lighten or remove dark spots and even out the skin texture.

Dr. Lin combines multiple treatment modalities, which include chemical peels, topical medications, and laser treatments. Dr. Lin uses beta-hydroxy acid as a peeling agent to begin the process. The peel removes the top layer of the skin and allows the whitening topical medication to penetrate deeply. The next step is the topical medication. These medications were developed by Dr. Lin as a total skin care regime to remove dark spots. Throughout the treatment course, the patient’s progress will be monitored and treatment will be tailored to the patient’s needs during the treatment course.

How to Treat Especially Deep Dark Spots

If dark spots are especially deep or thick, Dr. Lin may use a laser, liquid nitrogen, or special instruments to remove the spots. The laser works by targeting the dark pigment in the spot and destroying it. The liquid nitrogen works by freezing and destroying the cold sensitive pigment cells. The special instruments work by physically scraping off the surface of the dark spot and burning the base.

Dr. Lin also works with the Profractional and Matrix lasers, which have dramatically improved the treatment efficacy in certain skin types’ pigment disorders. The laser selectively treats certain portions of the skin, allowing the surrounding skin to heal around the treated skin areas. This reduces the risk of scarring, hyperpigmentation, and the length of downtime.

Long-Term Treatment

The foundation for a long-term treatment plan for hyperpigmentation is a good skin care regimen. A vitamin C cleanser and moisturizing sunscreen with broad-spectrum SPF coverage of 30 or higher is beneficial. A hydroquinone based bleaching cream to lighten the skin is the most effective method to rapidly lighten the dark spots. There is some controversy requiring the safety of using high dose hydroquinone, so we try to minimize the use. Adding chemical peels, microdermabrasion, intense pulsed light, and lasers can help improve the hyperpigmentation faster.

IPL to Lighten Dark Spots

IPL uses short blasts of a polychromatic, high intensity light to penetrate just below the skins surface creating collagens, plumps up the skin, and creates more elasticity in the skin. Note: Multiple treatments may be required. Skin texture will continue to improve over 6-12 months.


I was seen by Dr. Lin a couple of times to resolve some facial dark spots and uneven skin tone and wrinkles. He took his time listening and figuring out the best course of action for my sensitive skin and my lifestyle. He was thorough finding out about my medical conditions. We chose to do IPL laser treatments in the office and fading cream at home. It has been three months and my face is clear and spot free. I also notice great improvement in reduction of fine lines and wrinkles and overall texture. I am very happy with results. I cannot say enough positive things about Dr. Lin and his hard working staff. Yes, they are a very busy practice and sometimes there is a little wait, but good things are worth waiting for! For one, I want a doctor that takes his time with his patients to be thorough, instead of taking a quick glance and rush out.
