Dermatologists typically use lasers on people with dark patches or blotches on their skin. If you want to lighten larger areas, then they’ll probably use a cream or peel instead. Only visit a licensed and certified dermatologist for a laser treatment. Some cosmetic clinics might offer the treatment, but they may not use the best techniques or equipment. Your insurance may or may not cover the treatment, so keep the cost in mind.
Signs of a negative reaction include excessive redness, swelling, burning, and itching. Let your dermatologist know right away if you experience these side effects. If you do have a negative reaction to the laser, then your dermatologist can recommend other lightening techniques.
The treatment might feel a bit prickly or hot, but you shouldn’t feel pain. Let the dermatologist know right away if the treatment hurts you. If you’re having treatment on just a few spots, then the session will probably be shorter. If you’re treating a large area, then it will be longer.
The dermatologist will probably want to examine your skin in a week or 2 regardless to see how you’re healing.
The area will probably be sensitive for a few days, so don’t scrub it hard or use a washcloth. This will be painful if the area isn’t healed yet. Don’t pick at any scabs that form. This could cause a scar.
Follow all of your dermatologist’s care instructions. If they tell you that putting any cream on the area isn’t safe, then listen to them. You could also use a cold compress to relieve the pain if the dermatologist says you can’t use aloe cream.
Even if it’s a cloudy day, apply sunscreen or carry it with you. You never know when the sun might come back out. If the spot is in an area you can cover with your clothes, then you don’t need sunscreen.
Your dermatologist will probably use a light to medium-depth peel to start out with. In general, the lighter you want your skin, the deeper the peel has to be.

Placing acid on sensitive skin could cause a lot of irritation. You may need multiple chemical peels to remove excess melanin. Non-prescription and store-bought chemical peels are not recommended and could be harmful. Only have a chemical peel treatment under a dermatologist’s supervision.
Your skin will be irritated and red for a few days after the treatment. Your dermatologist might tell you to take pain relievers and provide you with washing instructions to help you heal faster. Microdermabrasion is usually only used on small patches, so your dermatologist may use a cream or peel if you want a large area lightened.
The application instructions vary with different products, but in most cases you’ll apply the cream 1 or 2 times per day. Rub it in completely and then wash your hands thoroughly. Keep the cream away from your mouth or eyes. Don’t get the cream on anyone else, or it could bleach their skin. Those with darker skin tones should exercise caution if considering using a product that contains hydroquinone, as it can cause irreversible discoloration and skin darkening.

OTC creams should produce results within 4 months. If you don’t notice any change, contact your dermatologist. Products with a hydroquinone concentration higher than 2% are usually not available without a prescription. This is because hydroquinone could cause health problems in high concentrations and with long-term use. Some countries have banned hydroquinone without a prescription or altogether because of potential health risks.

Kojic acid doesn’t have the potential health risks of hydroquinone, so you can use it if your country has banned hydroquinone. The most common side effect is contact dermatitis. You could also ask your dermatologist for a prescription-strength kojic acid cream.
