Creams or Laser for Hyperpigmentation: Which Fits Your Dark Spots

Start with what is causing your dark spots

Maybe you have tried a few fading products and the spots are still there, or new ones keep showing up as old ones fade. Before you compare creams and lasers, it helps to know what kind of spot you have and what keeps triggering it.

The AAD says getting rid of hyperpigmentation begins with finding the cause. If you can remove it, many spots clear on their own and new ones stop forming. Acne, eczema or psoriasis needs to be treated first. A skin or hair product that burns or stings may be the trigger. If you think a prescribed medicine is causing spots, the AAD says not to stop it, but to ask the doctor who prescribed it.

The type of spot also matters. Melasma, sun spots and marks left after acne respond differently, and the guide melasma vs. sun spots vs. PIH explains how to tell them apart.

Sunscreen comes before anything else

According to the AAD, effective treatment for dark spots begins with sunscreen. It recommends a tinted sunscreen with iron oxide, which helps protect against visible light, another cause of dark spots. For melasma, the AAD advises a broad-spectrum sunscreen with SPF 30 or higher, worn throughout the day.

The AAD's routine is simple: apply sunscreen to all skin that clothing will not cover, reapply every two hours and after swimming or sweating, wear a wide-brimmed hat, and try to stay out of the sun between 10 a.m. and 2 p.m. Used this way, sunscreen can prevent new dark spots and help clear existing ones. Without it, creams and lasers have to work against a trigger that never stops.

Creams and other products you put on your skin

Creams are the usual next step after sunscreen. They are slower than procedures and need steady use, but they carry less risk of side effects. Here is what official sources say about the main options:

• Non-prescription ingredients. The AAD lists azelaic acid, glycolic acid, kojic acid, retinoids such as retinol or adapalene gel, and vitamin C. These can fade existing spots, and some can slow the skin's production of pigment.
• Hydroquinone. The FDA says that since the 2020 CARES Act, over-the-counter skin lightening products with hydroquinone are treated as new drugs that need FDA approval before they can be sold, and that there are no FDA-approved or otherwise legally marketed over-the-counter skin lighteners. You can get a prescription product with hydroquinone from your health care provider. The FDA has received reports of rashes, facial swelling and skin discoloration called ochronosis, which may be permanent.
• Prescription combinations. For melasma, the AAD describes tretinoin with a mild corticosteroid, a triple combination cream, and, for hard cases, tranexamic acid as a cream or pill. If tranexamic acid comes up, tell your provider if you have ever had a blood clot.
• Products to avoid. The FDA says mercury is banned in skin lighteners and warns against products with handmade labels, labels in other languages or no label at all. The AAD reports that some imported products contained steroids or mercury not listed on the label.

Peels, microneedling and laser

The AAD says procedures, including laser therapy and chemical peels, tend to work faster than creams. They also cost more and have a higher risk of side effects. For age spots, the AAD says one or two laser treatments can treat the spots quickly, with longer-lasting results than a fading cream, though lasers can cause crusting or temporary darkening that fades.

Melasma is a different story. The AAD describes chemical peels, microneedling and laser or light treatments as add-ons for people already using medicine and sun protection, and says a few studies found that adding laser can improve results in that situation. A StatPearls review describes a conservative approach that saves lasers for selected stubborn cases, to limit dark marks and rebound darkening. For marks left after acne or injury, another StatPearls review says peels and lasers, including picosecond lasers, should be used cautiously because they can cause irritation and more hyperpigmentation.

Laser Eraser treats hyperpigmentation and melasma with the PicoWay® picosecond laser. Its melasma page says laser alone is rarely the whole answer for melasma, and that the plan almost always includes strict sun protection and, where appropriate, creams your physician may recommend or coordinate.

Relapse: why dark spots come back

Treatment fades the spots you have, but the triggers do not go away. The AAD notes that you cannot cure all forms of hyperpigmentation, though you can work to prevent it from coming back. It says creams can fade melasma but cannot make it go away forever, and that it commonly returns after time outdoors without sun protection. A StatPearls review describes melasma as chronic and relapsing.

Other dark spots can return too. The AAD says age spots can come back after any treatment unless you protect your skin from the sun, and that while you can get rid of dark spots and patches, new ones can form. Keeping up sunscreen, gentle products and treatment of the underlying skin condition is how you protect the result.

How to pick a starting point

Every case is different. When you are ready to talk to a provider, the checklist in questions before scar treatment helps you get a clear plan. These patterns from AAD guidance can help you think it through first:

• A confirmed age spot you want gone quickly: a laser may be an option, after a dermatologist has confirmed it is an age spot.
• Melasma: daily sunscreen and creams usually come first. The AAD suggests seeing a dermatologist if a non-prescription product has not helped within three to six months.
• Dark marks from active acne: treat the acne first, protect your skin, and give the marks time, since many fade once breakouts stop.
• Pregnant: the AAD advises waiting until after the baby is born to treat melasma, which may also fade on its own after birth.
• A spot that is new, changing, bleeding or itching: get it checked first, as the guide get a spot checked before laser explains.
