Melasma is a form of hyperpigmentation that shows as flat, symmetrical brown patches on the cheeks, forehead, nose and upper lip, most often in women, and it is triggered by hormones and sun. At Radiance East Bay Aesthetics in Pleasanton, it is treated with LaseMD Ultra or a medium-depth chemical peel, chosen at a complimentary skin consultation with Darinka Morfin, LE, or Zayda Yeoh, NP. Because melasma darkens with sun exposure, the plan covers protecting the result as carefully as producing it.
Melasma happens when the skin makes too much melanin in patches, and four things drive it.
The patches are usually flat, not raised, with irregular borders, and they tend to appear on both sides of the face at once. Melasma is harmless, but it is often persistent even with careful sun protection, which is why creams alone frequently stall.
One thing worth saying at the consultation: if you are on hormone therapy, mention it. Zayda prescribes it here and can weigh the two together.
What we treat
A non-ablative fractional laser that reaches into the skin to break up excess melanin at its source without damaging the surrounding tissue. It is safe for all skin types and designed to minimize the risk of post-inflammatory pigmentation, which is what makes it suitable for melasma when many lasers are not. Sessions take 20 to 30 minutes, with minimal downtime.
View treatmentThe Perfect Derma Peel is a medium-depth peel built for melasma, sun damage and deeper pigmentation, with a glutathione blend that brightens as it exfoliates. Full results are typically visible within one to two weeks, and the peel is suitable for all skin types.
View treatmentIPL is the treatment for age spots and sun damage, not melasma, and it is not used on very dark skin tones. The consultation is where the safe choice for your skin gets made.
The appointment
Darinka or Zayda examines the patches, asks about pregnancy, contraception, hormone therapy and sun habits, and confirms that what you have is melasma rather than another kind of pigmentation. You leave with a recommended treatment, a session count and the cost. Skin consultations are complimentary.
LaseMD Ultra feels like mild tingling or warmth. A peel tingles while it works and is neutralized and cleansed off at the end of the visit.
Mild redness for a day or two after the laser, a few days of flaking after a peel. Broad-spectrum sunscreen every day is not optional with melasma; it is half the treatment.
Pigment lightens over the weeks after each session as the skin renews. LaseMD Ultra is usually a series of three to four sessions spaced four to six weeks apart, and maintenance visits keep the patches from returning.
Candidacy
You are likely a good candidate if you:
If your dark spots are single and on sun-exposed skin rather than patches, they are more likely age spots. Not sure which kind of pigmentation you have?
Cost
The cost depends on the treatment chosen, how many sessions the plan calls for, and how much of the face is affected. A peel and a laser series are different numbers. The exact cost comes from Darinka or Zayda at the consultation, with nothing booked until you have it. Members receive a discount on aesthetic treatments. Payment plans are available.

Questions
Still unsure? The skin consultation is complimentary, and Darinka or Zayda will answer anything this page does not.
Melasma appears as flat, blotchy brown patches, light to dark brown, usually on the cheeks, forehead, nose and upper lip. The patches have irregular borders and tend to show up symmetrically on both sides of the face. They are not raised and they are harmless.
Sun exposure and hormonal changes are the two main triggers. UV light stimulates melanin, and pregnancy, birth control pills, hormone replacement therapy and thyroid problems can all start the patches. A family history and a darker skin tone raise the likelihood.
Often not. Melasma is persistent even with careful sun protection, which is why treatment exists. It is harmless, so treating it is a choice, but it is a choice with good options.
LaseMD Ultra is. It is safe for all skin types and designed to minimize the risk of post-inflammatory pigmentation, which is the risk that makes some other lasers unsuitable for melasma. The consultation confirms it is the right choice for your skin.
At Radiance East Bay Aesthetics it is LaseMD Ultra or a medium-depth chemical peel. The laser breaks up melanin below the surface; the peel removes the pigmented top layer and brightens. Darinka or Zayda recommends one at a complimentary consultation, based on how deep and how widespread your melasma is.
A LaseMD Ultra session takes 20 to 30 minutes, with only mild tingling or warmth and minimal downtime. A peel visit is similar in length. Both fit into a workday.
