Age spots are flat brown spots on skin that has seen years of sun, most often the face, the backs of the hands, the arms and the shoulders. They are also called sunspots, liver spots or solar lentigines, and they are harmless; they just make skin look older than it is. At Radiance East Bay Aesthetics in Pleasanton, they are lightened with LaseMD Ultra, IPL photofacial or a chemical peel, chosen at a complimentary skin consultation with Darinka Morfin, LE, or Zayda Yeoh, NP. A single spot can be treated on its own.
Age spots are clusters of melanin, the pigment that gives skin its colour. Years of UV exposure, from the sun or tanning beds, push the skin to make more melanin than it needs, and over time the excess gathers into distinct dark spots. The damage accumulates, which is why the spots arrive in your forties and fifties even though the sun that caused them was decades ago.
Other factors add to it. As skin ages, its ability to repair sun damage weakens. Fair skin is more prone. Frequent skin injury or inflammation can cause melanin to cluster, and hormonal changes during pregnancy or from medication can disrupt melanin production and make existing spots darker.
How to tell an age spot: it is flat, not raised, unlike a mole. It ranges from light brown to black, from freckle-sized to a larger irregular patch, and it sits on skin that gets sun.
What we treat
A non-ablative fractional laser that delivers energy into the deeper layers of skin and breaks up the clustered melanin behind each spot, while stimulating collagen so the surrounding skin looks smoother too. It is safe for all skin types, takes 20 to 30 minutes, and recovery is quick.
View treatmentA bright, cooled light that removes brown spots without bruising, with no downtime and no need for numbing. It treats the face, neck, chest, hands and arms, and most patients complete a short series spaced three weeks apart, then a maintenance visit every four months. Not suitable for very dark skin tones or recently tanned skin.
View treatmentA peel removes the pigmented top layer to lighten brown spots and even tone, with the strength chosen for your skin. A deeper SkinCeuticals peel targets sun spots and stubborn discolouration in a single treatment.
View treatmentThe appointment
Darinka or Zayda examines the spot or spots, confirms they are age spots rather than melasma or another kind of pigmentation, and recommends the treatment that suits your skin tone and the area. You leave knowing how many visits and what they cost. Skin consultations are complimentary.
LaseMD Ultra feels like mild warmth or tingling. IPL uses a cooling tip and is comfortable without anesthetic. A peel gives a tingle while it sits on the skin. All three fit into a workday.
Mild redness for a day or two after the laser, none after IPL, some flaking after a peel. Daily broad-spectrum sunscreen on the treated area, including the backs of the hands, which most people forget.
Spots lighten over the weeks after each session as the skin sheds the broken-up pigment. Some spots clear in one or two visits; a whole area is usually a short series.
Candidacy
You are likely a good candidate if you:
If the spots are spread across the whole face alongside redness and rough texture, that is sun damage, and the plan is broader. If the patches are symmetrical and hormonal, that is melasma.
Cost
The cost depends on how many spots you treat and where, which treatment suits your skin, and how many sessions the plan calls for. A single spot on the cheek and both hands are different numbers. Darinka or Zayda prices it at the consultation. Members receive a discount on aesthetic treatments. Payment plans are available.

"I initially started with Zayda to help address my aging skin concerns, ie, age spots, fine lines, wrinkles - just wanted to age a bit more gracefully. As such, we developed a proper skin care plan which soon evolved into a health care plan."
Questions
Still unsure? The skin consultation is complimentary, and Darinka or Zayda will answer anything this page does not.
Years of UV exposure are the leading cause. The sun pushes the skin to overproduce melanin, and over time the excess clusters into flat dark spots on the face, hands, arms and shoulders. Aging, fair skin, past skin injury and hormonal changes all add to it.
No. Age spots are harmless clusters of pigment, flat and not raised, unlike moles. They are treated because of how they look, not because they need to be.
Yes. The backs of the hands are one of the most common areas treated. IPL treats the hands and arms as well as the face, and LaseMD Ultra treats sun-exposed areas wherever the spots are.
At Radiance East Bay Aesthetics it is LaseMD Ultra, IPL photofacial or a chemical peel, depending on your skin tone and how many spots there are. IPL is the quickest with no downtime but is not used on very dark skin tones; LaseMD Ultra is safe for all skin types. Darinka or Zayda chooses at a complimentary consultation.
It depends on the treatment and the number of spots. IPL is usually a short series spaced three weeks apart, then maintenance every four months. LaseMD Ultra usually runs three to four sessions spaced four to six weeks apart. A single spot may need fewer visits than a whole area.
Treated spots lighten, but the same sun can make new ones, so daily sunscreen on the face and hands is part of the plan. Maintenance visits keep the area clear.
