Skin tightening is any treatment that firms loose skin by stimulating collagen and elastin, the proteins that give skin its bounce and that the body makes less of every year. At Radiance East Bay Aesthetics in Pleasanton, it is done without surgery, with RF microneedling, LaseMD Ultra, Sculptra or Rejuran salmon DNA, on the face, neck and body, chosen at a complimentary skin consultation with Darinka Morfin, LE, or Zayda Yeoh, NP. Results build over weeks to months as new collagen forms, so this is a plan rather than a single visit, and the firmness it produces is your own.
Skin stays firm because collagen and elastin fibres hold it up from underneath. As those fibres degrade, skin loosens and lines settle in, first around the eyes, mouth and neck. Five things speed it up:
The areas treated most are the face, the neck and jawline, the abdomen and the thighs.
What we treat
Ultrafine needles plus radiofrequency energy that reaches the deep dermis and remodels collagen from within, firming the jawline, neck, jowls and crepey skin, and it works on the body too: chest, arms, knees and abdomen. Most patients see an early glow within ten days, visible tightening after four to six weeks, and continued improvement for up to six months, with three sessions the usual course.
View treatmentA non-ablative fractional laser that stimulates collagen and elastin deep in the skin, restoring firmness to the face, neck and body, including post-weight-loss laxity. Sessions take 20 to 30 minutes, with mild redness for a day or two, usually in a series of three to four.
View treatmentAn injectable collagen stimulator for firming and volume in larger areas: the cheeks, temples, jawline and a sagging chin. Results develop over three to six months as new collagen forms and can last up to two years, with two to three sessions the usual course.
View treatmentA regenerative booster applied after microneedling or LaseMD Ultra for skin that has lost elasticity and firmness, with firmer texture and deeper hydration developing over two to four weeks.
View treatmentThe appointment
Darinka or Zayda assesses how much laxity there is and where, and tells you honestly what a non-surgical treatment can do for it. Mild to moderate looseness responds well; the consultation is where you hear whether yours is in that range. You leave with the treatment she recommends, how many sessions it takes and what it costs. Skin consultations are complimentary.
RF microneedling is done after numbing cream and feels warm and prickly. LaseMD Ultra is mild tingling or warmth, nothing more. Sculptra is injected with a fine needle or cannula, with numbing available.
One to three days of redness or swelling after RF microneedling, a day or two after LaseMD Ultra, a few days of mild swelling or tenderness after Sculptra with a short daily massage routine. Sunscreen daily.
Collagen takes time. Firmness builds over four to six weeks after microneedling and laser sessions and keeps improving for months; Sculptra unfolds over three to six months. Maintenance sessions extend the result.
Candidacy
You are likely a good candidate if you:
If the concern is lost volume more than loose skin, hyaluronic acid filler restores it immediately. If it is sun-worn texture and spots, start there.
Cost
The cost depends on which treatment suits your skin, the size of the area (a jawline and a full abdomen are different numbers), how many sessions the plan calls for, and whether a booster such as Rejuran is added. Darinka or Zayda gives you the exact cost at the consultation and nothing is booked before then. 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.
Non-surgical skin tightening firms loose skin by stimulating your own collagen and elastin rather than cutting and lifting. At Radiance East Bay Aesthetics that means RF microneedling, LaseMD Ultra, Sculptra or Rejuran, none of which involve incisions or a long recovery. It is an alternative to a facelift for mild to moderate laxity.
Yes. The neck and jawline are among the most treated areas. RF microneedling firms sagging jowls and crepey necks, and LaseMD Ultra treats the face and neck together. Both are safe for all skin types.
Mild to moderate looseness can. LaseMD Ultra treats post-weight-loss laxity on the face, neck and body, and RF microneedling firms the abdomen, arms and other body areas. The consultation tells you honestly whether your looseness is in that range.
It depends on the treatment. RF microneedling results keep improving for up to six months, with maintenance every six to twelve months to extend them. Sculptra's collagen stimulation can last up to two years. LaseMD Ultra results are sustained with skincare, sun protection and periodic maintenance.
Not much. RF microneedling is done after numbing cream and feels like a warm, prickling sensation. LaseMD Ultra is closer to mild warmth with some tingling. Sculptra injections are mildly uncomfortable, and numbing is available.
The cost depends on the treatment, the area, the number of sessions and any booster added. The exact cost is set at the consultation once Darinka or Zayda has seen how much laxity there is. Members receive their discount on aesthetic treatments, and a payment plan can spread the cost of a series.
