Stretch mark treatment in New Braunfels, TX is one of the most common cosmetic questions we hear, and radiofrequency microneedling is the option with the most consistent evidence behind it. At Elect Dermatology, Dr. Hockley and Dr. Stahr use the Vivace RF microneedling platform to remodel the collagen beneath striae, whether they came from pregnancy, a growth spurt, rapid weight change, or muscle gain.
What Stretch Marks Actually Are
Stretch marks, known medically as striae distensae, are a form of scar. As the American Academy of Dermatology describes it, when skin stretches or shrinks quickly, the collagen and elastin that support it rupture, and the mark that appears as the skin heals is the visible result of that damage.
They pass through two stages. Early stretch marks, called striae rubra, look red, pink, or purple because the vessels of the dermis show through the disrupted tissue. Over months to years they mature into striae alba: white or silver, slightly sunken, and thinner than the skin around them. That distinction matters more than almost anything else when we talk about what treatment can achieve.
How RF Microneedling Remodels the Skin
Microneedling, sometimes called percutaneous collagen induction, drives very fine needles through the epidermis into the dermis. The controlled micro-injuries recruit fibroblasts and start a wound-healing cascade that lays down new collagen. This is measurable rather than theoretical: in a study of multiple microneedling sessions published in the International Journal of Dermatology, researchers took skin biopsies before and after a treatment series and measured statistically significant increases in collagen types I, III and VII and in newly synthesized collagen. The same group’s objective evaluation of microneedling for atrophic scars found comparable remodeling where scar tissue had replaced normal dermis, which is structurally the same problem a stretch mark presents.
Vivace adds radiofrequency energy delivered through the needle tips. Alongside the mechanical micro-injury, that heat tightens existing collagen and extends the remodeling stimulus deeper into the dermis, which is where the structural deficit in a stretch mark sits. We adjust needle depth and energy to the body area being treated.
What the Evidence Says About Results
The most useful recent data comes from a 2026 controlled study in Aesthetic Surgery Journal. Twenty-nine patients had four microneedling treatments spaced a month apart, and matched untreated skin on the opposite side of the body served as the control. Both red and white stretch marks improved steadily across the series, and improvement kept accumulating between the three-month and six-month follow-up visits rather than plateauing when treatment stopped.
Red stretch marks did measurably better than white ones: Manchester Scar Scale scores improved roughly 44 percent over baseline at three months and 49 percent at six months. Striae alba still improved, but less, and more variably. If your stretch marks are still pink or purple, this is the window where treatment does the most work.
Two things follow from that. First, the series matters more than any single session, and the final result is not visible on the day the series ends. Second, no treatment erases stretch marks. The realistic goal is that the treated skin looks and feels closer to the skin around it, in texture, depth, and color. Any clinic promising erasure is overselling.
What a Session Looks Like Here
Your first visit is a consultation. One of our dermatologists examines the stretch marks, confirms what stage they are in, and sets expectations specific to your skin and the area involved. If you proceed, we apply topical numbing before treatment. The Vivace handpiece then passes over the area, creating thousands of micro-channels while delivering radiofrequency energy at a depth chosen for that part of the body.
Most sessions run 30 to 60 minutes depending on how much area is being treated. Afterward the skin looks pink and feels warm, much like a mild sunburn, typically for 24 to 48 hours. Most patients return to their normal routine the next day. Plan on four sessions about a month apart as a starting point, with the understanding that larger or older areas sometimes need more.
Aftercare That Protects Your Results
For the first three to five days, keep it simple: a gentle fragrance-free cleanser and a bland moisturizer or hyaluronic acid serum. Hold off on retinoids, vitamin C, acids, and physical exfoliants until the skin has settled. Skip pools, hot tubs, and hard workouts for 48 hours.
Sun protection is the part people underestimate. Freshly treated skin pigments easily, so broad-spectrum SPF 30 or higher on any treated area that sees daylight is not optional during the series. In the Texas sun that is worth taking seriously year round, not just in July.
Who Is a Good Candidate
Most people with stretch marks are candidates, and that includes patients across the full range of skin tones. Richly pigmented skin does call for more conservative settings and closer follow-up, because any inflammatory treatment carries some risk of post-inflammatory hyperpigmentation; we treat that as a reason to adjust technique, not a reason to decline treatment.
We do ask patients who are pregnant or breastfeeding to wait until afterward. Active skin infection in the area, certain clotting disorders, keloid-forming tendencies, and immunosuppression all need to be reviewed before we proceed. Isotretinoin use in the recent past is worth mentioning at your consultation as well.
Realistic Companions to Treatment
Consistent topical retinoid use between sessions supports ongoing collagen synthesis and is the most useful thing patients can do at home. For patients whose main concern is overall skin texture and tone rather than the stretch marks alone, we sometimes sequence RF microneedling with other treatments from our aesthetic services, such as chemical peels, at appropriate intervals. Your dermatologist will tell you what is worth combining and what is not.
