Stretch marks are one of those skin concerns that almost everyone deals with at some point, whether from growth spurts, pregnancy, weight changes, or muscle gain, yet very little honest information exists about why they are so stubborn or what actually helps. If you have tried oil after oil and cream after cream in McMurray or Canonsburg with little to show for it, there is a real reason for that, and it has to do with how stretch marks form in the first place.
This article breaks down the biology behind stretch marks and explains how SkinPen microneedling addresses them differently than topical products alone. Updated August 2026.
Stretch marks develop when skin is stretched faster than its collagen and elastin fibers can keep up with, causing those fibers to tear in the deeper layer of skin known as the dermis. This is why they commonly appear during periods of rapid change, such as pregnancy, adolescent growth spurts, significant weight fluctuation, or fast muscle growth from strength training. The tearing itself is a structural change, not just a surface discoloration, which is a big part of why surface creams have such a limited effect.
Most over the counter stretch mark products work on the very outer layer of skin, but because stretch marks form from damage in the dermis, a layer far below where topical ingredients can meaningfully reach, these products can improve hydration and the look of the skin's surface without doing much for the underlying tear itself. This is why so many people report using a product faithfully for months with only mild, if any, visible change.
To some extent, yes. Fresh stretch marks often start out reddish, pink, or purple because they are still going through an active healing phase with visible blood vessels near the surface. Over months to years, they typically fade to a lighter, silvery, or white tone as that healing process completes. However, the textured indentation, where the skin sits slightly lower than the surrounding area, usually does not resolve on its own even after the color fades.
Skin tone, genetics, and the specific location on the body all play a role in how visible stretch marks end up being long term. According to information published by the Cleveland Clinic, family history is one of the strongest predictors of who is more likely to develop noticeable stretch marks, which explains why some people go through the same physical changes as others with very different results.
SkinPen creates a series of controlled micro injuries in the skin using fine, sterile needles, which triggers the body's natural collagen production process in the exact area being treated. Because stretch marks are fundamentally a collagen and elastin structural issue, this approach reaches the layer of skin where the actual damage occurred, rather than staying on the surface the way topical products do.
A typical session begins with topical numbing to keep the area comfortable, followed by the microneedling treatment itself, which usually takes well under an hour depending on the area being treated. Afterward, skin may appear pink or mildly swollen for a day or two, similar to a mild sunburn, before returning to normal.
Because stretch marks involve deeper structural change, most providers recommend a series of sessions, often spaced four to six weeks apart, to allow collagen remodeling to build progressively. Many patients notice smoother texture and improved tone over the course of several months rather than after a single visit.
People with stretch marks in earlier stages, meaning those with a reddish or purplish tone, often respond especially well, though more mature silvery marks can also see meaningful textural improvement. A consultation with the team at Ageless Skin and Beauty can help set realistic expectations based on the age, location, and appearance of the stretch marks being treated.
Yes. SkinPen is also commonly used for fine lines, acne scarring, and overall skin texture, which means many patients address more than one concern during the same course of treatment. Ageless Skin and Beauty offers SkinPen alongside RF Microneedling for patients who want the added benefit of radiofrequency energy for firmness concerns.
Can SkinPen completely remove stretch marks? SkinPen cannot guarantee complete removal, but it is commonly used to meaningfully improve the texture, tone, and overall appearance of stretch marks over a series of sessions.
Does SkinPen work better on new stretch marks or old ones? Both can improve, but earlier stage stretch marks that are still reddish or purple often respond somewhat more noticeably than very old, mature silvery marks.
Is SkinPen treatment for stretch marks painful? Topical numbing is used beforehand, and most patients describe the sensation as mild pressure rather than significant pain.
How long before I see results from SkinPen on stretch marks? Visible improvement typically develops gradually over several months as collagen remodeling progresses, rather than immediately after a single session.
Is SkinPen safe for stretch marks on different areas of the body? SkinPen can be used on various areas, though a provider will evaluate the specific location and skin condition during a consultation to confirm suitability.
Stretch marks are an incredibly common part of being human, but that does not mean you have to accept them exactly as they are if their appearance bothers you. Understanding that they are a structural change, not just a surface issue, explains why creams alone rarely deliver the results people hope for.
