A mini arm lift (also called a limited incision brachioplasty) may slightly improve the appearance of stretch marks, but it’s not a reliable or complete solution if your primary concern is stretch marks alone. Here's a breakdown based on your situation: What a Mini Arm Lift Does • Tightens mild to moderate skin laxity in the upper arm, often through an incision hidden in the armpit • Removes excess, sagging skin, typically near the upper inner arm • May slightly smooth and reposition the skin, which can reduce the visibility of stretch marks in that localized area Will It Help with Stretch Marks? Yes, a mini arm lift might reduce the appearance of stretch marks near the top of your arms but only where skin is actually excised or tightened. However • Stretch marks lower on the arm won't be affected, since a mini lift doesn't remove or significantly tighten that area. • Stretch marks are in the dermis, not just on loose skin so even with skin removal, they often remain visible, just sometimes stretched or flattened. Considerations • If your skin laxity is only in the upper third of your arms, and the stretch marks are mostly there too, you may benefit. • If your stretch marks extend well below the armpit area, a full arm lift may be more effective but that comes with longer scars. • Other treatments for stretch marks (microneedling, RF microneedling, fractional lasers, scar camouflage tattooing) might be better primary or complementary options.
