Loose underarm skin can develop because of aging, changes in body weight, genetics, reduced skin elasticity, or changes in muscle mass. Although exercises and healthy habits cannot completely remove significant excess skin, they may improve the appearance of the area by building underlying muscle and supporting overall skin health.
Exercise cannot directly tighten loose skin, but strengthening the muscles underneath the skin can make the upper arms appear firmer. Resistance exercises can help build muscle in the triceps, shoulders, and surrounding areas.
Examples include:
The American College of Sports Medicine recommends resistance training as part of a balanced fitness routine, with exercises adapted to an individual's fitness level.
Healthy habits can support normal skin structure and overall appearance, although they cannot eliminate substantial excess skin.
Consider:
Sun exposure contributes to premature skin aging and loss of elasticity. The American Academy of Dermatology recommends broad-spectrum sunscreen with an SPF of 30 or higher for exposed skin.
Certain dermatological and cosmetic procedures may temporarily or gradually improve the appearance of mild to moderate skin laxity. Depending on the treatment, technologies may use radiofrequency, ultrasound, or other forms of controlled energy to stimulate changes in the skin.
The American Academy of Dermatology notes that non-invasive skin-tightening procedures can produce some tightening, but results are generally more modest than surgical procedures.
Potential options may include:
Results depend on factors such as age, skin condition, degree of laxity, and the specific technology used.
The best approach depends on whether the concern is primarily loose skin, reduced muscle tone, excess body fat, or a combination of these factors.
Before considering a cosmetic procedure, discuss:
A board-certified dermatologist or other appropriately qualified healthcare professional can evaluate the skin and explain realistic options.
Sudden changes in the appearance of the underarm area may have causes unrelated to ordinary skin laxity. Persistent lumps, swelling, pain, skin changes, or other unusual symptoms should be evaluated by a healthcare professional rather than treated as a cosmetic concern.
It is also important to have realistic expectations. Exercise can strengthen muscles, but it cannot remove significant amounts of excess skin. Surgical procedures generally produce more substantial results when there is considerable excess skin.mproving loose underarm skin without surgery usually involves a combination of resistance training, healthy lifestyle habits, sun protection, and, when appropriate, professionally supervised non-invasive treatments. Exercise may improve muscle definition, while dermatological procedures can provide modest tightening for some people. However, results vary and significant excess skin may not respond substantially to non-surgical methods.
