Reasons Your Skin Might Be Stretchy (Hyperelastic Skin)

Have you ever noticed that your skin seems to stretch more than usual or takes longer than normal to snap back into place? While some flexibility in the skin is normal, excessive elasticity, known as hyperelastic skin, may be a sign of an underlying condition affecting collagen production.

Hyperelastic skin is most commonly associated with Ehlers-Danlos syndrome (EDS), a connective tissue disorder that impacts skin, joints, and blood vessels. However, other conditions like Marfan syndrome, certain genetic mutations, and even aging and sun damage can also weaken the skin’s structure, making it appear looser and stretchier.

If you’re concerned about hyperelastic skin, it’s important to understand its causes, potential health implications, and how the right skincare can help improve aging-related skin sagging.

Hyperelastic skin refers to skin that is abnormally loose, stretchy, and fragile due to a defect of elastin in the connective tissue. People with hyperelastic skin can often pull their skin much farther than normal, and it may take longer to return to its original position.

This occurs when the structural proteins collagen and elastin, which gives the skin its strength and elasticity, are weakened, deficient, or improperly formed. 

Since collagen is also found in joints, blood vessels, and other connective tissues, hyperelastic skin is often just one symptom of a broader connective tissue disorder like Ehlers-Danlos syndrome. 

While stretchy skin is not always a medical concern, it can be a sign of an underlying health condition in some cases. 

The most well-known cause of hyperelastic skin is Ehlers-Danlos syndrome, though other conditions and lifestyle factors can also contribute to weakened collagen and overall skin structure.

EDS is a group of rare hereditary connective tissue disorders that affect collagen production. Since collagen is the main protein responsible for skin strength and elasticity, EDS can cause hyperelastic skin, easy bruising, poor wound healing, and fragile blood vessels.

People with classical and hypermobile types of EDS often exhibit the most pronounced hyperelastic skin. Their skin may feel soft, velvety, and fragile, sometimes leading to excessive stretch marks, sagging, or slow-healing wounds. In severe cases, joints and blood vessels may also be affected, leading to chronic pain or increased risk of injury.

Marfan syndrome is another genetic connective tissue disorder and is caused by mutations in the FBN1 gene, which affects the production of fibrillin , a protein that works alongside elastin to maintain skin structure.

People with Marfan syndrome often have long limbs, flexible joints, and a tall, thin body frame, and they may also experience loose or sagging skin due to damaged connective tissue. While skin symptoms are less prominent than in EDS, Marfan syndrome can lead to premature skin aging and decreased skin elasticity over time.

Other conditions and external factors can also contribute to collagen breakdown, leading to stretchier, sagging skin:

• Cutis laxa, which is Latin for “lax skin,” is a rare connective tissue disorder that causes loose, wrinkled skin due to defective elastin. Unlike EDS, the skin in cutis laxa does not return to its original shape after being stretched.

• Certain cancers. Some cancers that affect elastin synthesis can cause the skin to appear looser or more fragile.

• Aging and sun damage. Over time, UV exposure, pollution, and natural aging break down collagen and elastin, leading to increased skin laxity. Unlike genetic conditions, this type of skin sagging is typically more gradual.

• Rapid weight loss. Losing a significant amount of weight quickly can cause the skin to appear stretched and saggy. Depending on the amount and quality of collagen and elastin, the skin may or may not “snap” back into place on its own following significant weight loss.

No, there is no cure for hyperelastic skin caused by genetic disorders like EDS or Marfan syndrome. However, if stretchy or sagging skin is due to premature aging or sun damage, preventative skincare and elastin-supporting treatments may help to slow further elastin breakdown.

Some of the best sunscreens to protect your skin against UV damage include:

If stretchy or hyperelastic skin is caused by aging or sun exposure, some anti-aging skincare ingredients prevent sagging, but none can help to permanently tighten and firm the skin. 

The best anti-sagging ingredients for you will depend on which skin type you are. However, in general, look for research-backed skin-tightening ingredients like exosomes, defensins, retinol, and vitamin C.

A few leading anti-aging skin care products for loose or wrinkled skin include:

Hyperelastic skin is most commonly associated with Ehlers-Danlos syndrome, but other conditions like Marfan syndrome and other connective tissue disorders can also contribute to stretchy or wrinkled skin. While these genetic conditions cannot be treated, skin laxity caused by aging or sun damage can be managed with a customized anti-aging skincare regimen and proper sun protection.
