If your neck is starting to sag, don’t ignore it. This is why it happens

Loss of Collagen and Elastin
As you age, your skin produces less collagen (for firmness) and elastin (for elasticity). This leads to looser, thinner skin that begins to droop.
Gravity & Skin Laxity
Gravity constantly pulls on the skin, and over the years, it starts to show—especially in areas like the neck where the skin is thinner and more delicate.
Muscle Weakness (Platysma Banding)
The platysma muscle, which runs from your jawline to your collarbone, becomes looser with age. This can cause visible vertical bands and sagging under the chin.
Fat Accumulation or Loss
You may develop a “turkey neck” from fat collecting under the chin, or from fat loss that makes the skin look hollow and droopy.
Sun Damage (Photoaging)
UV rays break down collagen and elastin faster than aging alone. If you haven’t been using sunscreen on your neck (most people forget!), it can age faster than your face.
Poor Posture (Tech Neck)
Constantly looking down at phones or screens can cause wrinkles and skin laxity from repeated creasing and lack of muscle engagement.

Topical Retinoids (Retinol, Tretinoin): Stimulate collagen production.
Peptides & Growth Factors: Can improve skin elasticity over time.
Firming Creams: These can help slightly, especially those with hyaluronic acid, caffeine, or niacinamide.
Neck Exercises: May mildly strengthen underlying muscles.

Ultrasound or Radiofrequency (e.g., Ultherapy, Thermage): Non-invasive tightening.
Microneedling + RF (e.g., Morpheus8): Stimulates deep collagen remodeling.
Laser Resurfacing: Improves texture and tightness.

Use sunscreen daily on your neck.
Moisturize your neck regularly.
Maintain good posture.
Avoid yo-yo dieting (which can affect skin elasticity).
Stay hydrated and eat skin-supportive foods (rich in vitamin C, antioxidants, omega-3s).
