Once you reach your 40s, have you ever glanced in the mirror and thought, “My jawline looks blurry,” “My cheeks seem to be drooping,” or “My nasolabial folds have deepened”?
That may be a sign of sagging. Sagging after your 40s is heavily influenced by age-related changes in the body as well as lifestyle habits.
This time, we’ll explain the causes of sagging and how to improve it in an easy-to-understand way.

Sagging is mainly caused by the loss of skin elasticity and support due to aging. Specifically, the following factors are involved.
Collagen and elastin are important components that maintain skin firmness and elasticity. After your 40s, these decrease, causing the skin to lose its support and sag.
As you age, the fat in your cheeks and jawline can no longer resist gravity and shifts downward. This is what causes nasolabial folds and marionette lines (sagging around the mouth) to become more noticeable.
Did you know that the bones in your face actually shrink with age? In particular, when the cheekbones and jawbone decrease in size, the skin and muscles lose their support, making sagging more pronounced.
When the facial muscles that support the face weaken, the skin becomes more prone to drooping. In particular, weakened muscles around the cheeks and jaw can throw off the jawline.
Besides age, daily habits such as UV exposure, lack of sleep, an unbalanced diet, and stress also accelerate sagging. These are factors that speed up skin aging.
If left untreated, sagging will progress, but with the right care, improvement is possible. Here are some care methods worth incorporating after your 40s.
Skincare is the foundation of improving sagging. Using items that contain the following ingredients is effective.
①Retinol: Promotes collagen production.
②Vitamin C Derivatives: Maintains skin firmness and supports elasticity.
③Ceramides: Boosts the skin’s moisture-retaining ability and prevents sagging caused by dryness.
In addition, it’s also recommended to use a cream with a lifting effect and massage upward from the bottom.
Just like the muscles in your body, facial muscles become firmer when trained. Try doing the following simple exercises every day.
The “A-I-U-E-O” Exercise: By moving your mouth widely as you say each sound, you can train the muscles of your entire face.
Tongue Rolling Exercise: Rolling your tongue widely inside your mouth is expected to help tighten the nasolabial folds and jawline.
By improving your daily habits, you can prevent and improve sagging.
UV Protection: Apply sunscreen every day.
Sufficient Sleep: Get proper sleep during the hours when skin regeneration is most active (10 PM to 2 AM).
A Balanced Diet: Actively consume vitamin C (citrus fruits, broccoli), vitamin E (nuts, pumpkin), and protein (fish, soy products).
If self-care alone doesn’t feel like enough, turning to beauty devices or medical treatments is also an option.
Home Beauty Devices: EMS (electrical muscle stimulation) or ultrasound can help train the muscles and promote lifting.
〜Aesthetic Medicine〜
HIFU (High-Intensity Focused Ultrasound): A lifting treatment that lifts sagging skin.
Thermage and Volnewmer: The pinnacle of RF (radiofrequency) treatments. Treatments that provide firm lifting with low risk.
Hyaluronic Acid Injections: Restores volume and makes sagging less noticeable.
Sylfirm X: In CW mode, it promotes collagen and new skin generation, helping prevent both sagging and wrinkles.
High-Dose Vitamin C IV Drip: Since good-quality vitamin C is essential for boosting collagen production, taking it in properly helps prevent the oxidation that causes sagging, slowing its progression.
NMN IV Drip: Activates cells to boost metabolism, leading to an overall rejuvenating effect on the body.
Sagging is a natural phenomenon that comes with aging, but by continuing appropriate care, it’s possible to slow its progression or even improve it.
From your 40s onward, review your daily skincare and lifestyle habits, and take countermeasures against sagging in a way that suits you.
By facing “sagging” head-on, you can keep not only your appearance but also your mind feeling youthful.
