What causes dynamic wrinkles? Effective solutions for improvement

Dynamic wrinkles typically appear on the forehead, between the eyebrows, and around the corners of the eyes—areas that become especially prone to them as the skin begins to age. How do these dynamic wrinkles form, how do they differ from static wrinkles, and what effective methods can help diminish them? Join HBIO Clinic as we explore these questions to help you choose the right skincare approach.

What are dynamic wrinkles?

Dynamic wrinkles (expression lines) are temporary creases that appear when facial muscles move to express emotions.

Unlike fixed creases (static wrinkles), dynamic wrinkles disappear when the facial muscles relax. Over time, and as a result of aging, dynamic wrinkles can deepen and become static wrinkles.

Common areas prone to dynamic wrinkles

Areas with high frequency of muscle contraction are typically the most prone to developing expression lines:

• Forehead: Horizontal lines appear whenever you raise your eyebrows, directly linked to the contraction of the frontalis muscle.
• Outer corners of the eyes: Crow’s feet emerge when squinting or laughing heartily, caused by the movement of the orbicularis oculi muscle.
• Between the eyebrows: Vertical folds appear when frowning, resulting from the activity of the corrugator supercilii and depressor supercilii muscles.
• Nose area: “Bunny lines” appear on the sides of the bridge of the nose when wrinkling the nose or smiling broadly, influenced by the nasalis and levator labii superioris muscles.
• Corners of the mouth: Folds or creases appear during speaking or smiling, caused by the movement of the orbicularis oris and the muscles that lift the corners of the mouth.
• Around the lips: Tiny vertical lines form due to the habit of pursing the lips or the repetitive movement of the orbicularis oris muscle.

The origin of dynamic wrinkles

Temporary folds form due to repetitive muscle contractions. This condition becomes increasingly pronounced as a result of the following factors:

• Deficiency in collagen and elastin: As aging reduces skin elasticity, the skin struggles to return to a smooth, flat state after each movement.
• Thinning and dehydration: The loss of natural moisture, combined with a thinning skin surface, makes folds more prone to becoming deep-set.
• Sun damage: UV rays destroy the supportive fiber network within the dermis, causing the skin to sag prematurely and develop wrinkles.
• Habitual, exaggerated facial expressions: Frequent frowning, raising the eyebrows, or laughing heartily places continuous muscular pressure on the skin’s structure.
• An unhealthy lifestyle: Mental stress, lack of sleep, tobacco use, and a nutrient-poor diet accelerate the aging process.

Effective treatment methods for dynamic wrinkles

To soften expression lines and prevent them from deepening into permanent wrinkles, modern aesthetic treatments focus on relaxing facial muscles while simultaneously restoring the skin’s underlying structure. Depending on your specific needs, you may consider the following optimal solutions:

Botox

This is considered the fastest and most effective method for addressing dynamic wrinkles. The active ingredient helps to soothe and relax overactive, contracting muscles, thereby smoothing the skin’s surface when you make facial expressions.

Results become visible after approximately 5–7 days and typically last for 3–6 months.

• Estimated cost: 1,200,000 VND – 14,000,000 VND per treatment area.
• Pros: Rapidly smooths out expression-related wrinkles; the procedure is quick and requires no downtime.
• Cons: Effects only last 3–6 months, and the procedure requires a high level of skill to avoid a “frozen” or stiff facial appearance.

HA, Meso, PRP, Exosome

• Hyaluronic Acid (HA) / Skinbooster: Provides immediate hydration, plumping the skin and softening fine lines.
• PRP & Exosome: Delivers growth factors into the dermis, supporting cellular repair, enhancing elasticity, and strengthening the skin’s underlying structure from within.

Estimated cost: 2,500,000 VND – 12,000,000 VND per session.

Pros: Deeply hydrates, leaves the skin looking plump, radiant, and smooth; highly safe and gentle.

Cons: Requires a series of sessions; effective only for softening mild, superficial wrinkles.

Biostimulator

This method utilizes safe, biocompatible compounds (such as PLLA, PDLLA, or PCL) to stimulate the body’s own production of endogenous collagen. It enhances skin thickness and firmness, resulting in a softer, more natural appearance for expression lines.

• Estimated cost: 6,000,000 VND – 22,000,000 VND per treatment course.
• Advantages: Stimulates the skin to produce its own collagen, strengthens the skin’s foundation, and offers long-lasting results (1–2 years).
• Disadvantages: Relatively high cost; results appear gradually over 1–2 months rather than being immediately visible.

Laser, RF, HIFU

• Fractional CO2 / Er:YAG Laser: Resurfaces the skin by removing aged, keratinized cell layers and stimulating cell renewal.
• Radiofrequency (RF & Microneedle RF): Delivers thermal energy into deeper skin layers, causing collagen fibers to contract and firming the skin tissue.
• High-Intensity Focused Ultrasound (HIFU): Targets deep layers, including the dermis and the superficial musculoaponeurotic system (SMAS), to provide a lifting effect and address skin laxity.

Estimated cost: 2,000,000 VND – 45,000,000 VND per treatment course.

Advantages: Deep-acting treatments that provide comprehensive skin lifting and firming without the need for surgery.

Disadvantages: High cost; some procedures may require a few days for skin redness to subside following treatment.
