TEOSYAL® DEEP LINES

Product Overview: TEOSYAL® DEEP LINES

TEOSYAL® DEEP LINES is an injectable, non-pyrogenic, transparent viscoelastic gel composed of reticulated (cross-linked) hyaluronic acid (HA) of non-animal origin. Manufactured by Teoxane Laboratories (Geneva, Switzerland), this formulation is specifically developed for injection into the deep dermal layer to address significant facial wrinkles and folds.

It is indicated for correcting pronounced lines, such as deep nasolabial folds and marionette lines, and may be suitable for certain facial contouring applications where deep dermal support is needed.

Note: This medical device is intended for administration solely by licensed medical professionals trained and experienced in dermal filler injection techniques.

Mechanism of Action and Properties

TEOSYAL® DEEP LINES functions by providing volume and structural support upon injection into the deep dermis. The cross-linked hyaluronic acid gel physically fills and lifts deep wrinkles and folds from beneath. Its rheological properties are designed to offer sufficient firmness and cohesivity to effectively correct deeper skin depressions while integrating into the dermal tissue. The hydrophilic nature of hyaluronic acid also helps to attract and retain water, contributing to localized skin hydration and turgor.

The degree of cross-linking is designed to provide a durable clinical effect, typically lasting several months. However, individual results and longevity vary based on patient factors (age, skin type, metabolism), treatment area, injection volume, and practitioner technique.

This formulation does not contain integrated lidocaine; practitioners should consider appropriate anesthetic methods to manage patient comfort during the procedure.

Indications and Usage

TEOSYAL® DEEP LINES is indicated for the correction of deep facial wrinkles and folds, including:

• Deep nasolabial folds (smile lines)
• Pronounced marionette lines
• Other significant facial creases requiring deep dermal correction
• May be considered for augmentation or contouring in areas like the cheeks where deep dermal support is appropriate (practitioner assessment required)

Injection should be performed into the deep dermis by qualified practitioners using correct techniques and aseptic protocols. Suitability for lip augmentation is generally less ideal compared to dedicated lip products due to its properties.

Expected Outcomes

Professional application aims to deliver:

• Significant smoothing and correction of deep facial wrinkles and folds
• Restoration of volume and support within the deep dermis
• Improved facial contours in treated areas
• Enhanced skin structure and firmness locally

Potential Adverse Events

Practitioners must thoroughly discuss potential side effects with patients before treatment. Possible adverse events include:

• Common Reactions (Typically Mild and Transient): Injection site reactions such as swelling, bruising, erythema (redness), pain, tenderness, itching, or palpable firmness/lumps. These generally resolve within several days to a week.
• Less Common/Rare but Serious Reactions: Prolonged swelling or induration; significant hematoma; infection; inflammatory reactions (sometimes delayed); hypersensitivity/allergic reactions; formation of persistent nodules or granulomas; skin discoloration; abscess formation; contour irregularities; vascular complications (rare but serious, including potential necrosis or embolism if accidentally injected into a blood vessel); temporary nerve effects.

Comprehensive knowledge of facial anatomy, safe injection techniques, and management of potential complications is crucial. Patients should report any severe, persistent, or concerning reactions immediately.

Storage Conditions

Store between 2°C and 25°C. Protect from freezing temperatures and direct sunlight. Verify package integrity before use.
