What is the difference between V-face lifting needle and slimming needle

The main difference between V-face lifting needle and slimming needle lies in their different principles of action and indications. The V-face lifting needle achieves contour tightening by stimulating collagen regeneration, while the slimming needle achieves the effect of slimming the masseter muscle by blocking nerve and muscle contraction. There are differences between the two in terms of ingredients, applicable parts, maintenance time, onset speed, and risk of side effects.

I. Composition Differences

The main components of the V-face lifting needle are biological stimulants such as polylactic acid or hyaluronic acid, which promote collagen proliferation by activating fibroblasts. Facial slimming needles are mostly made of type A botulinum toxin, which can selectively paralyze motor nerve endings. The former belongs to volume filling preparations, while the latter is a neuromodulatory drug.

II. Mechanism of Action

The V-face lifting needle forms a collagen fiber network in subcutaneous tissue, improving skin laxity and sagging, and is suitable for patients with blurred mandibular margins. The facial slimming needle acts on the end plate of the masseter muscle movement, inhibiting excessive muscle contraction, and has a significant effect on the square face shape caused by masseter muscle hypertrophy. The former requires multiple injections to establish cumulative effects, while the latter can be effective with a single injection.

3. Applicable areas

V-face lifting needles are mostly used in the middle and lower facial regions, such as the jawline, apple muscles, nasolabial folds, and other areas of aging relaxation. The slimming needle is only suitable for the masseter muscle area, and the injection point is located in the area between the earlobe and the corner of the mouth. Incorrect injection may lead to stiff facial expressions or difficulty swallowing, and strict differentiation of treatment targets is necessary.

Fourth, Time Comparison

The effect of the V-face lifting needle usually gradually appears within 3-6 months and can be maintained for up to 18-24 months. The facial slimming needle starts to show efficacy after 2 weeks, reaches its peak within 1-3 months, and requires repeated injections to maintain for 4-6 months. The former has a delayed and long-lasting characteristic, while the latter requires regular replenishment to maintain its effectiveness.

V. Risk Differences

V-face lifting needles may cause nodules, swelling, or allergic reactions, while slimming needles often have side effects such as temporary chewing weakness and asymmetrical smiles. Both should be avoided during pregnancy and lactation, and are contraindicated for those with coagulation dysfunction. The V-face lift has higher aesthetic requirements for operators, and the slimming needle tests the accuracy of anatomical positioning.

When selecting, it is necessary to consider the basic facial conditions and improvement needs. Priority should be given to facial slimming injections for masseter hypertrophy, while V-face lifting injections are suitable for sagging and loose skin. professional evaluation should be conducted before surgery to avoid the potential burden of simultaneous use. After treatment, pay attention to avoiding local pressure, high temperature environment, and vigorous exercise. If there is persistent redness, swelling, and pain, timely follow-up is necessary. Combining daily lifting massage and sun protection care can help prolong the effect.
