Body Filler Guide: Areas, Dosage, Cycles & Care

They differ in formulation, crosslinking density, structural support, and intended treatment areas — they are not interchangeable.

Charmost® Body Filler is a highly crosslinked, large-particle, high-viscosity hyaluronic acid gel. Its dense gel structure provides strong structural support, low migration rate, and slow metabolic degradation. It is specifically engineered for large-volume body contour correction.

Facial HA fillers (including skin boosters and fine facial fillers) have a softer texture and weaker support. They cannot meet the demands of large-area body contouring, and if used on the body, they are prone to collapse and short duration.

It is used to optimize body contours and fill depressions for smoother, more flowing body lines. Common treatment areas include:

• Buttock shaping and hip dip correction
• Thigh transition zone contouring
• Shoulder line enhancement
• Hand rejuvenation
• Minor breast refinement

It can address flat buttocks, hip dips, narrow shoulder lines, discontinuous contours, and soft tissue depressions. As a non-surgical contouring solution, it offers short downtime and flexible customization.

Compared to surgical implants and autologous fat grafting, Charmost® HA body filler offers clear advantages:

• No surgery — tiny needle entry points, minimal bleeding
• Immediate visible results with a natural, soft feel
• Precise dosage control for fine adjustments and to avoid over-correction
• Excellent biocompatibility — fully degradable by the body
• Reversible — if results are unsatisfactory, hyaluronidase can be injected for correction

Charmost® Body Filler follows the principle of "small amounts, multiple sessions, gradual and conservative dosing". Dosage is determined by the degree of depression, body baseline, and aesthetic goals, with per-session limits set to reduce the risk of swelling, migration, and nodules.

Charmost® Body Filler is a contour-maintenance treatment, not a frequent hydration procedure.

• Single session: Results are visible immediately after injection. Mild swelling subsides within 7–15 days, revealing the final natural contour.
• Full contouring course: For large-area shaping (buttocks / hip dips), 2 sessions spaced 3–4 weeks apart are recommended. Gradual incremental filling produces smoother, more stable contours.
• Duration: Typically 12–24 months. Shoulder line results last around 12–18 months; the buttock area lasts longer. People with faster metabolism, high-intensity training, or frequent weight changes may experience faster degradation.
• Touch-up recommendation: After the initial contouring course, a touch-up at 10–12 months helps maintain the contour.

The standard approach is deep tunnel injection combined with layered layering. The needle is placed in the deep subcutaneous soft tissue layer, not the superficial dermis. Charmost® gel must be distributed evenly in layers to avoid nodules, bulges, and migration — achieving natural body lines.

Proper pre-treatment preparation reduces the risk of bruising, swelling, and infection while improving filler stability:

• 1 week before: Discontinue aspirin, anticoagulant supplements, and high-concentration acid or retinol body skincare products to avoid prolonged bleeding and skin sensitivity. Avoid prolonged sun exposure.
• 3 days before: Keep the body skin intact. Avoid body exfoliation, deep massage, or heat therapy to protect the skin barrier.
• On treatment day: Thoroughly cleanse the skin. Do not apply body lotion or oils. Avoid treatment during menstruation or when physically fatigued.
• Pre-treatment consultation: Clarify aesthetic expectations, confirm product compliance, and customize the dosage plan based on individual body conditions.

The following groups should avoid or postpone treatment:

• Pregnant and breastfeeding women
• Patients with autoimmune diseases or coagulation disorders
• Those with active inflammation, open wounds, or fungal infections at the treatment site
• Anyone allergic to hyaluronic acid
• Patients with severe skin laxity requiring surgical lifting

The first 14 days are the critical period for filler stabilization. Core principles: avoid pressure, prevent migration, stay away from heat, and no intense exercise.

• First 24 hours: Do not get the treated area wet, and do not touch, press, or massage it. No ice or hot compresses — they can cause gel displacement and nodule formation.
• Within 7 days: No sauna, steam room, hot baths, or intense sun exposure. Avoid tight, compressive clothing that could distort the contour.
• Within 14 days: No high-intensity gym training or strength training. Buttock filler patients should minimize sitting time and use a pressure-relief cushion to prevent Charmost® filler displacement and accelerated absorption.
• Dietary restrictions: Avoid alcohol, smoking, spicy foods, and seafood for 1 week to reduce inflammation and speed recovery.

Yes — these are common transient tissue reactions. Mild swelling and localized firmness are normal signs of tissue adapting to the filler. Swelling subsides in 3–7 days, and firmness gradually softens within 1–2 weeks as the filler integrates with the tissue. Bruising typically resolves in about a week.

If you experience persistent severe pain, localized warmth, or pus, seek immediate follow-up care.

• Daily activities and loose clothing: Can resume 24 hours after treatment.
• Body cleansing and basic moisturizing: Can resume 3 days after treatment once needle points are fully closed.
• Light activity (walking, gentle yoga): Can resume 2 weeks after treatment.
• Heavy weight training and prolonged pressure on the treated area: Wait at least 4 weeks until Charmost® filler is fully stabilized.

No. Over-injection is the greatest risk with body fillers. Excessive Charmost® gel can lead to unnatural contours, persistent swelling, surface irregularities, and migration. Gradual, staged filling produces smoother lines and more stable results.

No. Rubbing, squeezing, or massaging the injection site is strictly prohibited for 14 days. Before the filler is fully set, external pressure can displace Charmost® gel, causing asymmetry or uneven contours. Any adjustments must be performed by a qualified professional.

No. Charmost® Body Filler is a degradable hyaluronic acid that is gradually broken down by the body's metabolism. It is a long-lasting, reversible aesthetic solution. Compared to facial fillers, Charmost® body filler has higher crosslink density and larger single-use volume, so it lasts longer. Regular touch-ups maintain the ideal contour.
