Swelling after Kybella® is actually a positive sign—it indicates that the deoxycholic acid is actively breaking down and destroying targeted fat cell membranes. Following these essential post-care guidelines will ease temporary tenderness, manage the inflammatory response, and ensure you achieve the crispest, most defined profile.
Tenderness, Warmth & Redness: The submental area will feel warm, tender, and firm to the touch for several days following injections as tissue inflammation occurs.
Temporary Numbness & Firmness: A gel-like firmness, mild hardness (nodules), or surface numbness under the chin is common and resolves gradually over 2 to 6 weeks as the body clears fat debris.
Mild Bruising & Pinpoint Marks: Mild bruising or small red puncture marks from the grid injection pattern are normal and clear within 5 to 10 days.
Apply Cold Packs (First 24 Hours): Apply an ice pack wrapped in a cloth to the submental area for 10–15 minutes at a time during the first 24 hours to soothe heat and ease excessive swelling.
Apply Alastin INhance Serum: Gently apply Alastin INhance Post-Injection Serum twice daily to accelerate bruise resolution and support tissue recovery.
Elevate Head & Avoid Strenuous Exercise: Sleep with your head elevated on 2 pillows for the first 2–3 nights. Avoid vigorous exercise, saunas, and intense heat for 48 hours to minimize extra swelling.
Maintain Treatment Roadmap: Kybella® typically requires a series of 2 to 4 sessions spaced 6 to 8 weeks apart. Do not delay booking your next assessment to keep your results progressing.
Deoxycholic acid actively disrupts fat cell membranes. Submental swelling peaks within 48 hours; ice packs, head elevation, and soft clothing help ease comfort.
Visible swelling and bruising diminish significantly. The submental area may feel slightly firm, gel-like, or numb as your body clears cellular debris.
Fat clearance is complete, revealing a visibly slimmer submental contour. At week 6–8, you return for your follow-up assessment and optional second session.
Once your full series (2–4 sessions) is completed, destroyed submental fat cells cannot regenerate, providing permanent profile alteration.
Dissolving submental fat creates the foundation for a refined lower face. Frame your newly contoured jawline with complementary structural dermal fillers, neck skin tightening, and clinical home care.
Once submental swelling resolves (around week 4–6), enhance your lower face profile with structural dermal contouring and skin firming:
Benefits: As Kybella removes fullness beneath the chin, structural hyaluronic acid filler along the jawline and chin apex creates a sharp, distinct angle separating the face from the neck.
