Comprehensive Botox Aesthetics

Refine facial balance by relaxing overactive muscles to lift, slim, and smooth areas from forehead lines to jaw tension. Beyond wrinkle care, Botox also eases tension headaches and teeth grinding, and can create slimmer, more elongated legs by relaxing bulky calf muscles.

Platelet-Rich Plasma (PRP) Therapy

On the face, PRP boosts collagen production, smooths fine lines, improves texture, and restores a healthy glow. On the scalp, it strengthens hair follicles, reduces shedding, and encourages new hair growth.
