Methods & devices — how they work, the procedure, who should not have them
Each method explains the mechanism, procedure, risks and who it is not suitable for — so you understand before you decide.
Aesthetic Medicine
BAP (Bio Aesthetic Points) Technique with Skin-Restructuring HA: 5 Points per Side of the Face, Mechanism of Action, and Ideal Candidates
BAP technique involves injecting high-concentration, thermally cross-linked (chemical-free) HA into 5 anatomical points on each side of the face to diffuse and stimulate collagen and elastin across a broad area. It improves skin firmness, elasticity, and overall quality without altering facial contours.
Mesotherapy (Micro-injections of Active Ingredients): Mechanism of Action, Common Ingredients, Treatment Protocol, and Limitations
Mesotherapy delivers a blend of nutrients (non-cross-linked HA, vitamins, minerals, amino acids, and peptides) into the superficial layer of the skin via micro-injections to improve hydration, radiance, and skin texture. Results are cumulative over a course of treatment.
Skin Booster (Hyaluronic Acid Hydration Injections): Mechanism, Differences from Dermal Fillers and Mesotherapy, Treatment Protocol, and Ideal Candidates
Skin boosters consist of fluid, minimally cross-linked hyaluronic acid (HA) micro-injected into the dermis to deeply hydrate from within and mildly stimulate collagen production. They do not add volume; instead, they improve skin smoothness, radiance, fine lines, and dehydration.
HA Dermal Fillers: Mechanism of Action, Treatment Areas, G-Prime Selection, Vascular Safety, and Hyaluronidase
HA fillers are cross-linked hyaluronic acid gels injected into the skin or onto the bone to restore volume, contour features (chin, nose, cheeks, lips), and smooth static lines. They naturally dissolve over 6–18 months and can be reversed with a dissolving agent if needed.
Botulinum toxin (Botox): Mechanism of Action, Treatment Areas, Personalized Dosages, Risks, and Contraindications
Botulinum toxin selectively relaxes the muscles responsible for dynamic wrinkles (forehead lines, frown lines, crow's feet) or overactive muscles (masseter and chin muscles). Results appear within 5–14 days and last for 3–4 months.
Non-invasive HIFU skin lifting: mechanism, actual efficacy, and suitable candidates
HIFU delivers focused ultrasound energy into the SMAS and deep dermis, creating thermal coagulation points that stimulate collagen contraction and regeneration—improving firmness for mild-to-moderate skin laxity with no downtime; results are moderate and require maintenance treatments.
Laser toning (Pastelle Q-switched Nd:YAG): Treats melasma, dark spots, freckles, and evens skin tone
The Q-switched Nd:YAG laser delivers ultra-short pulses to break down pigment particles in the skin. In low-energy, multi-session toning mode, it lightens melasma and deep hyperpigmentation; at higher energy settings, it clears freckles and brown spots after a few sessions.
PRP (Platelet-Rich Plasma): The Supportive Role in Acne Scar Treatment and Skin Recovery
PRP is derived from your own blood and contains growth factors that support wound healing. In atrophic scar treatment, PRP serves as an add-on step following microneedling, laser, or subcision—not a stand-alone scar-filling procedure.
Acne Treatment
Medical-grade acne extraction: how it differs from spa extractions, the sterilization process, and which types of acne should not be extracted.
Extracting comedones and 'ripe' acne in a sterile environment, using the correct tools and appropriate pressure — to enhance medication absorption and reduce post-inflammatory hyperpigmentation. Deep inflammatory acne, cystic acne, and nodules should not be squeezed.
Chemical Peels for Acne, Hyperpigmentation, and Dull Skin: Acid Types, Peel Depths, Procedure, and Contraindications
Chemical peels utilize acids at controlled concentrations and pH levels to remove dead skin cells and stimulate skin renewal: salicylic acid for acne and oily skin, glycolic acid for dull skin, and low-concentration TCA for dark spots and skin texture. The depth of the peel determines its efficacy and downtime.
Subcision: Releasing Fibrous Bands for Rolling Acne Scars
Subcision uses a specialized needle inserted beneath the skin to release the fibrous bands tethering the scar base down—a core step for rolling scars, often combined with laser or microneedling to smooth the skin surface afterward.
TCA CROSS for Atrophic Scar Treatment: Deep Focal Technique for Ice Pick Scars
TCA CROSS delivers high-concentration acid directly to the base of each scar to stimulate regeneration from the bottom up—a technique specifically used for deep ice-pick and boxcar scars that surface lasers cannot reach.
Microneedling: How Effective Is It for Atrophic Acne Scars and When Is It Not Enough?
Microneedling creates thousands of micro-injuries to stimulate natural collagen production—minimally invasive, offering fast recovery, and ideal for shallow pitted scars and rough skin texture. For deeper scars, microneedling alone is often insufficient and requires combination treatments.
RF Microneedling for Scar Treatment and Skin Tightening: How It Differs from Traditional Microneedling
RF microneedling delivers radiofrequency energy through micro-needles deep into the dermal layer, stimulating collagen production with minimal surface disruption—making it ideal for deep pitted scars, thick skin, hyperpigmentation-prone skin, and enlarged pores.
Fractional CO2 Laser for Atrophic Acne Scars: Mechanism, Procedure, Indications, and Contraindications
Fractional CO2 laser creates thousands of controlled micro-injuries to stimulate the skin's natural collagen regeneration, elevating the base of pitted scars. It is effective for shallow to moderate boxcar and rolling scars; multiple sessions and strict sun protection are required.
Rhinoplasty
Autologous Costal Cartilage Rhinoplasty: Indications, Pros, Cons, and the Cartilage Harvesting Procedure
Costal cartilage provides sufficient volume and structural rigidity to reconstruct the nasal framework in complex cases: revision rhinoplasty, contracted/short noses, and cases requiring significant nasal lengthening. It is not the default choice for simple, primary rhinoplasty.
Nasal Wing Reduction (Alar Plasty): Techniques, Who Needs It, Incision Locations, and Risks of Asymmetrical Nostrils
Nasal wing reduction involves removing excess skin and soft tissue at the base of the nostrils or the nasal floor to create a slimmer appearance and balanced nostrils. This is a minor procedure, but it can be challenging to correct if too much is removed — the principle is to cut just enough.
Revision Rhinoplasty (Secondary Rhinoplasty): When It Is Needed, Why It Is More Challenging, and the Procedure at BonBoz
Revision rhinoplasty addresses complications from previous nose surgeries, such as deviation, visible implants, redness, contracture, infection, or unsatisfactory aesthetic results. The procedure is more complex than primary surgery due to scar tissue, thinned soft tissue, and previously used autologous cartilage.
Comprehensive structural rhinoplasty: reconstructing the nasal framework using autologous cartilage — for complex cases and revision rhinoplasty
Total structural rhinoplasty reconstructs the osteocartilaginous framework using autologous cartilage (septal, auricular, or rib cartilage): lengthening short noses, projecting bulbous tips, and correcting failed previous surgeries. The procedure takes longer and requires an extended recovery period along with an experienced surgeon—in return, it successfully resolves complex cases that other techniques cannot achieve.
Semi-Structural Rhinoplasty: Bridge Augmentation + Tip Reshaping, Preserving the Native Framework — When Is It the Right Choice?
Semi-structural rhinoplasty elevates the nasal bridge with synthetic implants, reconstructs the columella, and reshapes the nasal tip using autologous cartilage while preserving the native nasal framework—bridging the gap between cartilage-grafted and full structural rhinoplasty in terms of invasiveness, recovery time, and cost.
Cartilage-grafted rhinoplasty: synthetic implant + autologous cartilage tip graft — suitable candidates and limitations
Dorsal augmentation using synthetic implants combined with tip graft coverage using ear cartilage (or Megaderm) prevents excessive tension on the nasal tip skin—a popular technique for low nasal bridges with a relatively well-defined tip and moderate skin thickness. This method cannot correct a bulbous or severely short, upturned tip.
