BBL Scars: Where the Incisions Actually Go

Every BBL involves 5–10 small access ports for lipo harvest and fat injection. Where they sit determines how visible your scars are long-term. Here's the typical incision map, how surgeons plan for concealment, and what scar care actually helps.

Safety standard: Every article on this site assumes fat grafting is performed subcutaneously only — never into or beneath the gluteal muscle. Intramuscular fat injection carries a fatal fat-embolism risk documented across surgical literature and is the reason for the current international consensus on subcutaneous-only technique, ideally with real-time ultrasound guidance. Colombia's accredited plastic surgeons follow this standard.

Most patients coming for BBL consultations focus on shape, volume, and recovery — and almost none ask about scars until they see photos of their own body six months post-op. The reality is that a BBL involves multiple small incisions ("access ports") both for the liposuction harvest and for the fat injection. Where those ports sit determines how visible the scars are in clothing, bathing suits, and daily life.

This piece walks through the typical port pattern in a Colombian BBL, how experienced surgeons plan their placement for scar concealment, and what scar care actually helps versus what's marketing.

The typical incision map

A modern BBL involves 5–10 small access incisions, each about 3–5mm — smaller than a grain of rice. They're placed at three main location categories:

LocationFunctionTypical concealment
Upper flanks / lower backLipo harvest of upper flanks and back rollsJust above bikini line — hidden in swimwear
Lower back / sacral dimpleLipo harvest of lower back and BBL injection portSits at sacral dimple — visible only in low-back cuts
Upper buttock (bilateral)BBL injection portsHigh on upper buttock — hidden in most underwear
Abdominal (upper & lower)Lipo harvest of abdomenUmbilicus + lower abdomen — mostly hidden by underwear
Inner thighs (optional)Lipo harvest for inner thigh sculptingGroin fold — hidden in daily wear
Total port count depends on how many zones are lipo'd and how many injection ports the surgeon uses.

Why port placement matters

Two surgeons doing "the same BBL" can produce very different long-term scar visibility based on:

What BBL scars actually look like

At maturity (typically 12+ months), BBL scars in most patients are:

Skin type Fitzpatrick IV–VI (many Latin American, African, and Asian patients) is more prone to post-inflammatory hyperpigmentation — scars that heal darker than surrounding skin. This is manageable with scar care but should be discussed at consult.

Keloid formers need a separate conversation

Patients with a history of keloid scarring (raised, expanding scars that grow beyond the original incision) need to disclose this at consult. Keloids can form at BBL port sites — visible as raised bumps that don't flatten over time. Colombian surgeons who see this on the exam or history may recommend adjunctive treatments (intra-op steroid injection, post-op laser) or in some cases decline the procedure.

Scar care during recovery

Evidence-supported approaches:

Weeks 1–4: healing phase

Weeks 4–12: remodeling

Months 3–12: maturation

What doesn't help

Common myths that aren't supported by evidence:

The port scar you'll notice most

The single scar most patients notice long-term is the sacral dimple port — a small mark right at the base of the spine that some surgeons use for both lipo harvest and BBL injection. It's centered and visible in low-back cuts (bathing suits, lingerie). Some surgeons deliberately place a different port pattern to avoid this scar in patients concerned about it. Ask specifically at consult.

Timeline for BBL port scar maturation
Individual variation is significant — dark-skinned patients typically see longer maturation times.
Ports closed / initial healing 2 weeks Silicone therapy started 3 weeks Peak scar prominence (weeks) 6 weeks Substantial scar fading (weeks) 24 weeks Mature scar appearance (weeks) 52 weeks
Peak prominence is often around 6 weeks when the body's remodeling response is most active.

Consult questions about scars specifically

A surgeon confident in their scar outcomes will readily show 12-month photos. A surgeon showing only 3-month photos may be hiding maturation issues that come later.
