Brazilian laser hair removal treats the hair of the pubic region, labia and perianal area with a long-pulsed laser so that regrowth is reduced over a staged course. The skin here is usually darker than the rest of the body and the hair is coarse, so wavelength and cooling matter more than anywhere else. Dr Sin Yong agrees the extent beforehand, and every session is doctor-performed with a chaperone offered.
Short answerA brazilian covers the whole pubic region, including the labia and the perianal area, as opposed to a bikini line, which clears only the edges. The extent is agreed before treatment. The skin is often a shade deeper than elsewhere, which usually moves the choice toward 1064 nm Nd:YAG, or conservative 755 nm settings on lighter skin, with close attention to cooling.

Privacy
Treatment in a private room, draping of everything not being treated, a chaperone offered, and the option to stop at any point
Wavelength
The skin here is often darker than the rest of the body, so 1064 nm Nd:YAG is the usual choice; 755 nm alexandrite at conservative settings on lighter skin
Ingrown hairs
Waxing and shaving drive ingrown hairs and folliculitis in this area; inflamed skin is settled before any pulse
Preparation
Shave the area; do not wax or pluck beforehand; declare pregnancy, recent isotretinoin, photosensitising medicines and any genital herpes history
Men
The equivalent area is assessed on the same principles; skin tone and hair characteristics decide the wavelength, not the name of the area
What a brazilian includes, and how it differs from a bikini line
The names are used loosely, so the first thing done at consultation is to agree what will be treated. A bikini line clears hair beyond the edge of ordinary underwear or swimwear: the top of the thighs and the lower abdomen, leaving the pubic region itself alone. An extended bikini takes a little more from the sides and the top. A brazilian treats the pubic region as a whole: the mons pubis, the labia majora, the perineum and the perianal area, either completely or leaving a strip or triangle at the front. A full brazilian, sometimes called a hollywood, leaves nothing.

Each of these is a different amount of skin, in different conditions. The mons and the upper thigh are ordinary body skin, often tanned at the edges. The labia majora and perineum are thinner, more pigmented, and have been shaved or waxed for years in most people who ask. The perianal area is the most pigmented and the most sensitive to heat. Because tone varies within the area, the skin is examined in each part and the settings follow the darkest part being treated, not the lightest. The principles common to every area are on the main laser hair removal page.
Dr Sin Yong draws the agreed boundary with you before the first visit and keeps the same map at each one. Changing the extent later is straightforward; starting with an area that was not discussed is not something that happens here.
Privacy, chaperoning and how the session is conducted
This is an intimate area, and the practical arrangements are worth setting out plainly so that nobody is left guessing. Treatment takes place in a private room with the door closed. Disposable underwear or draping is used so that only the part being treated is uncovered, and the drape is moved section by section rather than removed. Protective eyewear is worn throughout, by you and by the doctor.
A chaperone is offered for every intimate treatment and is present whenever you want one; you can also bring someone. Singapore Medical Council guidance treats a chaperone as good practice for intimate examinations, and it is offered here as a matter of routine rather than only on request. The chaperone is a member of the clinic team, and their only role is to be present. You can stop the session at any point, for any reason, and the area is covered while you decide. Nothing is photographed.
What the session itself involves
The skin is checked in each part of the area for shaving rash, ingrown hairs, folliculitis, broken skin, moles and any lesion that needs a look before a pulse is delivered
The agreed boundary is confirmed, and the position used is the one that flattens the skin being treated; the perianal area is treated last, lying on the side
Each pulse is delivered with epidermal cooling, and the first few are at the edge so that you know what the sensation is before the more sensitive parts
Men are treated on the same principles and with the same arrangements, including the offer of a chaperone
Consultations are conducted in English with time for questions, and WhatsApp enquiries are answered in English and Chinese. If anything about the arrangements would make the treatment easier for you, it is simpler to say so at the consultation than on the day.
“In this area the skin is always darker than the chart says. I set the laser for the darkest part I am treating, never for the lightest.”

Which wavelength for the brazilian area: 755 nm or 1064 nm by skin tone
Genital skin is more pigmented than the skin of the limbs in almost everyone, and the difference is larger in Fitzpatrick III to V, which is most of Singapore. The hair is coarse, dark and dense. Both features concentrate energy: plenty of melanin in the hair, and more melanin than expected in the skin around it. That combination is why wavelength and cooling matter more here than on the arms, and why a protocol copied from the legs is the wrong starting point.
The platform used here carries a long-pulsed 755 nm alexandrite and a 1064 nm Nd:YAG. The 755 nm wavelength is strongly absorbed by melanin, which is effective on hair and unforgiving of pigment in the skin. The 1064 nm wavelength is less readily absorbed by melanin in the upper skin and penetrates deeper, so more of the energy reaches the follicle rather than the surface. Reviews of laser hair removal in darker skin consistently identify the long-pulsed Nd:YAG as the wavelength with the wider safety margin, and in this area the skin is darker than the chart says even on a light-skinned person.

What needs care
Bikini line and mons
Same as the body, often tanned at the edges
755 nm on Fitzpatrick I to III; 1064 nm on IV to VI
A tan line is read as tanned skin and treated as such
Labia majora and perineum

1064 nm Nd:YAG in most people; 755 nm only at conservative settings on light skin
Thin skin, years of waxing and shaving; cooling and lower energy
Perianal area

1064 nm Nd:YAG
Most heat-sensitive; treated last, at the most conservative settings
Any part, recently waxed or inflamed

Inflamed skin absorbs more energy and marks more readily
Neither wavelength is better in the abstract. The choice is made part by part, and the comparison between these two and the diode lasers used in many salons is on diode vs alexandrite vs Nd:YAG. Post-inflammatory pigment change is the main risk in this area, and the darker the skin the more conservative the settings and the closer the review.
Ingrown hairs and folliculitis in the bikini area: why they are settled first
The bikini area is where ingrown hairs and folliculitis are most common, and they are the reason many people ask about laser in the first place. Coarse, curved pubic hair cut by a razor or snapped by wax regrows with a sharp tip that curls back into the skin or tracks sideways under it, producing a tender bump, sometimes a pustule, and in darker skin a brown mark that outlasts the bump itself. Friction from underwear and the warmth and moisture of the area keep the cycle going.
Laser hair reduction helps because fewer, finer regrowing hairs mean fewer sharp tips and less shaving, which is the mechanism rather than any direct effect on an existing bump. Long-pulsed Nd:YAG has been studied specifically for the equivalent problem on the beard in darker skin, pseudofolliculitis barbae, and the same logic applies here. But inflamed skin absorbs more energy and marks more readily, so active bumps, pustules and broken skin are settled before any pulse is delivered. Where bumps persist or look unusual, the cause is examined, since bacterial folliculitis, fungal folliculitis, an infected cyst and some sexually transmitted conditions can all present as bumps in this area and need a different plan.
Between visits
Shave with a clean, sharp razor and no pressure, in the direction of growth, once the skin has settled
Do not wax, sugar, pluck or epilate, because that removes the hair the next session needs and restarts the ingrown cycle
Loose, breathable underwear reduces the friction that keeps follicles inflamed
Any bump that is hot, spreading or has a head is looked at rather than treated through
How brazilian laser hair removal is done here, and who should wait
Treatment runs on the R2 Glow platform, a long-pulsed laser carrying both 755 nm alexandrite and 1064 nm Nd:YAG, and every session is performed by Dr Sin Yong after examining the skin of each part on the day. The area is shaved beforehand, not waxed, so that the hair shaft and its pigment stay in the follicle; shaving a day or two ahead is better than on the morning, because freshly shaved skin is often nicked. Any numbing cream is discussed in advance rather than applied without the doctor knowing, because it changes how the skin feels heat.
A brazilian is commonly planned together with the underarms and legs in the same consultation, but each area is set independently. Visits are staged and timed to the hair cycle of this area, settings are adjusted to how the skin responded to the last visit, and the plan is reviewed rather than fixed as a package. What decides the spacing and the length of a course is set out on what decides the number of sessions. Whether the hair here will respond well depends on its colour and thickness and on your skin type, and that is said plainly at consultation.
Reasons to wait or to be referred
Pregnancy, including while trying to conceive, when the area is deferred
Recent waxing, active folliculitis, broken skin, or a flare of genital herpes; a herpes history is declared so that antiviral cover can be discussed
Recent isotretinoin or a photosensitising medicine, until discussed
A tan line, self-tan or sunburn over the bikini area, until it fades
Dark or changing moles, warts or any lesion in the area, which are checked before treatment and avoided
White, grey or very fine hair, which carries too little pigment for any laser; electrolysis is the alternative and is not offered here
Aftercare for the brazilian area
Afterwards the area feels warm and looks red, with small raised bumps around the follicles, and the labia and perianal skin can feel tender at first. A cool compress helps, and a bland, fragrance-free moisturiser or a soothing gel is enough. For the rest of the day and until the warmth has gone: loose cotton underwear rather than anything tight or synthetic, no hot baths, saunas, swimming or vigorous exercise, and no friction on the area, which includes sexual activity while the skin is still red. Fragranced washes and wipes sting on freshly treated skin and are left until it has fully settled.
In the period that follows, treated hairs push out and shed, which can look like regrowth; it is the hair leaving the follicle. Small crusts sometimes form over the densest hair and come away on their own. Shaving is fine once the skin has settled; waxing and plucking are avoided between visits. A blister, spreading redness, a bump that becomes hot or has a head, or a patch that turns darker or lighter than the surrounding skin is reviewed rather than waited out, and because this is skin that is normally covered, a photograph sent on WhatsApp during clinic hours is often enough to decide whether a visit is needed.
Sun protection matters at the edges of the area, since a tan line between visits shifts the wavelength choice. The general sequence of recovery and scab care is on the laser hair removal aftercare page.

Book an assessment with Dr Sin Yong on Orchard Road; the extent of the area and the arrangements are agreed before anything else. How consultations work.
The pubic region as a whole: the mons, the labia majora, the perineum and the perianal area, either completely or leaving a strip or triangle at the front. A bikini line clears only the edges beyond the underwear line. The extent is agreed and mapped with you before the first visit and kept the same at each one, and changing it later is straightforward.
Every session here is performed by Dr Sin Yong after assessment. Treatment is in a private room, only the part being treated is uncovered, and a chaperone from the clinic team is offered for every intimate treatment and present whenever you want one; you can also bring someone. You can stop at any point, and nothing is photographed. Men are treated with the same arrangements.
It can be, when the wavelength matches the skin. Genital skin is more pigmented than the limbs in almost everyone, so the 1064 nm Nd:YAG, which is less absorbed by surface melanin, is the usual choice, with 755 nm reserved for conservative settings on lighter skin. Epidermal cooling runs with every pulse, the perianal area is treated at the most conservative settings, and post-inflammatory pigment change is the risk that settings are chosen to avoid.
It helps by reducing the cause. Ingrown hairs come from coarse, curved hair cut by a razor or snapped by wax regrowing with a sharp tip that curls back into the skin. Fewer, finer regrowing hairs mean fewer sharp tips and less shaving. Laser does not treat an existing inflamed bump, which is settled first, and bumps that persist or look unusual are examined, because folliculitis, cysts and some infections look similar.
Yes, if you are comfortable; a tampon or menstrual cup is used and the area is draped as usual. Some people find the skin more sensitive in the days before a period, and it is reasonable to move the visit if that is the case. Pregnancy is different: the area is deferred during pregnancy and while trying to conceive, because hair growth often changes afterwards and treatment in pregnancy has not been studied.
