Lemon Bottle

What it is

Lemon Bottle is a brand name, not a compound. It is a 'lipolysis' product sold to dissolve small pockets of fat, such as under the chin, and is typically used with injections or microneedling. The contents depend on the manufacturer. Deoxycholic acid or phosphatidylcholine (sometimes with other ingredients) is typical. It is not a peptide.

Be clear about what you are buying. The formulation, concentration and sterility of grey-market 'Lemon Bottle' products are often not verified, and you cannot assume it matches a licensed medicine of similar composition. Read the label and batch information, and treat any product with no clear ingredient list as unsafe to inject.

History

Deoxycholic acid is a bile acid that the body uses to break down dietary fat. A synthetic version was approved by the US FDA in 2015 as Kybella for fat under the chin, and is marketed in Europe as Belkyra. Phosphatidylcholine/deoxycholate injections were used for years in aesthetic clinics before that without formal approval, and regulators have warned about unapproved fat-dissolving injections. 'Lemon Bottle' became a social-media-driven brand in the early 2020s.

How it works

Deoxycholic acid disrupts the membranes of fat cells so that they burst, and the body then clears the debris over weeks. This is permanent for the cells treated, and it is also not selective: it damages other cells it contacts, including skin, muscle and nerves. That is why correct placement and dose matter.

Dosage

• We do not give a dosing protocol for this product. The licensed deoxycholic acid medicine (Kybella) is injected in tiny, spaced amounts by trained clinicians, within a set maximum per session. The risk from off-label self-injection is high, and the concentration in a vial of unknown strength cannot be assumed.
• If you are determined to use a product like this, the right source of dose information is a licensed practitioner and the product's own documentation.

How it is taken

• In clinics, licensed deoxycholic acid is injected into the subcutaneous fat layer in a grid pattern, by someone who knows the nerve anatomy of the area. Several sessions about a month apart are typical.
• Other products are applied after microneedling or with a dermaroller. This is a different route with different, poorly studied risks.
• Self-injecting under the chin is a high-risk area because of the facial nerve (the marginal mandibular branch) that runs close to the surface.

How to reconstitute

• Not applicable: a 10 ml vial is a ready-to-use liquid. Do not dilute or mix it with anything unless the label says so.
• Check the label for the active ingredient and its concentration (mg per ml). If it does not give one, you cannot calculate a dose, and that is a good reason not to inject it.

How it should arrive

A sealed glass vial or bottle with a clear label listing active ingredients, concentration, batch number and expiry. Legitimate pharmaceutical injectables come with this information. A bottle with no ingredient list is a warning sign.

How it should look once reconstituted

A clear liquid, colourless to pale yellow, with no particles or cloudiness. Discard if cloudy, discoloured or if it contains particles.

What to expect, and when

• Swelling, bruising and tenderness appear almost immediately and can last days to weeks.
• Visible fat reduction in clinical use takes around 4-8 weeks after a session as the body clears dead fat cells. Multiple sessions are usually needed.
• Results are only seen for small localised areas; it is not a weight-loss method.

Side effects

• Significant swelling (often looking worse before it improves), bruising, pain, burning and numbness.
• Hardness, lumps and nodules under the skin.
• Redness, itching and skin tightness.
• Skin ulceration and scarring where it is injected too superficially.

Risks

• Tissue necrosis: if the product reaches the skin or tissue outside the fat layer, it can kill skin, leaving ulcers, scars or permanent marks.
• Nerve injury: the licensed Kybella label warns of injury to the marginal mandibular nerve, causing an uneven smile or facial weakness, and of difficulty swallowing. Usually temporary but can last months, and in rare cases may be permanent.
• Infection and abscess from non-sterile product or technique.
• Unlicensed products may contain unknown ingredients, wrong concentrations or contaminants. Unregulated fat-dissolving injectables have been the subject of regulator warnings.
• Allergic reactions.
• Not for use in pregnancy. Avoid with infection in the area, and be cautious on blood thinners.
• Being frank: this is one of the higher-risk items on the site. Self-injecting should not be the first choice, and a trained, registered practitioner using a licensed product is the safer route.

Potential gains

• Reduction of small, localised pockets of fat (the licensed use is under the chin), with real evidence for licensed deoxycholic acid.
• Evidence for the grey-market branded product itself is lacking.
• It is not weight loss and does not replace diet, exercise or medical weight management.

Other useful information

What is licensed: deoxycholic acid for fat beneath the chin, given by trained clinicians. What is not: most cosmetic 'lipolysis' solutions and phosphatidylcholine injections. If you want to treat fat under the chin, a consultation with a registered medical practitioner for the licensed medicine is the safer route. Because contents vary between vendors, verify the active ingredient before anything else.
