IV Drip

An IV drip delivers fluid and selected substances directly into a vein. It can be useful when there is a medical reason for intravenous treatment, but faster delivery does not prove better health, brighter skin or more energy in someone who already gets enough nutrients.

Smooth Clinic lists Skin Bright, Immune Booster and Liver Detox programmes, with single-session prices of 990–1,490 THB. Before choosing one, the important questions are what it contains, whether an IV is appropriate for you, and what benefit you can reasonably expect.

IV Drip programmes and prices at Smooth Clinic

The following offers were checked on the clinic’s current price list (Thai) on 15 October 2026 (Thailand time). These are programme names, not standardised medical formulas or guarantees of whitening, infection prevention or liver cleansing.

The price cards do not establish the ingredients in each programme. Ask for the proposed product list and the reason for including each substance before deciding. A formula mentioned in another clinic’s advertisement, or in a general vitamin guide, may be different.

Confirm the current total, any consultation or testing charges, package validity, bonus-session conditions and cancellation or refund terms before paying. A five-plus-three offer is a commercial package, not a recommendation to undergo eight infusions. Medical suitability should come before buying multiple visits.

Do you need an IV, or would oral treatment be enough?

IV means intravenous. Delivery through a vein bypasses absorption in the gut; it does not mean every nutrient will be used for your intended goal. For example, IV vitamin C can reach higher blood concentrations than oral vitamin C, but the concentration alone does not demonstrate a cosmetic or wellness benefit.

A diagnosed deficiency needs treatment suited to its cause and severity. Many nutritional needs can be met through food or oral supplements. An intravenous route may be considered when oral treatment is unsuitable or inadequate, including particular absorption problems. Having a deficiency does not automatically mean you need a drip.

For dehydration, drinking fluids may be sufficient if you can drink and retain them. A pharmacist can advise about oral rehydration solutions when vomiting or diarrhoea has caused fluid loss. Persistent dizziness on standing, very little urine or a fast heartbeat needs prompt medical assessment; confusion or difficulty breathing needs emergency care. A wellness appointment should not delay that assessment.

Compared with oral treatment, an IV adds the cost and time of a clinic visit and the risks of entering a vein. Its value depends on a genuine reason to use that route, rather than a claim of “maximum absorption”. Our guide to oral and injectable vitamin C explains the distinction in more detail.

What does the evidence say about energy, skin, immunity and detox?

Fatigue and energy

A drip should not be the first explanation for why you feel tired. Poor sleep, stress, anaemia, thyroid problems and other illnesses can cause fatigue. If it lasts several weeks, affects daily life or comes with symptoms such as weight loss or palpitations, arrange a medical assessment.

There is some limited research: a randomised trial analysing 141 office workers found lower self-reported fatigue after one IV vitamin C administration, assessed at two hours and the next day. It did not establish long-term benefit, a repeat-course schedule or effectiveness of Smooth Clinic’s programmes. Feeling temporarily refreshed also does not identify the cause of fatigue. Read the primary fatigue study.

Skin brightening, pigmentation and ageing

Vitamin C supports normal collagen formation, but that biological role is not proof that giving more through a vein will whiten skin or reverse ageing. There is no dependable number of wellness drips that can be promised to change your skin tone permanently.

Research on IV glutathione for skin lightening is limited. One small placebo-controlled study used a mixed product, lost many participants from its final analysis and reported adverse effects. It cannot establish a reliable benefit or safety profile for different formulas. In a notice dated 13 May 2025, the Thai FDA said it had not certified the safety of glutathione injections for cosmetic purposes (Thai).

For dark spots or uneven tone, identifying the cause and using appropriate sun protection can be more useful than choosing a drip by its name. See our guides to skin-focused vitamin injections and their limitations and glutathione evidence and safety.

Immune support and “detox”

Adequate nutrients are necessary for normal immune function. Correcting a deficiency is different from showing that extra nutrients prevent infections in a well-nourished adult. An “Immune Booster” name does not establish protection from colds or other infections, and an infusion does not replace vaccination or treatment for an illness.

“Liver Detox” is a programme label, not evidence that a drip removes unspecified toxins, repairs alcohol-related damage or treats liver disease. If you have abnormal liver tests or concerns about alcohol use, seek a medical assessment rather than using the programme as a substitute. A medically justified use of an ingredient in a particular condition cannot be transferred to routine wellness use.

What should be checked before treatment?

The assessment should establish your goal, whether there is a treatable cause for your symptoms, and whether intravenous delivery offers enough benefit to justify its risks. Tests may be appropriate for particular symptoms or ingredients; there is no single blood-test package that proves every wellness drip is needed.

Discuss kidney disease or stones, heart or liver disease, fluid restrictions, iron overload, known G6PD deficiency, allergies or previous severe reactions, pregnancy or breastfeeding, and your medicines and supplements, including cancer treatment. This allows the clinician to assess the proposed substances and possible interactions rather than relying on a programme name.

High-dose IV vitamin C needs particular caution. It can cause kidney complications, break down red blood cells in people with G6PD deficiency, and be unsuitable in iron-overload conditions. It may also interfere with some glucose and other laboratory tests. Tell the team arranging those tests about a recent infusion so results can be interpreted appropriately; this warning does not mean that every IV contains high-dose vitamin C.

Age alone does not identify a deficiency or the right formula. Our educational guides for people in their 20s, 30s, 40s and 50s and beyond discuss different life-stage concerns, but do not replace an individual assessment.

What can you expect at an appointment?

In general, an IV visit includes assessment, an explanation of the proposed treatment and alternatives, placement of a small cannula in a vein, observation during the infusion, and a check before leaving. These are general expectations for care; confirm the arrangements for your appointment with the clinic.

Ask whether any preparation or fasting is needed, particularly if tests are planned. Follow existing fluid restrictions rather than drinking large amounts to make needle insertion easier. If you develop a fever or feel acutely unwell before the visit, contact the clinic for advice about assessment rather than pushing ahead with a wellness treatment.

A brief needle prick and later bruising are possible. Burning, increasing pain, swelling or skin changes during the infusion should be reported immediately. Do not adjust the drip or its equipment yourself.

There is no single appointment length for all programmes. The substances, fluid volume, appropriate administration time and observation needs affect the total. Ask for an estimate that includes assessment and observation, and do not arrange for an infusion to be rushed to fit a work break or flight.

Side effects and when to get help

Possible effects include tenderness, bruising, nausea and lightheadedness. More serious complications include vein inflammation, fluid leaking into surrounding tissue, infection, fluid or electrolyte problems, interactions and severe allergic reactions. Their likelihood depends on the product, preparation and your health; supervision does not eliminate every risk.

• During treatment: alert staff immediately if you develop pain, swelling, a rash, dizziness or feel unexpectedly unwell. Do not wait for the bag to finish.
• Emergency symptoms: difficulty breathing, throat tightness, sudden lip or tongue swelling, or collapse need immediate emergency care. If they occur after you leave, seek emergency help rather than waiting for a clinic chat reply.
• Prompt assessment: fever, chills, worsening redness, warmth, swelling or pain around the puncture site need medical attention, including when they start later. These are not signs of a normal “detox”.

Afterwards, follow the instructions for the puncture site and keep it clean. Before leaving, know whom to contact for non-emergency concerns and when any follow-up is due. Do not drive if you feel dizzy or unwell.

How soon should you notice a difference, and should you repeat it?

For treatment of a diagnosed deficiency or dehydration, the outcome and follow-up depend on the condition being treated. For wellness goals such as more energy, brighter skin or anti-ageing, there is no established timeline or lasting effect that applies across formulas.

A short-lived feeling of improvement does not prove that weekly or monthly infusions are necessary. Equally, a lack of change is not a reason to increase the substances or frequency. Before another session, review whether there was a meaningful benefit, whether symptoms need investigation, and whether any adverse reaction occurred.

Do not continue an elective course simply because visits remain in a package. If you are receiving medically necessary treatment for a diagnosed condition, discuss changes with the treating clinician rather than stopping solely because you feel better.

Choosing a provider and checking the products

Ask who will assess and supervise your treatment, what qualifications they hold, and how the facility responds to an acute reaction. You should be able to understand the proposed ingredients, expected benefit, alternatives and risks before consenting. If you need the discussion or aftercare instructions in English, confirm that arrangement when booking.

Ask to identify the actual injectable products, their manufacturer, batch and expiry details, and their traceable supply. Product registration or genuine packaging alone does not establish that a particular cosmetic claim is proven. Sterile preparation and appropriate single-use needles, cannulas and infusion sets also matter.

The U.S. FDA has warned about serious reactions involving injectable glutathione made with dietary-supplement-grade material, which is unsuitable for injection. This is a foreign safety warning, not a report about Smooth Clinic. It explains why a familiar vitamin name or the words “medical grade” are not enough to verify a product. Read the FDA warning.

Reviews can help you assess communication and the visit experience. They cannot show that you need an infusion or predict your medical or skin result.
