O2 Clinic Review: GP-Led Aesthetic Clinic Group in Ayer Itam, Penang

Overview of O2 Clinic

O2 Clinic began in January 2012 as a Penang medical and aesthetic group. Its headquarters sits at 1 & 1M, Jalan Ayer Itam, under signs that read both "O2 CLINIC" and "O2 KLINIK". The group also runs branches in Kedah, Perak, the Klang Valley, Johor and Pahang, but this O2 Clinic review focuses on Penang.

Two sides of one brand

Each branch is first a general practice. On top of that, most branches run a separate aesthetic service with its own hours and phone line. So the same building may treat a fever at midnight and offer pico laser by day.

This matters because the clinic you walk into depends on what you need. If you want skin or aesthetic treatment, pick one of the nine Penang branches with aesthetic services. The other three offer GP care only.

Where O2 Clinic fits in our top 10

We rank O2 Clinic third. Its strengths are reach, long opening hours and a wide treatment menu under one brand. However, it is not a specialist dermatology practice. None of its listed doctors is described as a dermatologist, so it suits cosmetic and everyday skin concerns better than complex skin disease.

About the doctors at O2 Clinic

O2 Clinic publishes its doctors on an official "Our Doctors" page. Their titles are "Consultant Aesthetic Physician" or "Consultant Medical Physician". None is described as a dermatologist, and the clinic does not claim specialist registration for any of them.

Branch medical directors in Penang

• Dr Koay Chun Hang is the group CEO and leads the Ayer Itam HQ. Listed qualifications are an MBBS (IMU), an LCP in aesthetic medicine, dermatology diplomas from Malaysia and Bangkok, and a fellowship in cutaneous and laser surgery (Bangkok).
• Dr Leow Shin Chee (Heritage) and Dr Kerwin Oh Shen Way (Jelutong) both hold an LCP and a Malaysian dermatology diploma.
• Dr Gan Boon Keong leads Summerton, with an LCP, a US aesthetic medicine diploma and a Malaysian dermatology diploma.
• Dr Wayne Tan Chern Wuay leads Tanjung Tokong, and Dr Tiow Choo Aik leads Relau as a Consultant Medical Physician.
• On the mainland, Dr Eric Teoh Sze Loong (Raja Uda) lists primary care dermatology. Dr Lee Tsang Chin leads Bukit Mertajam, and Dr Dennis Boon Poh Oon leads Batu Kawan.

What these titles mean for you

An LCP (Letter of Credentialing and Privileging) is the Malaysian permit that lets a registered doctor perform aesthetic procedures. The clinic says all its aesthetic treatments are done by LCP-holding doctors. A diploma in dermatology is a primary care qualification. It is useful training, but it is not specialist registration. Also, doctors differ by branch, so ask which doctor you will see when you book.

Services and treatments

O2 Clinic offers a broad aesthetic menu. On the face, it lists acne care, acne scar work, pigmentation treatment, chemical peels, medical facials, microneedling, pico laser and HIFU. Injectables include botulinum toxin, fillers, thread lifts, skin boosters and PRP. In addition, there are body treatments such as fat freezing and EMS contouring, plus hair loss care and laser hair removal.

The group also runs men's health and GP services, plus a separate dental clinic in Jelutong. Because so much sits under one brand, start by telling reception exactly what you want. Then ask which branch and doctor handle that treatment.

Conditions treated

The aesthetic website lists everyday skin conditions alongside cosmetic concerns. These include acne, eczema, psoriasis, fungal rashes, warts, skin tags, moles and pigmentation. It also mentions scalp problems and suspicious growths.

A GP-led clinic is a sensible first stop for mild acne, rashes or a wart. However, for severe or persistent eczema or psoriasis, or a changing mole, ask for a referral to a dermatologist. In Penang, Lim Skin Specialist Clinic and Gleneagles Penang dermatology are led by specialists.

• Acne
• Acne scars
• Pigmentation
• Freckles & age spots
• Uneven skin tone
• Wrinkles & fine lines
• Skin laxity
• Keloids & scars
• Moles & skin lesions
• Eczema
• Psoriasis
• Fungal skin infections
• Warts & skin tags
• Hair loss
• Unwanted hair
• Stretch marks
• Tattoos
• Stubborn fat

Technology and equipment

The official sites name several devices. These include a pico laser (sold as "Pico2", with "PicoNude" for hair removal), Medlite and other Q-switched lasers, a fractional CO2 laser and Sylfirm X radiofrequency microneedling. There is also HIFU, cryolipolysis, EMS body contouring and an Emchair for the pelvic floor. The clinic says its laser technology is MDA approved.

In general terms, pico and Q-switched lasers target pigment, so clinics use them for spots, melasma and tattoos. Fractional CO2 lasers and RF microneedling are often used for acne scars and texture. HIFU is a non-surgical option for mild skin laxity, while cryolipolysis and EMS target body fat and muscle tone. Also, not every branch may stock every device, so check before you book.

Pricing at O2 Clinic

O2 Clinic publishes only one price that we could confirm. The HIFU trial treatment is listed at RM299 at selected clinics. The promotions page lists other "1st Trial" offers, but without prices in the page text.

For everything else, O2 Clinic prices are not published. At your consultation, ask for the full cost of a course, not a single session. Also ask whether the consultation fee is separate, and how many sessions the doctor expects. Finally, check whether a trial price applies at your chosen branch.

Prices as published by the clinic when we checked. Confirm the current price before booking.

Picking a branch

If you live in George Town, Heritage and Jelutong are the closest. Ayer Itam HQ has the longest aesthetic hours and the CEO's own clinic. Southwest island residents can try Summerton or Relau. Meanwhile, mainland patients can avoid the bridge by using Raja Uda, Bukit Mertajam or Batu Kawan.

At the Ayer Itam HQ, aesthetic services run 10am to 7pm daily, and the GP side is open 24 hours. Elsewhere, aesthetic hours vary: most branches open 9am to 6pm daily, but Raja Uda is closed on Wednesday, Bukit Mertajam (9am to 5pm) on Tuesday and Batu Kawan (10am to 7pm) on Thursday. The site footer shows older hours that conflict with the branches page, and public holiday hours are not stated, so call before visiting.

Aesthetic services at the Ayer Itam HQ, 10am-7pm daily (official branches page, checked 2026-10-14). Medical (GP) services at HQ run 24 hours daily. Aesthetic hours differ by branch: most are 9am-6pm daily, Raja Uda is closed Wednesday, Bukit Mertajam (9am-5pm) is closed Tuesday and Batu Kawan (10am-7pm) is closed Thursday. The site footer shows older, conflicting hours, so the branches page was used.

What patients say about O2 Clinic

4.9 out of 5 on Google Maps (checked 14 Oct 2026)

On 14 October 2026, the Google Maps listing for O2 Klinik Aesthetics (Ayer Itam) showed 4.9 stars. Each branch has its own listing, so scores differ by branch. Google hides the review count when you are not signed in, so we cannot say how many reviews it covers. Instead, here are the main themes.

On the positive side, patients describe clear improvement in pigmentation after a course of laser sessions. Many mention friendly, responsive doctors and staff who explain each step. The clinic's own testimonials also say prices feel affordable and that staff do not push hard sales.

On the negative side, some patients report long waits at certain branches, even with an appointment. They put this down to too few doctors and nurses. In addition, a third-party listing for the Heritage branch carries complaints about slow customer service and staff attitude. Experiences seem to vary by branch, so read recent reviews for the branch you plan to use.

Pros and cons

Who this clinic is best for

O2 Clinic suits people who want aesthetic treatment close to home, wherever they live in Penang. It works well for pigmentation, acne marks, ageing concerns and body contouring, especially if you value evening or weekend slots.

However, look elsewhere if you have severe acne, a chronic skin disease or a mole that worries you. In those cases, a dermatologist-led clinic such as Lim Skin Specialist Clinic is a better first step. You can also compare all options in our top 10 list.

How to book
