The Dermatology and Laser Surgery Department at Ramkhamhaeng Hospital utilizes advanced technology to offer treatments for skin diseases as well as facial and body aesthetic laser care, performed by a team of medical specialists in skin lasers and aesthetics, including:
Both technologies are highly effective in removing skin tumors, moles, skin tags, and warts with high treatment safety. They cause minimal damage to surrounding tissue, allowing rapid healing and effectively reducing the risk of post-treatment scarring.
We utilize the Medlite C6 by Hoya Conbio, a high-performance technology designed to treat skin pigmentation irregularities. This laser can correct both superficial and deep freckles, congenital birthmarks, hyperpigmentation, melasma, and tattoo removal

We use lasers certified for efficacy by the United States Food and Drug Administration (US FDA). The laser energy targets wrinkles, fine lines, and acne scars by penetrating deep into the skin layers while protecting the outer skin with integrated cooling. Appropriate energy levels stimulate connective tissue cells to produce increased collagen and elastin. This tightens the skin and reduces wrinkles and scar indentations. Additionally, it safely removes unwanted hair, hair-nourishing blood vessels, and spider veins.


Sellas, also known as Fractional laser, delivers light energy in the Mid-Infrared range, which is easily absorbed by dermal tissue. The Sellas laser light creates thermal points deep within the dermal layer to stimulate new collagen synthesis. As a result, acne scars become noticeably shallower, and wrinkles are visibly reduced after approximately 4–6 treatments without causing bleeding. In addition, the depth and density of the laser can be adjusted to match individual skin tones and conditions. Key Highlight: Delivers treatment efficacy comparable to ablative lasers, but with minimal side effects and zero downtime.
Featuring Dual mode filtering Square pulse IPL technology, which surpasses standard IPL systems. Key advantages include: consistent energy delivery through a large glass crystal guide that covers broad areas for fast and effective treatment. Dual-mode wavelength filtering minimizes side effects caused by water absorption in the skin, enhancing safety even without cold compresses. Ellipse IPL helps rejuvenate skin for a brighter complexion, reduces dark spots, mild melasma, superficial freckles, post-acne dark and red marks, wrinkles, and provides fast hair removal with minimal discomfort.


High-performance laser innovation for pigment disorders and tattoo removal. Resolves pigment issues rapidly with reduced post-treatment side effects, tailored to meet every requirement by specialized dermatologists and laser specialists.

Corrects wrinkles and enlarged pores, reduces uneven skin tone, redness, hyperpigmentation, superficial freckles, and firms sagging skin. Featuring E Matrix technology, which delivers radiofrequency energy deep into the skin layers to effectively treat acne scars with low side effects.

Pigmentation disorders, melasma, post-inflammatory hyperpigmentation, subcutaneous vascular abnormalities, acne redness, minor varicose veins, reduces acne inflammation while speeding up the fading of acne marks, and helps diminish the appearance of stretch marks and scars.
Radiant, confident, and safe with comprehensive aesthetic technology by dermatologists specializing in skin lasers.
