Dr Jinah Yoo Dermatology offers consultation and treatment for any skin rashes. In more challenging or uncertain type of rashes, you may need further investigations and we provide a full range of investigations to help with the diagnosis and management.

Skin Biopsy

Sometimes, skin biopsy is taken to look at deeper layers of the skin under the microscope to confirm the diagnosis. It involves numbing injection under the skin at the site of biopsy followed by taking a small skin sample:

  • Curettage or shave biopsy is performed using a blade/curette to shave off the raised skin lesion and then burn off the bleeding vessels at the base. Initial wound would be a black scab which falls after within 7-10 days

  • Punch biopsy is performed by using a device which looks like a small apple core (usually 4mm diameter) and take a sample of the skin lesion/rash which can go down to deeper layer of skin (dermis) and fat tissue to give us a full picture of the pathogenesis

Skin Scraping

If there is a suspicious fungal/yeast infection causing the skin rash, skin scraping is performed and sent to the lab to see what type of fungus/yeast is causing the rash which helps to target with the right type of antifungal medication

Skin Swab

If there is a suspicious bacterial infection causing the skin rash, skin swab is performed and sent to the lab to see what type of bacteria is causing the rash which helps to target with the right type of antibiotics

Blood Test

We have an affiliated lab where blood sample taken from our clinic is analysed. Blood test is sometimes required to see any associated conditions which can cause the rash as well as to monitor bloods whilst on medication for the skin rash

Treatments

Once the diagnosis is made, the best treatment plan will tailored to meet each patient’s needs which may include prescription of topical/oral medication or combination treatment with procedures such as laser, peels, LED, injectables, oral supplements or skincare.
