Frequently Asked Questions
WHAT IS REJURAN?
Rejuran, otherwise known as 婴儿针, is made of polynucleotide (PN or PDRN) which has wound-healing and anti-inflammatory properties. In addition to its safety, stability and good biocompatibility with human skin, it restores the extracellular matrix by activating the skin’s self-generating abilities while improving the skin condition from within. Many studies have shown that PN stimulates cell growth and wound healing from inside out.
HOW DOES PN WORK WITHIN THE SKIN?
The PN in Rejuran revitalises the skin by promoting cell growth through fibroblast production. This way it improves the skin’s own regenerative capability, improves skin elasticity, and skin tone and texture by balancing oil and moisture levels in the skin.
WHO MAKES THE BEST CANDIDATE FOR REJURAN?
The best candidates for Rejuran are those with pigmentation and otherwise damaged skin from sun exposure and those with fine lines and wrinkles around the mouth and eyes, as well as those who suffer from chronic inflammation of the skin such as acne, resulting in acne scars. Along the same vein, it is also effective for treating eczema. Patients with thin and/or sensitive skin who are not suitable for, or may have experienced side effects from treatments such as fillers can also benefit from Rejuran.
HOW IS THE TREATMENT ADMINISTERED?
The treatment is administered via superficial intradermal injections with a sharp needle all over the face, including the forehead, cheeks, temples, upper and lower eyelids and the periorbital and nasolabial areas. This causes temporary weals that look a little like mosquito bites but subside within 24 hours.
The patient can choose to take an oral analgesic such as nonsteroidal anti-inflammatory drugs (NSAIDs) or paracetamol prior to the treatment. Numbing cream is then applied followed by injections of local anaesthesia into the areas to be treated. During the treatment, the physician might ask his or her assistant to place packs of ice on areas to be treated to further reduce pain and the areas already treated to reduce the formation of weals.
HOW LONG DOES EACH TREATMENT TAKE?
The treatment takes about 10 minutes, not including time needed for the effects of the numbing cream to set in.
IS THE TREATMENT PAINFUL?
Injections in areas such as the upper and lower eyelids and under-eye and cheek areas are practically painless. However, the patient might feel discomfort and even pain in the more sensitive areas such as the forehead and jawline.
FOR BEST RESULTS, HOW MANY TREATMENTS ARE NEEDED?
For best results, the patient is advised to have up to three or four treatments, spaced three to four weeks apart between treatments.
IS REJURAN USED IN COMBINATION WITH OTHER TREATMENTS? WHAT ARE THEY?
Like most other aesthetic treatments, Rejuran can be used in combination with other treatments for example CO2 fractional lasers to further assist in treating acne scars, thread lifts for repositioning of sagging facial tissue, and non-crosslinked hyaluronic acid fillers to provide more radiance and hydration to the skin.
WHAT ARE THE DESIRED EFFECTS OF REJURAN?
Rejuran can provide improved skin elasticity, collagen synthesis in the skin, tighten and lift skin, balance the oil and moisture levels in the skin, reduce the appearance of acne scars and open pores, and improve fine lines and skin texture. It also increases the protective layer of the skin by increasing thickness and density of inner skin.
