水光针 is also known as skin collagen booster, or skin booster. In fact, the more popular products are from Europe or Korea, not Japan. It is very popular among Korean and Taiwanese actors and actresses.
There are a few clinics in Singapore offering this service but it is not cheap. This clinic Dr Tan & Partners @ Scotts offers a very affordable price in comparison to other aesthetic clinics. http://skinaesthetics.sg/article/skin-boosters-水光针
