Nature Republic The Jin EGF Essence Booster


One of Korea’s fastest growing Cosmetic company, Nature Republic, has announced today a new product called The Jin EGF Essence Booster.


So what is EGF and this obsession with EGF in Korean cosmetics lately?  What does it stand for?



EGF simply stands for Epidermal Growth Factor. It is a growth factor that plays an important role in the regulation of cell growth, proliferation, and differentiation by binding to its receptor EGFR. There is research showing it to be helpful for wound and burn healing


EGF is the perfect marketing tool in cosmetics because the discovery of EGF won Stanley Cohen ( University of Vanderbilt) a Nobel Prize in Physiology and Medicine in 1986 and was then later patented for cosmetic use by Greg Brown in 1989.


However, there is also research showing that its effect is no different from that of a placebo and that it may not even be effective when applied on the skin. EGF causes hair loss and is used commercially to remove wool from sheep. Clinical studies of EGF has also been reduced because of its toxicities, and at certain concentration and lengths of application, it may cause cells to overproliferate ( thus causing cancer ). There is no exact proof to this.


However i doubt that the EGF concentration here is anyway high at all, and probably below 0,5%  or much less than that, considering it’s rather cheap price. The price is very affordable like all Nature Republic products, and probably worth a try.



The Nature Republic EGF line will boost 3 products – lotion, essence, cream, eye cream and sooner or later, a BB cream!


Retailed for 28,000 Korean Wons / 40ml .

  1. Hi, I tried for several days now to place an order at Gmarket, everything is right but when I finish ti fill information of credit card( and I tried 2 different cards) it always end with the error code -344 and my order is automatically cancel ! Does someone else get the same problem ? How can I contact them to ask for what happen and how to resolve the problem . Any help greatly appreciated .

  2. I tried the Hanskin EGF Repair Cream before. The concentration is obviously not high as to constitute cancer, but I loved the texture of the cream, which contained many other moisturizing ingredients including beeswax, hydrogenated vegetable oil, shea butter, and so on.

  3. Hey Hope, actually, you might guess the answer to this for someone like me who thinks that Korean skincare thrives on advertising, but still has a strong sense of customer loyalty to the LG or Amore brands. I think the thing with NR and The face Shop is that for me, and even for a lot of Korean friends I know, as much as there is novelty in the products launched constantly by them, the novelty fades off compared to the customer loyalty that sticks to the star power products in department stores and higher-end cosmetic outlets like Whoo’s Qi and Jin cream, Hannule’s Go Gyeol Jinaek cream, or Sulwhasoo’s mask packs. I might try out brands like NR,or The Face Shop for some of their new products once in a while, or indulge in an occasional mass market shopping spree in The face Shop or NR especially for the price it offers compared to Japanese toiletries’. (Japanese toiletries simply cannot match up in terms of pricing and efficacy to be honest in my opinion, since I think that the element of cosmetic use also has to deal with marginal utility that flows from a willingness to spend on the products other than their active ingredients). But still, the few brands which I like for their star power products are what I stick to for their tried-and-tested formulas. Well, now, you know what I use for my skincare daily or weekly
