Today I test for you a serum called BIOEFFECT – EGF Serum. This is an anti-aging product that is produced with human-like EGF (Epidermal growth factor). EGF accelerates skin cell renewal and stimulates the production of elastin and collagen, according to the beauty brand. I have tested this product for about a week and can report … The serum takes longer to be absorbed by the skin, but leaves no residue. The skin feels very soft and comfortable warm after application and even hours later. It is as if the skin is covered with a silk cloth. The serum is very productive. The manufacturer recommends one or two drops of the face and neck, but I just needed one drop. I have applied the serum, as recommended by the brand, evenings and no longer used my night cream, because the serum was completely enough as maintenance. A further advantage is that the serum is suitable for all skin types. After a week, I could not tell exactly whether a skin cell renewal has taken place. What was clearly to be recognized is an improvement of the skin structure. It was smoother and more clear. The product shows positive results and is certainly an asset to the skin. I hope you can see the result a little bit on the picture!
