An anti-aging revolution from Iceland has been a topic of conversation for a long time: EGF from BIOEFFECT. In addition to numerous advantages, there are also one or two criticisms. We reveal the strengths and weaknesses of the products in our detailed BIOEFFECT EGF SERUM test report and explain who benefits from these serums and who is less attracted to the application will feel. You can also read everything here about the BIOEFFECT EGF SERUM experiences that our beauticians have had in the cabin with the anti-aging miracle weapons.




Our BIOEFFECT EGF SERUM test showed that the products offer the following advantages:

  • All-round products: The neck, face, décolleté and eyes can be treated with the EGF serums.
  • High tolerability: Germ-free conditions when growing the EGF protein and only 6 other ingredients make the products optimally tolerated by every skin type. Also for skin that suffers from couperose.
  • Quick care: The BIOEFFECT products are ideal for daily treatment at home thanks to their uncomplicated and quick application.
  • Long-lasting effect: Long-lasting freshness and radiant skin are long-lasting consequences after the treatment.
  • Better absorption of active ingredients: After treatment with the BIOEFFECT EGF SERUM, your skin begins to work much better again. If you then return to your classic cosmetic products, they will be much better absorbed by the skin after the EGF treatment.

Even though the BIOEFFECT EGF SERUM is an excellent all-round product, it is possible to address specific skin problems with other EGF products, such as the BIOEFFECT EYE SERUM . Since the eye area is much thinner and has less fatty tissue, products specifically for the eye area have other active ingredients that are tailored to the thin skin.


The care creams and the care feeling are positioned on the con side:

  • Care creams: Our beauticians see a disadvantage especially in the brand's care creams. There are currently only 2 creams in the range, which cannot cover all skin needs in the long term.
  • Care feeling: The EGF serums do not leave your skin feeling “creamed”. A disadvantage if you need a noticeable feeling of care in the evening.

Less disadvantage, but all the more important for successful treatment: Follow the instructions for use. It is important to wait 10 minutes after application before using another care product. Mixing EGF SERUM and care cream is very counterproductive. This creates a new product that will not achieve the desired effect.


In this test report we introduce you to the brand's current line. The BIOEFFECT Portfolio not only offers the EGF SERUM as an all-round product for the face, neck, décolleté and eyes, but now also care for the special areas.

With the EGF EYE SERUM , for example, standard problems in the eye area, such as classic expression lines, dark shadows and puffiness under the eyes, can be treated efficiently.

The 30 DAY TREATMENT impresses with an intensive 4 week treatment, which is recommended, for example, for customers who want to activate tired, thin and damaged skin, to counteract the signs of the times.

In addition, BIOEFFECT offers two care creams, the HYDRATING CREAM and the POWER CREAM. There is also the body serum EGF BODY SERUM and the peeling VOLCANIC EXFOLIATOR.

BIOEFFECT EGF SERUM night, day and eye treatment evaluation

Our beautician has had the following experience with the EGF SERUM:

“The BIOEFFECT EGF SERUM achieves a significant improvement in the skin’s appearance. The skin appears fresher, smoother and plumper, can retain moisture better and wrinkles are no longer as visible. In addition, the skin starts to work really well again, so that subsequently used cosmetic products are better absorbed.“ 

  • Application: The EGF SERUM can be used excellently as a treatment to pamper your skin with a special product and stimulate the renewal of skin cells. The serum is used in the evening because the composition of the product is tailored to the skin's significant recovery phase at night.
  • Duration: Use the EGF SERUM daily for a longer period of time. Since the skin cells need a few weeks to renew, the first results are visible with daily treatment from the 3rd day onwards. week visible.
  • Dosage: Take 3 drops of the serum for your face and add one drop for your neck and décolleté.
  • IMPORTANT: Let the serum sit for approx. Leave on for 10 minutes before applying another care product. This way you avoid mixing serum and cream so as not to jeopardize the effect.

After treatment with the EGF SERUM, you should switch back to products that are suitable for your specific skin type and address your individual skin problems. As our beauticians also recommend: “We see the EGF SERUM more in the spa area. Our customers usually switch back to other products after using 2 or 3 bottles, because their skin has very different needs. We don't necessarily recommend sticking with EGF permanently, but rather using the SERUM as an activating product for cell renewal in order to have more success with subsequent cosmetic products.“ 

“The BIOEFFECT EGF DAY SERUM is of course structured differently than the EGF SERUM. Although it also contains the epidermal growth factor, it also consists of moisturizing substances. You can think of it as a light emulsion, which gives the skin a bit of protection during the day.“

  • Application: The EGF DAY SERUM is applied to the face, neck and décolleté in the morning after cleansing and can be combined with the DAYTIME CREAM.
  • Dosing: It is enough if you press the dosing head of the bottle twice.
  • IMPORTANT: Please also note the 10-minute exposure time for this product before you put on your make-up, for example.

“The differences between the two EGF serums lie in the composition and period of use of the products. At night the skin works differently and we have a few hours of regeneration here where the skin cells really recover and work particularly well. And this process simply works better at night than during the day, when we are exposed to completely different environmental influences. Therefore, the composition of the EGF SERUM responds differently to the skin than the EGF DAY SERUM does.“ 

With the BIOEFFECT EGF EYE SERUM you can tackle classic expression lines, dark shadows or dark circles under the eyes as well as puffiness under the eyes.

  • How to use: Use the eye serum in the morning by gently squeezing the dispenser and then placing the applicator on the inner corner of the eye. Guide the ball-shaped tip around the lower and upper eyelids without applying pressure.
  • IMPORTANT: The EGF EYE SERUM is absorbed immediately and noticeably tightens the skin. For women, the serum forms an ideal basis for concealer and make-up. Our beauticians know that men also like to use this product because it can be easily used every now and then and is quickly absorbed without leaving any residue.

And if you are now wondering why you should use an eye serum in addition to the all-round EGF SERUM, our beautician will tell you why it is worth using special products:

“We have thinner skin and less fatty tissue around the eyes. With any product that is not specifically suitable for the eyes, you should not go too close to the eyes because the pH value in this region of the eye plays a major role in the products. Eye products are designed for this thin skin and contain active ingredients that intensify the refinement of wrinkles and respond to specific eye problems such as swelling.“

Who benefits from BIOEFFECT products and for whom the care is less suitable?

The products are particularly suitable for customers who value an uncomplicated care program in the evening and want to treat their skin with a product as quickly as possible. Thanks to the all-round qualities of the serums, you do not need any additional care products; you can use the serum to care for your face, neck, décolleté and, if necessary, even the eye area. Our beauticians recommend using the eye serum, as our BIOEFFECT EGF EYE SERUM experience has shown that it effectively addresses standard problems of the sensitive eye area, such as classic facial wrinkles, dark shadows or circles and eye puffiness. In addition, our BIOEFFECT EGF EYE SERUM experiences at our institute have shown that the eye serum is very often bought by men. The reasons for this are, on the one hand, that the product is absorbed very quickly and, on the other hand, that it immediately noticeably tightens and revitalizes the skin. The BIOEFFECT EGF SERUM test showed that the products are less suitable for women who need a very strong feeling of creamed skin in the evening. Such needs cannot be satisfied with 3 drops of the serum, which is why you can feel like something is missing.


Owner of the day farm, trained druggist, specialist beautician and anti-aging expert Ulrike Keller-Knobelspies tells us in an interview about her BIOEFFECT EGF SERUM experiences from the cosmetic cabin.

Question: Are BIOEFFECT products used in the cabin and what BIOEFFECT EGF SERUM experiences have you had?

Ulrike Keller-Knobelspies: We have already done treatments with customers who favor BIOEFFECT, but this in the cosmetic cabin is more suitable for a short-term treatment of perhaps half an hour to briefly improve the skin to liven up a bit. It is not necessarily the most spectacular cabin treatment because the product only develops its effect with daily, long-term use.

Question: So it is not a product that has an immediate effect, but rather takes a certain amount of time?

Ulrike Keller-Knobelspies: You can’t say that. In the cabin treatment we work with stronger peelings, very special masks and higher-dose serums that are not suitable for over-the-counter sale and must be applied by qualified personnel. In order to allow active ingredients to penetrate even deeper into the skin, we also work with ultrasound in the cabin. With the BIOEFFECT serums, customers have ideal products for daily care at home, which, after continuous use, provide results from the 3rd day onwards. week visible.

Question: So BIOEFFECT products are less likely to be offered in cabin treatment?

Ulrike Keller-Knobelspies: Yes, but we are considering whether we should offer BIOEFFECT customers a treatment followed by make-up so that they can get to know the products in the cabin.

Alternatives to BIOEFFECT

There are currently no alternatives to BIOEFFECT EGF serums on the market. In general, serums with retinol, with retinol and vitamins or pure hyaluronic B5 preparations have a quick and good effect and are therefore recommended.
