Perfect for makeup
I am a huge fan of the regular EGF serum, so I wanted to try the Day Serum to see if it made a difference to use the day/night combination. This is PERFECT for underneath makeup - it gives you all the hydration of the regular serum but is an even better canvas for makeup.
Totally soothed my redness, and I didn't need any primer to keep my skin from getting oily. THIS IS SO GOOD. The new packaging also feels like it has more product, which is great because I tend to be a bit heavy handed with hydration.

Not too good
I recieved this as a sample and for the retail price of it i wasnt that impressed really. It made my skin feel quite sticky and didnt sit nicely underneath my moisteriser and made my make up look weird. Its a shame as its a luxary product but i wouldnt spend my money on it

It works!
I have been using the EGF Power Serum
for months so when the Day Serum was released, I was reluctant to add another product to my routine. I am, however, happy I did try the sample that arrived with my last order because I found the new Day Serum to be perfect! It glides on, sinks in quickly and gives my skin extra hydration. I will continue to use the Power Serum at night which is a win-win for my skin & pocketbook.

Wonderful under makeup
I’ve been using this serum in the morning for nearly a year. It has really helped my skin, especially in terms of the texture and general prep for makeup. The consistency is thicker and more similar to some silicon based primers. One pump is all you need for full face application.

Awesome Product!
I absolutely love the Bioeffect EGF Day Serum. I use it before I put my sunscreen on and it is the perfect base layer as it prevents the sunscreen from streaking or caking on my face. It moisturizes my skin allowing for a flawless application. The Day Serum is an easy addition to my daily skin care routine that evens out my skin tone, reduces the appearance of my wrinkles, and it doesn't feel heavy on my skin. I highly recommend it.

Incredibly hydrating
The texture of this serum is exceptional. I received a travel size in the Spring beauty box. I use it when my skin feels very dehydrated. It plumps, smooths texture and is one of the most hydrating products I have ever used. It took sticky, sinks in well and is a great base for makeup. It is expensive, however, if this is within your budget I highly recommend this.

Firming
Have been using this for a couple of weeks and can see a difference already. This is a lovely texture to apply. Originally I used this on it’s on in the mornings however was not quite hydrating enough so now apply my moisturiser after this product.
I definitely feel this product has firmed my skin Plumped out my skin.
