Leading scientists in human protein based biotechnology and dermatology have developed the BIOEFFECT EGF Serum, the best skin care product available today. Great emphasis was placed on developing a new kind of skin care product that is EFFECTIVE, SAFE AND PURE. The serum contains no preservatives, colorants, fragrances or other unessential chemicals that can cause harm to the skin. BIOEFFECT EGF Serum also contains no known allergens, giving you complete peace of mind that you can use the serum without it causing any irritation, redness, or swelling of the skin.

We understand that it's important to look after your skin, whether you're young or old, male or female. BIOEFFECT has been specifically developed to help you manage and maintain your skin effortlessly, giving you the beautiful radiant skin you deserve without having to spend hours on a daily/nightly regime. BIOEFFECT isn't just a simple moisturiser that's been quickly put together, it's taken time and research to make sure everything is perfect and that this serum will work on all kind of skin. Through extensive testing, we've finally mixed together the best natural skin care product available on the market today, a product that ensures high quality results, not just as a short term result, but as a product with long-lasting benefits as well. 

The opportunities are endless with BIOEFFECT; scientists are working on extensive R&D for the development of new and revolutionary skin care products, and also on a range of other health and beauty products, including hair care regeneration. With 130 different cellular activators in the pipeline, and a clear understanding of what people look for in the best natural skin care products. Sif Cosmetics aims to set a new standard for what consumers should expect from products in terms of efficacy first in the skincare market and then in the health and beauty care category more broadly.
