Add defensin-molecules to your skincare regimen!

Dermatologists agree, if you do one nice thing for your skin this year - introduce it to defensin-molecules. Defensins can be incorporated into your existing skincare regimen and do not conflict or compete with other skincare. Whether it’s CHANEL or Clinique, incorporating DefenAge + Defensins can actually enhance the skincare you already know and love.


Consumer survey says that 93% of consumers who use CHANEL

skincare also like the results they see with DefenAge!

/ Survey 2019, data on file /


“Why do CHANEL users like DefenAge? – this is simple – DefenAge’s defensins multiply the effect of CHANEL, as well as other skincare. …Ironically, DefenAge skin care has no competition on the skincare market because it enhances any other skin care brands. Much like laser treatments and microneedling, the topical application of defensins causes our body to message ‘preserved,’ healthy cells to create visibly new skin. I recommend the BioSerum to my patients to activate their “skin’s memory”, triggering skin to look younger, twice a day – in the morning and evening by applying just one drop of DefenAge BioSerum over the moisturizer of their choice,”

-Board-certified dermatologist Natalie M. Curcio, M.D., M.P.H.

Why should the 8-in-1 BioSerum be layered last in a skincare routine?

The reason is because of a unique property of defensin molecules. Our bio serum contains DefenAge’s highest dose of defensins, which not only stimulate new skin, but also have shown to be effective in preventing water loss via the skin-surface’s natural “tight junction” mechanism. In other words, defensins “lock gaps” between surface cells; therefore water cannot go out, it is locked inside, but together with this – nothing goes in, meaning that if you apply any other creams or serums on top of the 8-in-1 BioSerum, their ingredients may not be absorbed.

We recommend that all skin care products in your routine be layered before the 8-in-1 BioSerum, only makeup and sunscreen should be layered on top in the morning, and nothing should be layered at night; please review the dermatologist recommendations on night skincare routines on our How-To Page.

My skin is glowing right after a week of the use of 8-in-1 BioSerum, can I increase the number of pumps for even more results?

Please be patient, more is not better. More results will not show up just because of an overuse of the bio serum. Concentrations of ingredients are very well balanced in the formula, please just follow with the recommended dosage and do it regularly: morning and night – results will not disappoint. Use one pump of the 8-in-1 BioSerum on the face and one on the neck. We also recommend exfoliating the skin regularly to see results faster – removing old cells from skin’s surface will unveil beautiful new skin; DefenAge’s gentle solution for exfoliation is the 2-Minute Reveal Masque.

Do I need to use a Vitamin C serum together with the Defensin anti-aging serum?

DefenAge’s 8-in-1 BioSerum contains a fine blend of naturally powerful anti-oxidants. We do not restrict DefenAge users form the using vitamin C serum, although we believe that it is unnecessary.

Is it true that makeup will be applied easier on skin treated with 8-in-1 BioSerum?

This is true. Due to the high concentration of defensin molecules, the skin will become smoother after using 8-in-1 BioSerum, therefore makeup will be applied easier than usual. Some consumers even say, “I do not need foundation after I started using DefenAge's bioserum.”

Why you call the 8-in-1 BioSerum an Anti-Aging Cream?

There are a few reasons. First of all, the 8-in-1 BioSerum is a perfect anti-aging cream that comprehensively addresses visible signs of skin aging on a global scale. Also, when we just built our brand and prepared to launch our products DefenAge had just one concept product, an anti-aging cream that was later named the 8-in-1 BioSerum. The 8-in-1 BioSerum is DefenAge’s concept anti-aging cream.

Is 8-in-1 BioSerum good for acne prone skin?

Yes it is. The 8-in-1 BioSerum is safe for acne prone skin, our bio serum underwent multiple safety studies that returned an outstanding safety profile. Please be sure that you use the exact quantity of the product that we recommended, and do not exceed it: 1 pump of the bio serum for entire face and 1 pump on the neck.
