Frequently Asked Questions

How quickly will I see results?

Many clients notice visible smoothing within days. With continued use, lines looks progressively diminished and more refined over the following weeks.

Can CellFiller XT replace cosmetic injections?

While not a medical filler, CellFiller XT visibly plumps and smooths lines using high-performance cellular extracts rich in proteins, peptides and ezymes, boosted by hyaluronic acid and a Neuropeptide Complex-  which can complement the life of your botox,or as an-alternative for those seeking natural-looking results without injections.

Where should I apply it?

Apply to expression lines — forehead, smile lines, lip contours, and between the brows — morning and evening after your serum and before your cream.

Can I use it with makeup?

Yes. It absorbs quickly and creates a smooth, primed surface. Many clients love using it under makeup for an instant tightening effect.

Is it suitable for sensitive or mature skin?

Absolutely. It’s formulated for all skin types and especially appreciated by those 40+ who are looking to reduce the appearance of lines. 

How long will one tube last?

With regular twice-daily use, one tube typically lasts about 6 weeks.

Why does CellFiller-XT cost $260?

CellFiller-XT is formulated with CytoPep™ Cellular Extracts - a proprietary complex of  bioactive peptides and proteins that requires a specialized stabilization process  (CellControl™ Method) to remain biologically active. This technology, developed over 35  years at our Swiss laboratory, isn’t available in mass-market skincare.  

The formula is clinically tested for efficacy and safety, manufactured to Swissmedic  pharmaceutical-grade standards, and free of the fillers and silicones that make cheaper  creams feel rich without delivering results. You’re paying for 35 years of cellular research —  and for a product that loyal customers have been repurchasing, unchanged, for over three  decades.

    Key part of my skincare routine!

    I recently tried the Cellfiller-XT wrinkle filler, and I am impressed with the results. This product has a smooth texture that glides on easily and absorbs quickly into the skin.

    After using it consistently, I noticed a significant reduction in the appearance of fine lines and wrinkles. My skin feels plumper and more youthful, which is exactly what I was hoping for.

    It leaves your skin visibly smoother from the first application. I notice that the fine lines look less pronounced.

    I may be crazy but…

    I started using this a week ago and I may be crazy but I can definitely see a difference! It’s hard to believe something could work that quickly!
