Frequently Asked Questions
Q. When is the best time to take Firm Response?  
A. Firm Response can be taken at any time of day.
Q. Can I mix it with water to drink? 
A. Firm Response can be mixed with water if you’d prefer to drink it, however suggested usage is direct to mouth.
Q. Does the powder have a taste?
A. It is orange flavored.
Q. What does AGE Blocker® mean?
A. Firm Response features an Anti-Glycation Complex called AGEs Blocker®, made from three key ingredients (Korean Mint, Goji Berry and Fig). Together, these ingredients help protect your skin from glycation, supporting firmer, smoother, more youthful-looking skin.
Q. What Type of Collagen is in Firm Response Formula?
A. Firm Response formula contains hydrolized marine Collagen Naticol®, derived from Tiliapia fish skin sustainably sourced from France. In the case of Naticol® BPMG, food-grade protease enzymes break down native collagen into low molecular weight peptides (around 2 kDa), including dipeptides and tripeptides. This results in a highly bioavailable form of Type I collagen-the primary collagen found in skin-allowing for improved absorption and delivery of bioactive peptides that can support the body's natural collagen production, skin firmness, and elasticity, even at lower dosages compared to standard collagen.
Q. What are different hydrolyzed processes and which one is the best? 
A. Collagen can be hydrolyzed using different processes, but not all deliver the same quality or efficacy. Acid, alkaline, or heat-based hydrolysis  break  collagen down quickly but in an uncontrolled way, often destroying functional peptide structures and resulting in mostly free amino acids with lower biological activity. In contrast,  Naticol® BPMG uses  enzymatic hydrolysis, a precise, food-grade process where specific protease enzymes break collagen from fish skin into targeted low molecular weight peptides (~2 kDa), including bioactive dipeptides and tripeptides. This controlled process preserves functionality and ensures: 
- Higher bioavailability  (better absorption in the body)  
- Bioactive peptides  that can signal collagen production  
- Consistent, high-quality peptide profile 
As a result, enzymatically hydrolyzed collagen like  Naticol® BPMG is more efficient and effective than standard hydrolyzed collagen, allowing for meaningful benefits even at lower doses. 
Q. What do the Ceramosidesâ„¢ in Firm Response do?
A. As we get older, our natural ceramide levels go down and as a result, the skin barrier becomes weaker. Firm Response uses Ceramosidesâ„¢, which are plant-based ceramides from wheat extract, that are fast-acting and rich in phytoceramides. Once ingested, Ceramosidesâ„¢ are digested and absorbed, allowing their lipid components to help replenish and support the skin's natural ceramide levels from within. They help to maintain skin barrier function, improve skin moisturization, reduce roughness, improve skin smoothness and elasticity and reduce fine wrinkles.
Q. What does the Hyaluronic Acid in Firm Response do?
A. Hyaluronic acid is a natural molecule in your skin that holds water, keeping your skin hydrated, plump, and smooth. Think of it like a sponge - it attracts and retains water in the skin.
Q. How does Vitamin C help Collagen production?
A. Vitamin C helps fibroblasts, the skin cells that make collagen, carry out the chemical steps needed to build strong collagen fibers. It also helps protect the long-lived collagen from damage caused by oxidative stress. In this way, it supports both collagen production and collagen quality. Additionally Vitamin C helps protect skin cells from free radical damage caused by UV exposure, pollution and stress.
Q. Is Firm Response Gluten-Free?
A. No, Firm-Response is not gluten-free.
