FAQ
Is this suitable if I have a fish or seafood allergy?
This product's active ingredient is derived from salmon. If you have a known fish allergy, we recommend a patch test first or avoiding this product, and consulting a doctor or allergist if unsure.
Can I use this together with the Clueid Hatomugi or W Placenta essences?
Yes, the Pure Concentrate essences are designed to be layered — apply the thinnest, most watery texture first, then build up. If unsure of order, apply this proteoglycan essence first, followed by placenta or hatomugi essence.
