Final answer:
Heparan Sulfate Analog (HSA) created by SENTÉ is a master hydrator. It is designed to replenish skin hydration effectively as the skin ages, making the correct answer C) Hydrator.
Step-by-step explanation:
The SENTÉ product described in the question contains Heparan Sulfate Analog (HSA), which is designed to be a master hydrator.
The proper term to fill in the blank would therefore be "C) Hydrator". Unlike typical moisturizers, which may contain water for temporary hydration, occlusives to prevent moisture loss, or humectants to draw water into the skin, HSA works to replenish what the skin naturally loses with age, thereby maintaining hydration at a more effective level.
The role of HSA as a hydrator is to aid in the skin's hydration process more effectively than traditional hydrating components by mimicking the natural actions of the skin, reinforcing the skin's barrier and providing deeper hydration.
