For wrinkle reduction or face lifting effect, chemical adjustment (cross-linking) is needed to improve the duration of HA effects.
HA is hydrophilic and biocompatible, but highly dissoluble. Non Cross-linked HA is quickly degraded when applied to the skin = no effects.
On average, HA production in the body starts to decrease at the age of 18-20. At age 40, the production rate decreases by 50%, compared to the rate of the 20s.
