Head-to-Head Comparison: HA7X Multi-Molecular Hydrator Serum vs. SkinMedica® HA5 Rejuvenating Hydrator

HA7X Hydrator bests HA5 | 29 of the same ingredients + Neurophroline | Half the price

HA7X is the first direct competitor to award-winning HA5 Rejuvenating Hydrator by SkinMedica®, a component of Allergan, Inc.

HA7X includes 29 of the same primary ingredients in HA5, including Vitis Flower Stem Cell Extract, Peptide Complexes, and Sea Polysaccharides from French Polynesia.

But we didn't stop there: HA7X includes two additional, cutting-edge hyaluronic technologies (for a total of seven); HA5 only contains five.

HA7X is also the first U.S. product to contain benefits of Gold award-winning Neurophroline™ targeting stress, pollution, and cortisol.

Yet with these new actives, HA7X is about half the price as SkinMedica’s version.

HA7X works for all skin types, and is the perfect complement to any skincare regimen to prevent and combat the signs of aging.

Chronobiology: Does skin have a circadian rhythm?

Best time of day to apply Reviv Serums

The skin goes through different phases in 24 hours. During the day, it defends itself against external aggressions like the wind, the sun, the cold, or pollution. At night, it regenerates.


It was evidenced that the highest number of cell divisions occurs between midnight and 1am, and the lowest between 12pm and 1pm. The skin's blood flow is at its maximum between 11pm and 4am, which makes it possible to provide nutrients and remove toxins. And it is between 7pm and 11pm that desquamation on the superficial stratum corneum is the most important.

In addition, the skin has receptors for melatonin which, on top of their role as circadian synchronizers, are excellent at trapping free radicals. In the late 1990s, researchers highlighted the existence of the "Clock" gene as a central regulator for monitoring the circadian clock.

According to Neil Astles, Marketing Manager for biofunctional actives at Ashland Specialty Ingredients, "more than 20% of the expression of a tissue's genes depends on circadian regulation".

"In Asia, it is said that the first three hours of sleep, called 'Golden Time', are the most important for the skin. In Korea, there is also an expression, meaning 'well-slept face', to refer to a beautiful face. It is conveyed by the face of a sleeping woman", explains Florence Bernardin, expert in Asian cosmetics trends and founder of the Information & Inspiration marketing intelligence firm.
