However, always consult with the skincare professional who performed the treatment before applying any product post-procedure.

 Q106: What's the role of hyaluronic acid in hair care?

 A: HA can be found in some hair care products due to its hydrating properties. It can help maintain scalp health, promote shinier hair, and reduce hair breakage by retaining moisture in the hair strands.

 Q107: How does hyaluronic acid compare to glycerin in skincare?

 A: Both HA and glycerin are humectants, meaning they attract moisture. While they serve similar moisturizing functions, HA can hold up to 1,000 times its weight in water, making it particularly effective at hydration.

Glycerin, on the other hand, is derived from plant-based oils and is also an effective moisturizer but may feel slightly heavier than HA on the skin.

 Q108: Can hyaluronic acid serums be applied around the eyes?

 A: Generally, yes. Due to its hydrating properties, HA can be beneficial for the delicate skin around the eyes.

However, always ensure that the specific product is formulated to be safe for the eye area or consult with a dermatologist.
