Hyaluronic acid gel can repair skin and prevent skin scarring when it is used in skin injury, but its auxiliary effect on repairing existing scars on skin surface is not obvious. Hyaluronic acid gel has anti-inflammatory and antibacterial effects and can repair skin damage. Therefore, applying hyaluronic acid gel when the skin is just damaged can eliminate the inflammation at the bottom of the skin and quickly repair the skin damage, thus preventing the scar from appearing on the skin surface. However, for the healed skin scar, hyaluronic acid gel can only play a certain repair role, but the overall repair effect of the scar is not obvious.
Hyaluronic acid gel has anti-inflammatory and antibacterial effects, so it can improve the reddish acne and acne marks on the face to a certain extent, but it is not obvious to improve acne marks for many years. Hyaluronic acid gel is mainly used to replenish water, diminish inflammation and resist bacteria, but its effect in improving melanin deposition is relatively weak.
Hyaluronic acid gel does have certain benefits to the skin, but it is not omnipotent. Everyone should use it reasonably.
