Hydrophilic injection mainly uses negative pressure to inject hyaluronic acid, botulinum toxin, tranexamic acid and other injections into the superficial dermis, so as to achieve the effects of hydration, fine lines, whitening and so on. If the patient has more facial redness spots, photorejuvenation is more effective. If the patient has more facial fine lines or dull skin, the effect of photorejuvenation and hydrafacial injection is similar. Photorejuvenation and hydrafacial injection have their own specialties and focuses. If you are willing to be treated, it is recommended to go to a regular medical institution for consultation, and which one should be done according to the patient’s own skin condition under the guidance of a professional doctor.
