Idk but I think you kinda confuse between AHA and HA, HA is to hydrating your skin, so it won't dry your skin, instead it will make it more plump and moist. Whereas, AHA could dried your skin because it supposedly become a exfoliating agent or drying your acne kind of stuff.
@@malaikat3748 actually, HA does dry out the skin if used in dry environment. It's gonna suck all the moisture from within the skin instead of the air 'cos of less moisture in the air. Just make sure u have like a humidifier in your room, it should be fine
