Skin becomes very dehydrated after using hydroquinone 4%?

Hydroquinone is a staple in a rejuvenative skin program. If you are getting dryness during application, you may want to use a ceramide based moisturizer such as Elevase Moisture Booster to help strengthen the skin's natural moisture barrier function. Best, Dr. KaramanoukianLos Angeles

Hi thanks for your query.A detailed  skin care regime you are currently on will be more helpful to answer your concern,Hydroquinone causes more of irritation than dryness .HENCE if you feel it dehydrates your skin apply a bland moisturiser and then apply hydroquinone based creams,Most important is you should not use it indefinitely as they do cause long term side effects.Do consult a board certified dermatologist and slowly wean it and switch over to non hydroquinone based creams ,

To fully understand your dryness, I would need to know your entire skin care regime.  Sometimes, dryness is a necessary reaction that you have to go through to create healthy skin.  Hydroquinone is a strong topical medications and I would not vary from the instructions you were given.  If you are having issues, I would go back to your clinician.I hope this helps.
