When Can I Use Hydroquinone 4%?

You may begin using Hydroquinone 4% after laser procedures once the skin has completely healed. Following procedures such as the fractionated CO2 or YSGG the skin has usually re-epithelialized in about 7 days. Some individuals find the hydroquinone 4% a bit irritating and have to wait a few days longer. It is best to wait a few weeks before resuming your retinol, since this will be irritating if started too early. We typically have our patients resume their retinol about 4 weeks after their laser procedure; usually gradually by applying it every second or third day to make sure their skin is able to tolerate it. As always, sun avoidance is crucial to avoiding post-inflammatory hyperpigmentation and strict sun protection behaviors will go along way in helping to maintain your results.

HQ rarely “gets rid” of the color,, but controls it, minimizes the pigment, but rarely gets rid of it, and then only temporarily.  Sunscreen is still needed, and management of the cycles of HQ are needed.  You should not use it every day, all year.

Once your skin has healed and is not sensitive, at about 2 to 3 weeks, you can use hydroquinone.  Start using it slowly, every other day, until your skin becomes used to it and then use it daily.  Always wear a sunscreen with an SPF 60.  If you drive a fair amount, UVA penetrates through glass which may be the reason that your left side still has discoloration.
