I have large brown spot on cheek and have rosacea in same area. Is there any treatment that will not affect my rosacea?

The Vbeam laser and Limelight treatments can both improve the rosacea and the brown age spots. Best, Dr. Karamanoukian 

Actually you want a treatment that will help your age spots AND your rosacea. IPL, and BBL treatments as well as tuneable dye lasers work well for these conditions.

Various laser can work in both conditions.The q switched yag in the 1064 wavelength can work on the brown spot and the 532 wavelength can improve the appearance of rosacea. Other option include pulse dye laser or Ipl.

You can absolutely target one specific spot. So what
should you do if you have brown spots? First, prevention! Keep your skin
healthy and protected with a good sunscreen. Second, treat the spots. Age spots
can be lightened or even removed with special in-office treatments. I have also
developed topical skin care products which you can use at home to help reduce
the appearance of brown spots. I’ve developed a special regimen for brown
spots using these products specifically for the in-home treatment of brown, age
and sun spots. For more pervasive brown spots, a visit to the office for laser
treatments will help eliminate these spots.

The type of treatment depends on  your skin type, if the brown spot is raised or flat, and the type of rosacea you have. Intense pulsed light/IPL is a good option for flat sunspots in the setting of vascular rosacea or broken blood vessels. The IPL procedure targets both pigment and redness in the skin. IPL can either be targeted to a specific area, or can be used as a pan-facial treatment. It can take up to 1-3 treatments depending on the amount of pigment and redness present. If the brown spot is raised you might need an alternative type of treatment. If you have broken skin or active acne lesions of rosacea in the area of the brown spot you may want to hold off on treatment until the rosacea is under better control. Light chemical peels can also be done to lighten brown spots however a series of light peels may be required. I would recommend being careful with over the counter anti-aging and skin brightening creams in the setting of rosacea- many formulations can be irritating and can aggravate the underlying rosacea. I would see your dermatologist to discuss how to better control your rosacea and what would be the best option for you. 

Brown spots maybe flat or slightly raised. If they are flat, certainly IPL can help. The use of Q switch laser can also treat this spot, but yes, your rosacea may flare up after QSL as it causes redness before fading. This is not a problem if you undertake medical treatment to help reduce rosacea flares, additionally lasers such as V BEAM can be used to treat BOTH redness (rosacea) and brown spots. The V BEAM has a special setting for brown spots. If this spot is raised, I would use an erbium laser. This will flatten the spot, your skin will heal within 8 days, then I would use V Beam to prevent a flare up of rosacea. Infinite combinations are possible. CheersDr Davin LimLaser and cosmetic dermatologistBrisbane, Australia. 

There are several options for treatment. Advanced skin cares with skin lighting
properties can often resolve sunspots or lighten them significantly and should
not affect Rosacea. If successful this
will usually require several 4-6 months.
The other treatment could be spot treatment with chemical peels or
lasers. Once gone the absence of the spot may leave a whiter spot (normal skin
where no Rosacea exists). Before
initiating treatment it is most important to make sure what you are treating.
There are many types of brown spots most benign but some are malignant
(cancerous) and treatment only delays the correct method of treatment to
remove. See your Board certified Plastic
Surgeon or Dermatologist for a quick check.
