Long term effects from Lasers used to diffuse redness?

People tend to attribute long term changes in their skin to treatments they had a long time ago. IPL and lasers are great treatments to tamp down redness in the skin. When done by an experienced person, they are very safe. The real risks of both are burns, scarring, hyperpigmentation and hypopigmentation. Any of these can be terrible long term. But they happen soon after treatment. 
As you age, your skin loses collagen and elastin, the skin thins, fine lines appear and you lose both bone and fat. This is not caused by lasers or IPL, this happens to everyone as they age. Whatever treatment you have today, in 5 years you will look 5 years older if you do nothing more to treat/care for your skin. 

IPL is an effective treatment for rosacea and is recommended by most dermatologists in conjunction with topical rosacea medications. IPL done properly will help reduce redness, improve pore size, even skintone, reduce hyperpigmentation, and reduce fine lines. Generally three treatments one month apart are needed. You should not be tan and should avoid the sun after treatment. IPL will NOT reduce skin elasticity, add fine lines, or increase fat loss. The skin is always aging but aging can be slowed and it's appearance improved with effective skin treatments.
