Laser treatments do stimulate the production of collagen in the dermal layer of the skin. However, it is important to select the correct laser in order to maximize this process. It is actually the thermal (heat) injury induced by the lasers which stimulates the production of collagen in the dermal layer. Therefore cold lasers and others like the erbium are not as effective.
I prefer to use fractional CO2 lasers as they combine safety and efficacy. The fractional technology minimizes the risk of pigmentation issues and scarring while still providing enough heat to stimulate collagenesis (production of collagen). Another treatment can also stimulate the production of collagen in the dermis without damaging the superficial skin (epidermis). These are radiofrequency treatments such as ALUMA and THERMAGE.
The radiofrequency energy is transferred through the skin without damaging the superficial layers, it heats the deep dermis and thus stimulates the production of collagen. In general, ALUMA does not hurt but it requires several (about 6) treatments for a good effect. THERMAGE is just a one time treatment but it can be painful (controlled with medications). Thank you.
