Anti Aging Laser Treatment and Therapy

On the other hand, some products may be too good to be true. Skin creams, lotions, and moisturizers are not necessarily effective in preventing the onset of visible aging. The skin is a remarkable barrier and can prevent most creams and lotions from penetrating to deeper skin layers. In fact, most over-the-counter topical products create a thin layer on the skin and then slowly rub off as you go about the activities of your day. Few topical products actually penetrate and lock moisture into skin. At best they prevent moisture from evaporating off the surface of skin in a manner not unlike plastic wrap. While this may be temporarily plumping for skin, it does not have the long-lasting effect that users want.
Certainly high intensity lasers have been effective at wrinkle reduction. These devices use highly powered and concentrated light energy to ablate (burn) wrinkles from the skin. They can be used to destroy the top layers of the skin creating smoother skin (after the swelling and redness goes away). There is no doubt that high intensity lasers can ablate skin and wrinkles, but they are far from harmless. The skin is mechanically changed by this process. This skin suffers first degree burns as a result. Because of the intensity of the energy used, high level lasers can only be used by a medical professional. This makes treatments relatively expensive. What is more, the wrinkles eventually come back, which means more professional treatments are necessary (and more money).
Low level laser therapy, or cold lasers as they are sometimes called, strikes an interesting balance between effectiveness, safety, and affordability. In contrast to high intensity lasers, low level red light therapy does not change the surface structure of the skin. The energies used in this approach are much lower. The light does penetrate the skin, even at low energy, based on the wavelength of the laser used. Red light (wavelength ~650 nm) does not penetrate too deeply, but blue light (~400 to 420 nm) penetrates down to the dermis (deep layer) of skin. The dermis is where active skin cells are mainly located (most of the skin cells you see on the skin’s surface are actually dead!)
Because of the low energy output used in low level laser therapy, the treatment is remarkably safe. The technology has been cleared by the FDA based on the safety and effectiveness of the product. NOTE: Not all devices have been cleared by the FDA for low level laser therapy nor has every wavelength of light. It is important to use devices that have been cleared by the FDA. In general, low level laser use is associated with very few side effects or complications. When used properly, low level lasers are extremely safe.
Perhaps there is no better evidence for this safety than the fact that low level laser use is available at home. Non-medically trained people, including patients, can purchase and use personal-use devices (though some states may prohibit non-trained and non-licensed people from using the devices on others). The availability of home-use low level lasers for anti-aging speaks to the remarkable safety profile of the device and technology.
Two devices from Laser Therapeutics provide safe, affordable, low level light energy for home use. The Beurer SL30 Softlaser operates at 660 nm (red light) which means that it can penetrate to the active layers of the skin. However, the light energy is non-invasive and painless because it delivers this energy at low levels. A newer device, Laser Therapeutics SL50 Cluster Laser is a recent upgrade to the SL30 which provides both red and infrared energy to the skin with a comfortable massaging head. Low level light energy can be delivered in either continuous wave or pulsed frequencies to reduce the appearance of fine lines, wrinkles and striae (stretch marks).
On the other hand, just because low level laser is available at home for anti-aging use does not mean that it is too weak to be useful. On the contrary, low level laser treatment simply improves the look of skin by a different mechanism, not a less effective one. As was mentioned, high energy lasers ablate or destroy tissue to remove wrinkles. Low level lasers do not change the visible structure of the skin immediately. They do not burn the skin or cause inflammation. The low level laser stimulates living cells within the skin. The light energy tells the cells to start producing the proteins and growth factors that make the skin firm yet smooth.
Low level laser therapy tends to cause the skin to contract after treatment. This can be seen in wound healing,(1) but also applies to anti-aging uses as well.(2;3) What appears to occur is that low level laser ight therapy stimulates fibroblasts (a type of skin cell) to produce collagen and other proteins and peptides that naturally occur in the extracellular matrix. In other words, the low level laser energy stokes up the same cellular processes that were used when skin was soft and smooth but has diminished with age. Instead of mechanically removing wrinkles from the surface, low level laser energy makes the body rejuvenate itself from within.
Perhaps the greatest benefit to patients is that because low level lasers are safe, effective, painless, non-invasive and drug-free. They are also more affordable than other techniques and procedures long term. By using low level laser at home for anti-aging, trips to the dermatologist or plastic surgeon are a thing of the past. Ablative techniques, dermal fillers or botulinum toxin will need to be repeated by a professional. With an at home low level laser, anti-aging treatment can be done when needed to maintain optimum results (up to a maximum amount per day). The only cost is the low level laser therapy device—the “labor” is free!
