Even after reaching the recommended number of sessions, the results of red light therapy (RLT) are not permanent. As skin cells change, you may start to see signs of aging again and acne breakouts. Although most people report fantastic results, they are not long-lasting. LED light therapy, especially LED light masks, should not be considered the only solution to all skin problems, nor a substitute for a doctor's appointment.
Think of it more as a supplement to your skincare routine. The main objective of the study was to improve subjective complexion and skin feel. Volunteers were asked to specify their level according to the statements in the questionnaire by marking a position along a solid black line between two endpoints measuring 10 cm, which served as a visual analog scale (VAS). Secondary objectives were the improvement of measurement parameters using a DermaLab Combo (Cortex Technology, Hadsund, Denmark), a computer-aided skin diagnosis system equipped with a high-resolution rotating ultrasound sensor probe (20 MHz) for the determination of changes in the intradermal collagen density, measured as a collagen intensity score (CIS).
A Primoslite digital stripe projection system (GFM Messtechnik, Berlin, Germany) was used to measure the objective arithmetic roughness (Ra) of the skin surface in the periorbital region. Experts agree that you're likely to see some skin improvement effects with RLT, but as with most skin rejuvenation treatments, these results will be temporary. That's why it is recommended to use it regularly, whether in an office, a spa or at home. In other words, if you're looking to achieve smoother skin and reduce fine lines, you'll need to keep up your sessions so that each one supports and builds on the other; then, over time, usually within weeks or months, you should start seeing noticeable changes. Units 3 and 4 were equipped with low-pressure gas-discharge fluorescent lamp tubes that provided a spectral emission peak predominantly within the range of 611-650 nm, referred to as RLT.
Some authors emphasize the importance of different wavelengths for optimal results. In our study, differences between RLT and ELT treatments in clinical outcome and patient satisfaction were not significant, indicating that both light sources were proportionally effective in terms of study objectives. We hope that this article has answered your questions about RLT and its potential benefits. RLT, either alone or in combination with other treatments such as blue light therapy, is a potentially effective treatment for acne vulgaris. Many people use RLT because they have peripheral neuropathy and experience pain reactions like needles pinching their skin.
Red light is natural and can penetrate deep into the skin where cells can absorb and use it. The problem with exposure to sunlight is that it is accompanied by exposure to ultraviolet (UV) A and UVB rays which can cause other skin problems over time. So how does red light work? “Red light waves stimulate mitochondria which is the energy center inside every cell. Pulsed waves provide short bursts of high-power light of nanoseconds duration delivering more light energy deep into the body without heating the tissues. Dose-to-wavelength ratio for ELT and RLT light sources normalized to the 611—650 nm spectral range. In conclusion, red light therapy is thought to act on the “power plant” of the body's cells called mitochondria and can provide temporary improvements in complexion and skin feel when used regularly.
However, it should not be considered as a substitute for medical advice.
