Specific wavelengths of light, particularly red and near-infrared, are often employed in treatments aimed at improving skin elasticity and reducing the appearance of sagging. These wavelengths are believed to stimulate collagen and elastin production, which are essential proteins for maintaining firm, youthful skin. For example, red light therapy, a non-invasive procedure, uses low-level red light to achieve these effects.
Promoting collagen and elastin production can lead to several potential benefits, including improved skin texture, reduced wrinkle depth, and a firmer, more toned appearance. Historically, light therapy has been used to treat various conditions, and its application for skin rejuvenation has gained popularity due to its non-invasive nature and potential for positive results. Research continues to explore the optimal parameters and long-term effects of light therapy for skin tightening.
