Red light at 633nm penetrates the skin at a relatively shallow level, making it ideal for targeting surface-level tissues such as the skin, hair follicles, and small blood vessels. Some of the most widely recognized benefits of 633nm red light therapy include:

Skin Rejuvenation: Red light at this wavelength stimulates collagen production, which helps reduce the appearance of fine lines, wrinkles, and scars. Clinical studies show that 633nm red light increases fibroblast activity, leading to improved skin texture and elasticity and is known to treat many different skin issues including age spots, hyperpigmentation, and psoriasis

Wound Healing: Studies have demonstrated that 633nm light therapy can accelerate the healing of superficial wounds by enhancing cellular metabolism and reducing inflammation. This wavelength boosts ATP (adenosine triphosphate) production, which provides the energy necessary for tissue repair.

Hair Growth: Red light therapy at 633nm has shown significant promise in treating hair loss. This wavelength stimulates blood flow to the scalp and activates hair follicles, promoting new growth and improving hair density. Research indicates that consistent exposure to 633nm light increases the production of keratinocytes, the cells responsible for hair growth.

Anti-inflammatory Properties: Inflammation is a key factor in many chronic skin conditions like acne and psoriasis. Red light at 633nm reduces the activity of inflammatory mediators, helping to calm irritated skin and prevent breakouts.
