BLU-U Blue Light Therapy

Skin Rejuvenation

Sun spots, acne control, smoother texture and more even skin tone.

When Levulan® Kerastick Topical Solution is applied to Grade 1 or 2 sun spots, the solution is absorbed by the cells where it is converted to a chemical that makes the cells extremely sensitive to light. When the cells are exposed to the BLU-U®, this light causes reactions which destroy the AK cells.

The BLU-U is a unique blue light that can kill the P. acnes bacteria in your skin. If you’re looking for an alternative to medications or antibiotics to treat your acne, it may be just what you need. The BLU-U is not a laser. Lasers deliver light as coherent beams, while the BLU-U delivers incoherent light scattered over a larger area.

Blue Light Therapy | Sun Spots

Photodynamic Therapy using the BLU-U Blue Light Photodynamic Therapy Illuminator is an advanced 2-step treatment for minimally to moderately thick Grade 1 or 2 AKs (sun spots) of the face or scalp. This therapy is unique because it uses a light activated drug therapy to destroy AKs.

Actinic Keratoses (AKs) are rough-textured, dry, scaly patches on the skin caused by excessive exposure to ultraviolet (UV) light, such as sunlight. They are often referred to as “sun spots” and they occur most frequently on sun exposed areas such as the face, scalp, ears, neck, hands and arms.

They form on the outermost layer of skin and they can range in color from skin toned to reddish brown. They can also range in size from as small as a pinhead to larger than a quarter. More than 10 million Americans have AK lesions, with the majority occurring primarily in fair skinned individuals.

Blue Light Therapy | Acne

Not exclusive to teenagers, many young adults have trouble with acne that is hard to control. The BLU-U Blue Light Therapy – using light without drugs or antibiotics – may be something to try if you’re looking for an alternative to medications or antibiotics.

What is Blue Light Therapy? The BLU-U is a unique blue light that can kill the P. acnes bacteria in your skin.

Treatments are simple – you sit with your face close to the light for a short time at a schedule set up by Dr. Lin, approximately a 16-minute session about once or twice per week. The treatments may go on for five weeks or so.

It’s safe, it’s not hot, it’s not painful. After some weeks, the blue light helps control your acne.
