What is red light therapy? Discover how it reduces hyperpigmentation, boosts collagen, and calms inflammation for even skin tone.
Skin conditions can strongly influence self-esteem. One of the most common is hyperpigmentation. We’ve all heard the term, but what does it mean?
Hyperpigmentation produces dark patches on the face, hands, and other sun-exposed areas. These spots vary in shape, size, and color—from light brown to black—and can be hard to conceal.
The main types are:
Pigmentation spots (age spots) arise after years of sun exposure. They usually appear as small, darkened areas on the face, hands, or arms.
Melasma or chloasma, often called the “pregnancy mask,” affects up to 90 % of pregnant women. Hormonal shifts during pregnancy or with contraceptive use can trigger large, irregularly shaped facial patches.
Post-inflammatory hyperpigmentation remains after skin injuries heal. It is common after acne and may also follow cosmetic procedures such as dermabrasion, laser therapy, or chemical peels.
Moles, scars, sun (actinic) keratoses, and skin cancers can darken too, but they are not classified as hyperpigmentation.
Hyperpigmentation develops when melanin—the pigment that colors skin, hair, and eyes—is overproduced in certain areas. Triggers include ultraviolet exposure, genetics, aging, hormones, skin trauma, and occasionally underlying disease.
Limiting sun exposure, wearing protective clothing, and applying broad-spectrum sunscreen (UVA/UVB) may reduce the risk and prevent existing spots from worsening.
Several options exist for managing hyperpigmentation; red light therapy is one approach being studied. Red light can be absorbed by skin-cell mitochondria, potentially boosting adenosine triphosphate (ATP) production. Higher cellular energy may support faster skin repair and gradual normalization of pigment.

In turn, collagen levels may rise, helping to ease other skin conditions such as rosacea. Elastin levels can also increase, supporting a firmer, more youthful appearance.
Although many options exist for hyperpigmentation, a gentle yet effective approach is often preferred. Luna’s red-light therapy devices are designed to address several skin concerns, including hyperpigmentation. They are MDA-certified and cleared for cosmetic use, aiming to support safe, consistent care.
