Eczema, Também conhecido como atopic dermatitis, is a chronic skin condition that causes inflammation, vermelhidão, itching, e secura. Affecting millions of people worldwide, eczema can significantly reduce quality of life and be difficult to manage with conventional treatments alone. Nos últimos anos, Terapia com luz vermelha (Rlt) has emerged as a promising alternative or complementary treatment. But how effective is it for eczema?
Let’s explore how red light therapy works and its potential role in managing eczema symptoms.
O que é terapia com luz vermelha?
Terapia da luz vermelha usa low-level wavelengths of light-normalmente entre 630nm e 850nm—to penetrate the skin and stimulate cellular activity. It’s a painless, non-invasive therapy that encourages healing, reduz a inflamação, and promotes collagen production.
This form of therapy is commonly used in dermatology for:
- Rejuvenescimento da pele
- Cicatrização de feridas
- Tratamento da acne
- Psoriasis and rosacea
- Joint pain and inflammation
How Red Light Therapy May Help Eczema
1. Reduz a inflamação
Inflammation is at the core of eczema flare-ups. Red light therapy helps calm the immune response by reducing inflammatory cytokines and oxidative stress in skin cells. Isso pode relieve redness, inchaço, and itching.
2. Strengthens Skin Barrier Function
RLT supports the health of skin cells and improves blood circulation, which may help restore the skin’s natural barrier. A healthy barrier prevents moisture loss and blocks irritants—both crucial in managing eczema.
3. Promotes Healing and Tissue Repair
By stimulating ATP (energia celular) production and collagen synthesis, red light therapy accelerates tissue repair. Isso pode ajudar heal cracked, flaky, or irritated skin faster and reduce the chances of secondary infections.
4. May Reduce Itching (Pruritus)
Early research suggests that red and near-infrared light can help calm nerve activity and reduce itching, one of the most distressing eczema symptoms.
O que a pesquisa diz?
Although more large-scale human studies are needed, early clinical evidence is encouraging:
- UM 2013 study showed that red light therapy significantly reduced itching, scaling, and skin thickening in patients with atopic dermatitis after several sessions.
- UM 2021 review noted that low-level light therapy could modulate inflammatory responses and improve skin integrity in inflammatory skin diseases.
- Dermatologists have reported successful use of RLT as a complementary treatment for eczema, especially in mild to moderate cases.
Como usar a terapia da luz vermelha para eczema
- Comprimentos de onda: 630–660nm (luz vermelha) e 810–850nm (infravermelho próximo)
- Tempo de tratamento: 10–20 minutos por sessão
- Freqüência: 3–5 times per week for best results
- Aplicativo: Direct the light at affected areas, keeping the device a few inches from the skin

⚠️ Always check with your dermatologist before beginning any at-home light therapy, especially if you are using prescription creams or steroids.
O que esperar: Antes e depois
| Before RLT | After Regular RLT Use (4–8 Weeks) |

| Constant itching | Less itching and irritation |
| Cracked, flaky skin | Mais suave, more hydrated appearance |
| Frequent flare-ups | Longer periods of remission |
Results vary by individual, but consistency is key. RLT works best when used regularly over time and in combination with proper skincare and medical guidance.
