Clinical research

The health effects of sunlight are supported by decades of research - Solius is built on that science. Chat with Sunny to explore the studies behind the science.

Skin Health

Evidence suggests that UVB light, like the Solius spectrum, may calm overactive immune responses in the skin, reduce inflammation, and normalize skin cell turnover. By working directly at the skin level, UVB light supports clearer, healthier-looking skin in ways topical and oral treatments alone may not achieve.

Potential benefits

  • Slows rapid skin cell growth by influencing cellular activity in the epidermis, helping reduce thickened plaques and scaling associated with conditions like psoriasis.

  • Reduces skin inflammation to ease redness, itching, and discomfort.

  • Modulates immune activity in the skin, helping calm overactive immune cells involved in chronic skin flare-ups.

Photodermatology, Photoimmunology & Photomedicine

Cette étude de synthèse systématique a conclu que la photothérapie à bande étroite est efficace pour le traitement du psoriasis chez les patients ayant une peau de couleur. Ces conclusions sont importantes, étant donné que l'évaluation et le traitement des affections dermatologiques sur les peaux de couleur est un domaine sous-étudié. Parmi les études évaluées dans cette synthèse, 70,5 % des patients ont atteint le PASI75, un critère de référence pour l'efficacité du traitement du psoriasis par lequel les patients constatent une réduction de 75 % de leur score PASI, et toutes les études ont démontré une amélioration statistiquement significative du PASI après le traitement.

Journal of Multidisciplinary Healthcare

Cette étude se penchant sur l'impact de la supplémentation en vitamine D sur la cicatrisation des plaies chroniques a révélé que les participants du groupe de supplémentation ont bénéficié d'un temps de cicatrisation moyen plus rapide que ceux du groupe témoin. Le groupe de supplémentation a également montré des améliorations quant au taux de réduction de la surface des plaies et au taux de réduction de la profondeur des plaies par rapport au groupe témoin.
