Common questions
- How often is the Lumen Ritual journal updated?
- New articles are published regularly and existing ones are revisited whenever guidance or formulations change. Every post shows its author and last-updated date at the top so you can see how current the advice is.
- Who writes these skincare articles?
- Maria Alejandra writes and reviews every article on the site. Each piece cites the reasoning behind its recommendations and carries a medical disclaimer, because routine advice is not a substitute for a dermatologist's diagnosis.
- Which article should I read first?
- If you are starting from zero, read the skin type guide, then the layering order article. Once your base routine is stable, move on to the ingredient explainers for the active you want to add.
- Are the products mentioned in these articles sponsored?
- No. Products are chosen on formulation and track record, never on payment. Some retailer links earn a commission at no cost to you, and that never changes which product is recommended.
