Why do we speak with sources?
The field of medical aesthetics is a discipline much discussed in popular culture, but also rapidly growing in academic data. As a patient, it is important to evaluate the information you read with its source.
The recommendations I present in this book are distilled from the American Academy of Dermatology (AAD), the European Academy of Dermatology and Venereology (EADV), the British Journal of Dermatology, JAMA Dermatology, the Journal of the European Academy of Dermatology, international sun protection guidelines, and the current melasma/hyperpigmentation literature.
Main areas of reference
Photobiology: UV spectrum, photoaging mechanisms, DNA damage, and systemic effects.
Barrier science: Stratum corneum structure, ceramide/cholesterol/fatty acid trio, TEWL, barrier repair.
Pigmentation: Melanin biology, melasma pathophysiology, treatment protocols.
Medical aesthetics: Botulinum toxin, hyaluronic acid fillers, PRP, skinboosters, mesotherapy, laser technologies.
Skin longevity: Antioxidants, peptides, growth factors, collagen induction.
Reliable sources for patients
If you wish to do your own research, I remind you that publications from physician associations, medical school-affiliated journals, and patient summaries from PubMed are safer than popular blogs.
In Turkey, the patient resources of the Turkish Dermatology Association and academic dermatology journals provide up-to-date information.
- Turkish Dermatology Association patient pages
- American Academy of Dermatology patient area
- British Association of Dermatologists
- PubMed patient summaries
- DermNet NZ (educational content)
Clinical note:I update this book every year. Because the field of dermatology and aesthetics is constantly evolving; some information that was correct in 2020 may be updated in 2026.
Selected current concepts
Some of the areas that have come to the fore in the last 5 years include: polyphenol-based antioxidant options, the effectiveness of tranexamic acid in melasma treatment, growth factors and exosome-based topicals, microbiome-based skin products, heat and moisture management technologies (cryo-care, infrared, radiofrequency).
Each of these technologies must be carefully filtered between hype and science. A device being new does not mean it is effective. Every new claim must be tested with independent, multi-center, comparative clinical studies.
How to engage with sources?
As a patient, you may want to research; this is healthy. However, reading the level of information is a critical skill: "case report" and "randomized controlled trial," "pilot study" and "meta-analysis" do not carry the same weight.
The most reliable practical approach: when looking for an answer to a question, see what at least 2-3 reputable sources say. When you come to your doctor, tell them what you have read and what questions you still have. This collaboration improves the quality of the outcome.
Essence of the chapter:Prepare a good compass before getting lost in the sea of information. Choosing reliable sources is as valuable as choosing a good doctor.
