What the current evidence supports on microneedling, PRP, melasma, acne diet, ferritin and weight maintenance — summarised without jargon.

Microneedling
Percutaneous collagen induction for atrophic acne scars

Series of 3–6 sessions consistently reported improvement in rolling and boxcar scars, with a strong safety profile in darker skin types.

PRP
Platelet-rich plasma in androgenetic alopecia

Multiple randomised studies show increased hair density versus control, with response strongest in early-stage thinning and sustained only with maintenance.

Pigmentation
Melasma management on Fitzpatrick IV–VI

Photoprotection plus topical therapy remains first line; energy-based devices are adjuncts and carry rebound risk when used aggressively.

Acne
Glycaemic load and acne severity

Low-glycaemic-load dietary patterns are associated with reduced lesion counts; evidence for dairy is weaker and individual.

Hair fall
Iron status and hair loss in women

Low ferritin is repeatedly associated with telogen shedding; correction is inexpensive and should precede procedural treatment.

Weight
Protein intake and weight maintenance

Higher protein intake during energy restriction preserves lean mass and improves satiety, supporting long-term maintenance.

Summaries are written for patients and simplified deliberately. They describe general findings, not a guarantee of individual results.
