UVA protection for pigmentation and sunscreen SPF
UVA Protection for Pigmentation: What PA++++ and Boots Stars Really Mean | Expert Dermatologist Guide

SPF 30 vs SPF 50 vs SPF 100 sunscreen comparison
SPF 30 vs SPF 50 are often compared with SPF 100, but these numbers do not simply represent percentages of UVB protection.

SPF 30 vs SPF 50 are commonly compared when choosing sunscreen, but these numbers do not simply represent percentages of UVB protection. This explanation is convenient, but it can make the differences between sunscreens appear smaller than they really are. SPF works as a biological protection factor based on the ultraviolet dose needed to produce […]

Dermatologist examining a patient for skin signs of internal disease
Skin Signs of Internal Disease: When a Skin Problem Needs Further Investigation | Expert Dermatologist Guide

Endolift vs Fractional CO₂ Laser for Skin Tightening: What the Evidence Shows | Expert Dermatologist Guide

Patients comparing Endolift vs fractional CO₂ laser are often told that both treatments stimulate collagen and tighten skin.

Scalp Threading for Hair Loss: Does PDO Add Benefit Beyond Scalp Wounding? | Expert Dermatologist Guide

Scalp threading for hair loss has emerged as a procedural option for androgenetic alopecia and female-pattern hair loss, usually involving absorbable polydioxanone (PDO) threads placed beneath the scalp.

As a UK-trained dermatologist and dermatopathologist, Dr. Sasi […]

Long-Term Effects of Botox treatment
Long-Term Effects of Botox: What It Can and Cannot Change | Expert Dermatologist Guide

The long-term effects of Botox are often discussed as though smoother expression lines and slower facial ageing are the same outcome. They are not.

Emerging Cosmetic Treatments: What the Evidence Actually Shows | Expert Dermatologist Guide

Emerging cosmetic treatments are frequently promoted as breakthroughs for hair loss, pigmentation, skin ageing and facial rejuvenation. Exosomes, polynucleotides, “salmon DNA,” regenerative injections, intravenous vitamin drips and thread lifts may sound scientifically advanced, but that does not automatically mean their benefits have been established in reliable clinical trials. Dr. Sasi Kiran Attili is a UK-trained […]

Anti-Grey Hair Serums: Can They Really Reverse Grey Hair? | Expert Dermatologist Guide

Anti-grey hair serums are promoted as treatments that can reactivate pigment cells, reduce oxidative stress and restore a person’s natural hair colour. The biological explanations can sound convincing, but the clinical evidence remains limited. Dr. Sasi Kiran Attili is a UK-trained dermatologist and board-certified dermatopathologist who evaluates hair disorders by separating plausible mechanisms from outcomes […]
