Why New Dermatological Evidence Favours Low-Dose Tretinoin

Scientific illustration of translucent skin cells with glowing molecular pathways, symbolising tretinoin's effects on cellular renewal and skin regeneration.

In modern skincare culture, an enduring assumption persists: higher concentration inevitably yields superior clinical results. When applied to topical tretinoin (all-trans retinoic acid), this “more is better” mindset frequently prompts consumers and clinicians to accelerate dosage strength from 0.025% to…

Melatonin and Heart Failure: What the New Research Really Shows

Scientific visualisation of cardiac tissue and glowing biochemical pathways representing melatonin and cardiovascular health.

Sensational headlines claiming that everyday sleep supplements increase the risk of heart failure have triggered widespread alarm among health-conscious consumers. However, a rigorous examination of the underlying epidemiological data reveals a classic distinction between correlation, confounding variables, and genuine pharmacological…

Melatonin’s Influence on Blood Cholesterol Levels

Scientific visualisation of the human brain, neurons and biochemical signalling representing melatonin and metabolic regulation.

Melatonin is widely recognised for its role in regulating sleep and circadian rhythm. However, growing research suggests its physiological influence extends beyond sleep – including potential effects on lipid metabolism, oxidative stress, and cardiometabolic health. Recent clinical investigations have examined…

DHEA: New Evidence in Fertility and Hormone Health

Scientific visualisation of interconnected neurons and biochemical signals representing DHEA and neuroendocrine activity.

Dehydroepiandrosterone (DHEA) has long been recognised as a key precursor hormone, supporting the production of both androgens and oestrogens as we age. While many of DHEA’s established benefits, including energy, mood, and age-related hormone decline, are already well documented, recent…

Melatonin and DNA Repair: New Scientific Insights

Glowing DNA double helix undergoing cellular repair, representing melatonin’s role in nighttime DNA protection.

Melatonin is widely recognised for its role in regulating sleep, but emerging human research suggests its biological influence may extend further, potentially supporting the body’s natural ability to repair oxidative DNA damage during sleep. Recent findings from a randomised, placebo-controlled…
