Skin Specialists: Find and review dermatologists in Malaysia and Singapore

Abstract Psoriasis is a chronic autoimmune condition affecting approximately 7.5 million individuals in the United States, with significant economic, physical, and psychological burdens. This case series reports on 13 patients who experienced notable improvements in psoriasis symptoms following treatment with ivermectin and/or fenbendazole, antiparasitic agents repurposed for this indication. Cases were derived from self-reported testimonials shared on social media platforms. Treatment durations ranged from 3 days to 3 months, with dosages varying between 6 mg ivermectin twice daily and combinations with fenbendazole. Rapid resolution of skin lesions was observed in most cases, with some achieving near-complete clearance. While these anecdotal reports suggest potential therapeutic efficacy, controlled clinical trials are warranted to validate these findings and elucidate underlying mechanisms. Introduction Psoriasis is a chronic inflammatory disorder characterized by hyperproliferation...

Best Vitamin D3 + K2 Supplements in 2026: Doctor-Reviewed Picks for Bone, Heart & Immune Health

By Dr Frank Yap, MD - January 05, 2026

Vitamin D3 and Vitamin K2 are two of the most commonly deficient—and misunderstood—nutrients today. While Vitamin D improves calcium absorption, Vitamin K2 determines where that calcium actually goes . That’s why taking Vitamin D without K2 may be incomplete—and in some cases counterproductive. After reviewing ingredient quality, dosing accuracy, brand transparency, and real-world user feedback, the following are the best Vitamin D3 + K2 supplements available in 2026 . Most people in the United States consume less than recommended amounts of vitamin D . An analysis of data from the 2017–2018 National Health and Nutrition Examination Survey (NHANES) found that average daily vitamin D intakes from foods and beverages were 4.3 mcg in men, 3.8 mcg in women, and 5 mcg (200 IU) in children aged 2–19 years ( NHANES 2017 - 2018 ). Why Trust This Guide? This review prioritizes supplements that meet four non-negotiable criteria : Uses Vitamin D3 (cholecalciferol) — not D2 Includes Vitam...

7 Best Cetylpyridinium Chloride Mouthwash Brands 2025

By Dr Frank Yap, MD - June 13, 2025

A meta-analysis of 3 studies (C19early 2025) concluded that CPC (CetylPyridinium Chloride) may significantly lower risk with viral clearance . One study shows significant benefit. Meta analysis using the most serious outcome reported shows 83% [6‑97%] lower risk . Results are consistent with early treatment being more effective than late treatment. A study, published in Nature ( Takeda 2022 ) concluded that CPC (CetylPyridinium Chloride) may inhibit SARS-CoV-2 infection even at lower concentrations. Another team of international scientists has also demonstrated the usefulness of cetylpyridinium chloride-containing mouthwashes in inhibiting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and reducing the risk of viral transmission. The study is published in the Journal of Medical Microbiology (2022). A scientific review, published in the Journal of Formosan Medical Association (2022) also concluded that mouthwash containing CPC shows potential fo...

17 Best Natural Ozempic Alternatives 2026 (Resource Guide)

By Dr Frank Yap, MD - January 10, 2026

Some of the best natural alternatives to Ozempic include berberine, a supplement that has shown potential in managing blood sugar and promoting weight loss, often referred to as “nature’s Ozempic” in wellness communities. High-fiber foods also play a crucial role by helping to control appetite and improve metabolic health. Other natural options include psyllium husk, which provides soluble fiber supporting satiety and digestive health, and curcumin, known for its anti-inflammatory properties, which may aid metabolic balance. Additionally, green tea extract, magnesium, protein-rich foods, and lifestyle factors like adequate sleep and stress reduction contribute to weight management. However, none of these natural alternatives are as potent or fast-acting as Ozempic itself, and their effects can vary widely among individuals. It is important to consult a healthcare provider before starting any supplement regimen, especially for managing blood sugar or weight loss. The 2023 rep...

Retatrutide vs Tirzepatide vs Semaglutide (Ozempic): GLP-1 Wars — Updated Review (2026)

By Dr Frank Yap, MD - January 07, 2026

The landscape of obesity treatment has evolved dramatically with the introduction of advanced medical therapeutics like retatrutide (RETA, LY3437943), tirzepatide (Mounjaro), and semaglutide (Ozempic). Glucagon-like peptide-1 receptor agonists and co-agonists, originally developed to manage type 2 diabetes, have shown remarkable efficacy in promoting weight loss, making them game-changers for obesity management. However, each drug has unique mechanisms, benefits, and potential applications, including emerging roles in cancer prevention. This article compares their mechanisms, clinical efficacy, broader health benefits, safety profiles, regulatory status, and practical considerations to help patients, clinicians, and informed readers understand how they stack up in 2026. Update: Are GLP-1s the first longevity drugs ?

Berberine and Natural GLP-1 Mimetics as Drug Alternatives (2026)

By Dr Frank Yap, MD - January 10, 2026

Introduction Prescription GLP-1 agonists like Ozempic and Mounjaro have revolutionized weight management and type 2 diabetes care. However, not everyone has access to these medications, and some prefer natural alternatives. Emerging research highlights berberine and certain natural GLP-1 mimetics as potential adjuncts or alternatives. These compounds may support blood sugar control, improve insulin sensitivity, and modestly aid natural weight loss — all through mechanisms similar to GLP-1 drugs. What Is Berberine? Berberine is a plant-based alkaloid found in barberry, goldenseal, Oregon grape, and other herbs . Mechanisms of Action: Activates AMPK , the body’s “metabolic master switch,” improving glucose uptake. Enhances insulin sensitivity . May increase GLP-1 secretion , helping regulate appetite and blood sugar. Clinical Evidence: Studies suggest berberine can reduce fasting blood sugar by 20–30 mg/dL . Modest weight loss of 5–7% over 12 weeks has been observed. Well-tolerated, w...

By Dr Frank Yap, MD - January 24, 2024

Do nasal sprays actually work against COVID-19? Can I use nasal spray if I have COVID-19? The COVID-19 pandemic has been roaring on for 3 years. During this time, the FDA has authorized many treatments that help combat COVID-19. COVID-19 vaccines have also been recommended by the CDC ever since the first ones were authorized in December 2020.

Aesthetic & Metabolic Science: How GLP-1, Weight Loss, and Biology Shape Aging

By Dr Frank Yap, MD - January 13, 2026

Understanding Beauty Through Biology, Not Trends Modern aesthetics no longer begins with injectables, devices, or skincare. It begins with metabolism, hormones, inflammation, and tissue biology . At AestheticsAdvisor , we approach aesthetics as a biological system, not a cosmetic one. Weight loss drugs, insulin resistance, chronic inflammation, and muscle loss now shape facial aging as much as wrinkles and sun exposure. Aesthetics Is Metabolism Made Visible The face and body are not isolated from internal health. Aesthetic aging reflects underlying biological processes. Insulin resistance Chronic low-grade inflammation Hormonal decline Mitochondrial dysfunction Loss of lean muscle mass Collagen degradation Medical weight loss—especially pharmacologically induced weight loss—accelerates or exposes these processes. GLP-1 agonists did not create aesthetic aging problems. They revealed them. GLP-1 Agonists: What They Actually Do Biologically GLP-1 recepto...

9 Best Anti Aging Skincare Hong Kong 2025

By Dr Frank Yap, MD - January 28, 2025

It’s natural to have complex feelings about noticing signs of aging. You can embrace the beauty and privilege that it is to age, while also not love all of the physical changes that come along with it. If you’d like to soften these signs but don’t want to go the injectables route, there are non-invasive products that can help. In the world of beauty products, there's perhaps no category more saturated than the anti-aging market. What to Look for in an Anti-Aging Product a. Vitamin C An antioxidant powerhouse, vitamin C is directly involved with collagen production in the body. Vitamin C is beneficial in anti-aging products for several reasons: It protects skin from environmental stressors, promotes cell turnover, and can fade dark spots which contribute to the appearance of aging skin. Products containing vitamin C can irritate sensitive skin, so be sure to start out using a low concentration if your skin is reactive. b. Retinoids Retinoids are a category of ingredients, and retin...
