Avocado Oil vs Rosehip Oil – Which Is Better for Your Skin?

by ThankMeNow Editors on Sep 11, 2025
Avocado Oil vs Rosehip Oil — two nutrient-rich botanical allies with very different personalities. Avocado Oil, dense in oleic acid and Vitamin E, deeply nourishes, restores elasticity, and cushions dry or mature skin. Rosehip Oil, on the other hand, feels lighter and radiantly silky — rich in linoleic acid and natural Vitamin A esters that refine tone and enhance luminosity. Together, they represent balance: one comforts, the other brightens. Whether you crave barrier repair after exfoliation or a morning glow before makeup, understanding their fatty acid profiles helps you choose with confidence. In this dermatologist-style guide from ThankMeNow (TMN), learn when, why, and how to use each oil — with ingredient synergies, scientific insight, and emotional depth that make skincare a daily act of kindness 🌸

Vitamin C vs Ferulic Acid – Do You Need Both?

by ThankMeNow Editors on Sep 11, 2025
Vitamin C (Ascorbic Acid) is a gold-standard antioxidant that brightens, supports collagen, and shields skin from photoaging. Ferulic Acid is a plant-derived phenolic antioxidant that stabilises and enhances other antioxidants — especially Vitamin C and E — helping them resist oxidation, heat, and light. When paired, this duo forms a scientifically proven defense against environmental stress while visibly improving tone, firmness, and glow. Think of Vitamin C as the spark; Ferulic Acid is the guardian that keeps it shining. ✨

Combining peptides and retinol in your skincare routine can deliver exceptional anti-aging and skin-repairing benefits when layered correctly. A balanced approach is to use peptides in the morning (AM) for hydration and barrier support, and retinol at night (PM) to boost cell renewal while you sleep. This technique maximizes results and minimizes irritation (DermNet NZ).

by ThankMeNow Editors on Sep 11, 2025
Ever wondered why some people’s skin glows effortlessly with retinoids while others end up red and flaky? 🌙 The secret lies in choosing the right form of Vitamin A — Retinol or Tretinoin. Both are skincare superheroes that refine texture, soften wrinkles, and unclog pores — but their strength, speed, and gentleness differ.
