Retinol is one of the most proven ingredients for improving texture, signs of ageing, and cellular turnover, but its potency means it must be used thoughtfully. Conflicting advice often oversimplifies retinol pairing, yet effective routines rely on understanding ingredient interactions, timing, and skin barrier support. Whether you’re starting with INKEY’s Starter Retinol or using our Advanced Retinal that works up to 11 times faster, the right layering approach ensures maximum benefits while protecting skin health. This guide breaks down the science behind retinol compatibility into clear, practical advice so you can use retinoids with confidence—not caution.

Smart skinimalism is the 2026 skincare trend redefining results through simplicity. Backed by science, this approach prioritises skin barrier health and multi-functional ingredients over excessive layering. Discover why simplified routines can reduce irritation by up to 40% and how to build an effective, evidence-based 3-step routine for healthier, more resilient skin.

Your skin is constantly communicating beneath the surface—millions of microscopic messages coordinating repair, hydration, and regeneration every second. These messages are carried by exosomes: nano-sized cellular messengers that tell your skin exactly how to respond to damage, stress, and daily wear. Now, this breakthrough science is making its way into skincare. Exosomes don’t just sit on the surface—they help enhance your skin’s own communication systems, supporting collagen production, barrier repair, and visible radiance from within. Think of them as your skin’s internal text messages, delivering precise instructions where they’re needed most. Discover how exosome technology is redefining skin health and why it represents a new era of smarter, more efficient skincare.

In the world of regenerative skincare, two ingredients are leading the conversation: PDRN and retinol. Retinol has long been the gold standard for skin renewal, backed by decades of research and proven results. But PDRN represents a new generation of skin regeneration—working with the skin’s natural repair processes to boost glow, strengthen the barrier, and improve resilience with minimal irritation.

In this guide, we break down how PDRN and retinol work, their key benefits, potential side effects, and how to choose the right option for your skin goals. Whether you’re drawn to the instant radiance and barrier support of PDRN Serum, or the time-tested anti-ageing power of Starter Retinol and Advanced Retinal, this comparison will help you decide which approach—or combination—makes sense for your routine.

PDRN (Polydeoxyribonucleotide) is one of skincare’s most talked-about regenerative ingredients—but is it really worth the hype? This science-led guide explores how PDRN works, what the research says about collagen and barrier repair, and the safety and ethical questions around salmon-derived formulas. We also look at next-generation alternatives that deliver regenerative results without compromising on values.

Retinol vs bakuchiol is one of the biggest debates in anti-aging skincare right now, with experts split between proven performance and gentle, natural alternatives. This guide cuts through the noise with clear, science-backed insights into how each ingredient works and how they compare. The truth is, there’s no single winner—retinol delivers powerful, research-backed results, while bakuchiol offers a gentler option for sensitive skin. The key is choosing what best suits your skin, lifestyle, and tolerance.

Effective anti-aging doesn’t need a 12-step routine or luxury price tags—it needs the right science-backed ingredients used consistently. In this guide, you’ll learn what actually causes skin to age, which actives are proven to work, and how to build simple AM/PM routines for real results. No hype—just honest skincare that fits your life (and your budget).

Exosomes are redefining skincare by working at the cellular level to support collagen production, hydration, and skin renewal. Once used primarily in medical research, this advanced technology is now available in plant-based skincare formulations that help improve firmness, calm inflammation, strengthen the skin barrier, and deliver visible glow. This guide explores how exosomes work, their key skin benefits, how to use them effectively, and why plant-derived exosomes are shaping the future of skin rejuvenation.

If your skin feels rough, looks dull, or gets stuck in a cycle of congestion, glycolic acid could be the game-changing ingredient you’ve been missing.
