NAD+ is becoming one of the fastest-growing longevity ingredients in K-beauty—but shopping for an NAD+ product is already more complicated than finding the biggest number on the label. The products in this guide use very different formula strategies. Some contain direct NAD+. Others combine NAD+ with: And some brands disclose percentages, ppm, ppb, complexes, or … Read more
NAD+ skincare has moved quickly from longevity research language into K-beauty. In 2026, NAD+-related ingredients are appearing in serums, creams, and treatment-style products, including formulas that combine NAD-related positioning with ingredients such as PDRN. The biology behind NAD+ is real. The skincare conclusions are less simple. NAD+ is essential to cellular energy metabolism and is … Read more
Sensitive skin usually needs fewer variables, not more skincare steps. If your skin often stings, burns, becomes red, feels itchy, or reacts after you introduce new products, starting a complicated K-beauty routine can make it harder to figure out what your skin actually tolerates. A better starting point is simple: Gentle cleanse → moisturize → … Read more
A Korean skincare routine does not need 10 steps. For most people, the useful framework is much simpler: Cleanse → treat → moisturize → protect. Toners, essences, ampoules, serums, masks, and other K-beauty steps can be added when they serve a clear purpose—but they are not automatically required. The American Academy of Dermatology recommends a … Read more

PDRN skincare is becoming much easier to find in the U.S. Sephora now carries both traditional salmon-derived c-PDRN products and newer plant-based products marketed with proprietary PDRN-inspired or PDRN-branded ingredient systems. Those products should not automatically be treated as the same material or … Read more
Exosomes are becoming one of the most talked-about concepts in Korean skincare, regenerative aesthetics, and post-procedure beauty. You may see the term on serums, ampoules, “skin boosters,” spicule products, and treatments marketed for smoother texture, elasticity, hydration, or younger-looking skin. But there is an important problem: The word “exosome” on a skincare label does not … Read more
Spicules may sound like another futuristic K-beauty ingredient, but they are better understood as a skincare delivery technology. They are microscopic, needle-like structures used in some topical formulas to physically interact with the outer layers of the skin. You may have seen products containing them described as “liquid microneedling,” “micro-needle skincare,” or through names such … Read more
Anua PDRN vs Medicube PDRN is a much closer comparison than the packaging makes it look. Both are Korean PDRN serums positioned around hydration, glow and firmer-looking skin, but their supporting formulas are different enough that one may make more sense for your routine than the other. As of August 21, 2026, Anua’s U.S. site … Read more
PDRN vs retinol has become one of the more interesting skincare comparisons of 2026 — especially after a new clinical study tested them head-to-head.
