Best praise vs top criticism for iUNIK Beta-Glucan Power Moisture Serum
“I stumbled upon Iunik's Beta Glucan Sunscreen while ordering other skincare. I assumed it would have niacinamide in it, but decided to check just in case as I love and use their Beta Glucan Serum. Lo and behold, no niacinamide! I ordered it and it's my new HG sunscreen. When I was first getting into Korean skincare, niacinamide-free sunscreen options were soooo limited (there were like two I swear), so I'm choosing to take this as a sign that we are past peak niacinamide, and it will slowly get better from here.”
“And I double checked to make sure this was a good routine for you Yes — this routine gives her **ample hydration without clogging pores or triggering breakouts**, especially for **dry/combo skin in Arizona’s hot, dry climate**. Here’s how and why: # ✅ Hydration Layering (Without Heaviness) * **Toner (Anua Heartleaf 77 + Isntree Hyaluronic Toner)** Light and watery formulas layer beautifully. The Anua toner soothes inflammation, while Isntree deeply hydrates with multiple molecular weights of hyaluronic acid — perfect for desert dryness. * **Serum (Torriden DIVE-IN + iUNIK Beta Glucan / BOJ Glow Serum)** Both serums are **non-comedogenic and barrier-repair focused**. Torriden uses low molecular HA for deep hydration, while iUNIK’s beta-glucan holds 20% more moisture than HA and calms inflammation. BOJ Glow adds niacinamide and propolis, which help with moisture regulation and skin texture. * **Moisturizer (Illiyoon Ato + Etude Soon Jung)** These are **cream-based but breathable**, fortified with **ceramides and panthenol**. They hydrate, soothe, and reinforce the barrier **without trapping heat or sebum**—crucial in hot, dry climates. # ✅ Breakout Prevention * **Cleansers** are all **low pH, non-stripping**, and oil cleanser is emulsifying (won’t leave a film). * **No heavy occlusives or fatty alcohols** — the moisturizers and sunscreens avoid pore-clogging ingredients. * **Exfoliation (beplain gel)** is enzyme-based — **gentle enough** to prevent clogged pores without irritating dry zones. * **Retinol (SCINIC retinal)** is encapsulated and buffered with a full barrier routine to **minimize purge risk**. # ⚠️ Watch-Out Tips * Introduce **retinal only 2x/week at night** for the first month, then increase to 3x/week if no irritation. * If skin feels tight midday, she can layer another pump of **Torriden serum** under moisturizer or add a midday mist (e.g., d'Alba or Pyunkang Yul mist). **Conclusion:** ✅ **Balanced hydration** with anti-inflammatory ingredients ✅ **Barrier protection** without greasy occlusives ✅ **Non-comedogenic** and sensitive-skin friendly This routine is **safe, reparative, and breakout-minimizing** — ideal for her environment and skin type.”
