Most people using retinol are wrecking their skin barrier and have no idea 😬 Retinol is a demolition crew. It breaks down old skin so new skin can come in. That part works — the problem is the middle. Your barrier takes the hit, and you can end up losing more collagen than you build 📉 That’s the flaking. The stinging. The tight, crepey feeling that makes you think you need something stronger. You don’t. You need TECA 🧴 TECA is centella, but the concentrated pharmaceutical-grade version. It rebuilds the barrier and calms the pathways behind redness and puffiness. I use Centellian24 Time Reverse Zero 💧 🔹 Full 3% TECA 🔹 Retinol, buffered so your barrier isn’t taking the hit alone 🔹 Niacinamide + caffeine to even tone and tighten It has retinol, so wear your SPF ☀️ Comment SKIN and I’ll send you the link 👇 #philsmypharmacist #healtheducation #koreanskincare #pharmacyhacks #antiaging
