When I traveled to South Korea last year, I expected wonderful food, deep history, and a culture that takes skin care seriously. What I didn’t expect was how overwhelmed I would feel standing in front of shelves packed with products promising transformation of the skin through ingredients I had barely heard of—especially snail mucin.

The confidence was striking. The packaging was elegant. Testimonials were everywhere. Many people genuinely swear by these products. Still, a quieter question surfaced: How do we know what really works? Modern skin care moves quickly. Once a novel ingredient gains attention—especially one that sounds exotic or cutting-edge—companies rush to include it. Soon, the market fills with nearly identical products, each promising visible results. That doesn’t mean these products are useless. But it does mean that newness itself often becomes the selling point. And this way of thinking doesn’t stop at skin care.

Snail mucin has been studied primarily in small or short-term settings. Most of the available data comes from open-label studies, laboratory research, or subjective outcomes such as hydration and smoothness. At best, snail mucin functions as a hydrating, barrier-supportive ingredient. It can soften the surface. It can make the skin feel better. What it has not been shown to do is fundamentally change the deeper structure of the skin over time.

Is there anything that does work? Retinoic acid is not trendy. It doesn’t rely on testimonials or viral enthusiasm. It rests on decades of careful, controlled science. Well-designed studies have consistently demonstrated its ability to: increase dermal collagen, normalize epidermal turnover, improve acne and photoaging, and produce reproducible, long-term results.

Earlier in my career, I had the privilege of doing research with one of the co-discoverers of retinoic acid as a treatment for skin disease. What struck me then—and still does today—was how quietly the work spoke. There was no hype. No rush. Just careful observation, patience, and truth revealed over time. And often, that truth wasn’t comfortable at first. Retinoic acid frequently causes redness, peeling, and irritation before improvement appears. But those early effects are signs that something deeper is actually happening.

Here is where the analogy becomes unavoidable. Snail mucin can soften the surface. Retinoic acid exposes and treats what lies beneath. In the same way, until we see our sin clearly, grace will always seem optional. Until we recognize our need, salvation will always feel like an accessory.

The gospel does not begin with innovation. It begins with confession. Just as retinoic acid reveals damage before it heals, God’s Word exposes what we would rather ignore—not to shame us, but to restore us.

For the word of God is living and active, sharper than any two- edged sword, piercing to the division of soul and of spirit, of joints and of marrow, and discerning the thoughts and intentions of the heart.

(Hebrews 4:12)

Conviction can feel uncomfortable. It can sting. It can peel away illusions we’ve grown accustomed to. But without that exposure, no real transformation is possible. The modern church, like modern skin care, can drift toward surface solutions—exceptional music, carefully produced services, online engagement metrics, and constant accessibility—while quietly assuming these things can accomplish what only God’s Word can do. These things may attract us, but they cannot diagnose our condition or cure our disease. What we truly need is God’s Word to show us our sinful state, so that we can confess and repent—and receive what we cannot produce ourselves.

If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.

(1 John 1:9)

Grace is not cosmetic. Grace is transformational. And it comes only through Jesus Christ as Lord and Savior.

There is nothing wrong with curiosity. There is nothing sinful about trying something new. But neither novelty nor innovation—whether in skin care or in church—can replace what has always been necessary. Truth must come before transformation. Conviction must come before comfort. And grace must be received, not applied.

Love and trust the Lord; seek His will in your life.
