Chasing Higher Percentages in Skincare: Why More Isn’t Always Better

In recent years, skincare has turned into a numbers game. Labels proudly display 20% vitamin C, 10% niacinamide, or 2% retinol as if the bigger the number, the better the results.
It’s an easy marketing hook but it’s also a trend that can leave skin stressed, irritated, and less healthy over time.

Let’s break it down into The Hype, The Reality, and The Harm.

The Hype

Brands and influencers often present higher percentages of active ingredients as the fast track to visible results.
The idea is simple:

🚩   If 5% niacinamide makes a difference, 10% must work twice as well.

🚩   If 0.5% retinol is effective, 1% must be a game-changer.

🚩   If 10% vitamin C brightens, 20% will really get the glow.

Percentage marketing plays into our “more must be better” instincts, making it feel like you’re getting more potency, more value, and more results in every drop.

The Reality

In skincare science, more doesn’t always equal better. In fact, every ingredient has an optimal concentration range, a sweet spot where it’s effective without overwhelming the skin.

✅   Niacinamide: Most studies show great results at just 2–5%. Going higher doesn’t necessarily increase benefits but can increase flushing or redness in some people.

✅   Vitamin C (ascorbic acid): Usually most effective at 10–15%, especially when pH and stability are optimized. Above that, you may see more irritation but not proportionally better results.

✅   Retinol: A concentration of 0.1–0.5% can significantly improve fine lines and texture over time. Jumping straight to 1% without building tolerance often leads to unnecessary irritation.

Formulation quality such as pH, delivery system, ingredient stability, and supporting ingredients often matters more than the number printed on the label.

The Harm

Chasing high percentages can cause more trouble than it’s worth:

1.     Barrier Damage - Strong actives in high concentrations can strip away your skin’s protective barrier, leading to dryness, redness, and sensitivity.

2.     Increased Irritation - Overuse of high-strength products often triggers stinging, peeling, and inflammation which can take weeks to calm down.

3.     Breakouts & Sensitization - A compromised barrier can make skin more reactive, even to products that used to work fine.

4.     Wasted Product & Money - If your skin can’t tolerate the formula, you’ll use it less frequently (or stop altogether), meaning that “extra strength” product ends up gathering dust.

5.     Unstable Formulas - Pushing an ingredient past its stability limits can cause it to oxidize faster, making the product less effective before you finish it.

A Better Approach

Instead of chasing the highest number on the shelf:

·       Start low, go slow. Let your skin build tolerance before moving up in strength.

·       Look for balanced formulas. Well-paired supporting ingredients can make a moderate concentration work harder.

·       Focus on consistency over intensity. Results come from regular use, not occasional “skin boot camps.”

Healthy skin is a marathon, not a sprint. A product you can use comfortably every day will always beat one that’s too strong to use regularly.

Bottom Line:

The race for higher percentages is a marketing trend, not a skin health strategy. The most effective skincare isn’t about maxing out numbers, it’s about finding what works for your skin, at a strength your skin can love for the long haul.
