"10% Niacinamide!" "20% Vitamin C!" Marketing loves big numbers, but do higher percentages actually mean better results?
The Percentage Myth
Higher concentrations aren't always better. In fact, they can sometimes be worse:
- Irritation risk: Higher percentages increase the likelihood of skin irritation
- Diminishing returns: Past a certain point, additional concentration offers no added benefit
- Formulation matters more: How an ingredient is delivered matters more than raw percentage
What Science Actually Shows
**Niacinamide**: Studies show optimal results at 2-5%. Going higher increases irritation without improving efficacy.
**Vitamin C**: Effective at 10-20%, but the form and pH matter more than percentage. An unstable 20% serum is worse than a stable 10% one.
**Retinol**: Often effective at very low percentages (0.025-0.1%). Higher percentages require careful introduction and can cause significant irritation.
**Hyaluronic Acid**: Typically effective at 1-2%. The molecular weight variety matters more than concentration.
The HER STORE 24 Approach
We formulate at optimal, not maximum, concentrations. Our goal is results without irritation. Every percentage in our formulas is chosen based on clinical research, not marketing appeal.
What to Look For
Instead of chasing high percentages, look for: - Stable formulations - Appropriate pH levels - Complementary ingredient combinations - Brands that can explain WHY they chose their concentrations
Remember: the best skincare is the one you'll use consistently without irritation. That rarely means the highest percentage available.
