With thousands of skincare ingredients on the market, it can be overwhelming to know what actually makes a difference. Here are five ingredients with robust scientific evidence behind them.
1. Niacinamide (Vitamin B3)
One of the most versatile ingredients in skincare. At 2-5% concentration, niacinamide reduces redness, minimizes pores, and strengthens the skin barrier.
## 2. Ceramides
These lipid molecules make up 50% of your skin barrier. Topical ceramides help repair and maintain this crucial protective layer.
## 3. Peptides
Short chains of amino acids that signal your skin to produce more collagen. Effective for anti-aging without the irritation of retinoids.
## 4. Squalane
A plant-derived oil that mimics your skin's natural sebum. Lightweight, non-comedogenic, and suitable for all skin types.
## 5. Glycerin
A humectant that draws moisture from the environment into your skin. Found in nearly every effective moisturizer for good reason.
