How to read a skincare ingredient list: a plain-language guide
Updated · 4 min read
Skincare labels can read like a chemistry exam. Most of what you will see falls into a few simple groups. Here is how to make sense of them — without the hype.
Hydrators: the water-lovers
Hyaluronic acid, glycerin and panthenol draw in and hold water, which is why hydrating serums feel light and leave skin feeling plump and soft. They show up in almost every serum, whatever else is in it.
Softeners: the comfort layer
Squalane, shea butter and plant oils smooth the surface of skin and leave it feeling supple. Ceramides are a familiar part of richer creams that help skin hold on to moisture and feel comfortable.
Lighter formulas lean on fewer softeners; night creams tend to use more.
Finishers: how skin looks
Niacinamide and plant extracts like licorice root often appear in serums aimed at skin that looks more even and radiant. Consistency matters more than any single ingredient: a routine you enjoy and use every day will do more for how your skin looks than an occasional splurge.
Be wary of any cosmetic that promises medical-style results. Cosmetic skincare is about how skin looks and feels.
Putting it together
Whatever the ingredient list, the routine is the same: serum first on clean skin, cream on top, sunscreen in the morning.
- Use products once or twice a day, morning and/or night.
- Pair a very light serum with a moisturizer.
- Introduce one new product at a time.
Checking whether a product suits you
Trying something new? Patch test it first, and stop using any product that causes irritation. Our usage and safety page walks through a simple patch test.
Questions
Why is water usually the first ingredient?
Ingredients are listed from the highest amount to the lowest, and most serums and creams are water-based, so water tends to lead the list.
Can I use products with different ingredients together?
Hydrating serums and moisturizers usually layer easily. Add one new product at a time so you can tell how each feels.
How long before I notice a difference?
Skin can feel softer and more hydrated right after applying. How skin looks over time depends mostly on using your routine consistently.
For external cosmetic use. Patch test new products and stop use if irritation occurs. See ingredients & safety.
