01 / What people use it for
A serum is a skincare product many people add between cleansing and moisturizer. Most are thin liquids that sit lightly on the skin. People reach for one for how it feels: a fresh, hydrated feel, a routine step of their own, a small ritual morning or night.
A cosmetic is not a treatment. This guide does not promise results, and no label can promise them for you. It teaches you what to look at, so you choose with open eyes.
Skincare only. For a skin condition or a worry about your skin, ask a dermatologist.
02 / How to read a label
- Find the ingredient list, usually on the box or the back of the bottle. Read it top to bottom.
- Ingredients are commonly listed from most to least by amount, so the first few tell you what the product is mostly made of.
- Look for anything you already know does not suit you, such as a fragrance you avoid or an ingredient you reacted to before.
- Check the size and the price per ounce, then compare with a shelf neighbor of the same size.
- Try one new product at a time, on a small patch first, so you can tell what is what.

03 / Who to ask
A pharmacist or a dermatologist can tell you about a skin condition and about what suits your skin. A shop assistant can tell you what is on the shelf. Use the guide for the vocabulary, and the professional for the person in front of them.
