Quick answer
The ingredient list on the back of every product tells you more than the marketing on the front. Here is how to actually read it.

Shop all verified products →The front of a product is marketing. The back — the ingredient list — is the truth. It’s written in a standard format called INCI (International Nomenclature of Cosmetic Ingredients), and once you can read it, you can judge any product yourself. (See the glossary for term definitions.)
The 5 rules of reading INCI
- Order = concentration (mostly). Ingredients are listed high-to-low. The first 5 make up the bulk of the formula; anything after “fragrance/parfum” is usually present in tiny amounts.
- Find the actives. Look for the ingredient you bought it for — niacinamide, salicylic acid, vitamin C (ascorbic acid), sodium hyaluronate. If it’s near the bottom, there may be very little of it.
- Names aren’t scary. “Sodium hyaluronate” = hyaluronic acid; “Tocopherol” = vitamin E; “Snail secretion filtrate” = snail mucin; “Centella asiatica extract” = cica.
- Watch your triggers. Fragrance/parfum, high alcohol (“alcohol denat.”) or essential oils can irritate sensitive or barrier-damaged skin. (See sensitive-skin routine.)
- Check the symbols. The little open-jar “12M/6M” mark = months usable after opening; find the batch code/expiry too (how to verify it).
Why this also protects you from fakes
A genuine product has a clean, correctly-spelled, properly-formatted INCI list. Counterfeits often have misspellings, missing lists, or ingredients that don’t match the brand’s real formula — a quick authenticity tell. (See how to identify fakes.)

Frequently asked questions
How do I read a skincare ingredient (INCI) list?
Ingredients are listed high-to-low by concentration, so the first few make up most of the formula. Find the active you bought it for, learn that scientific names (e.g. sodium hyaluronate = hyaluronic acid) aren’t scary, watch for your irritant triggers, and check the open-jar PAO symbol and batch code.
Does the ingredient order really mean concentration?
Mostly yes — ingredients are listed from highest to lowest amount. Anything listed after fragrance/parfum is usually present in very small amounts.
Can the ingredient list help me spot a fake?
Yes. Genuine products have clean, correctly-spelled, properly-formatted INCI lists. Misspellings, missing lists, or ingredients that don’t match the brand’s real formula are quick authenticity red flags.
Where should I buy skincare if I want the ingredient list to actually match what's inside the bottle?
Buy from a seller who can show the importer's invoice and batch number, since even an accurate-looking ingredient list on a counterfeit box doesn't guarantee what's really inside. Checking the batch code against the product itself adds another layer of confidence.
Does Bangladesh's heat affect how fast ingredients on the label break down?
Yes, unstable actives like vitamin C or retinol listed near the top of the ingredient list degrade faster in heat and direct sunlight, especially in clear or jar packaging. Opaque, airtight packaging and cool storage help the formula stay effective longer.
