Are You Aware of What You're Really Using in Your Skincare?
In 2026, among the most sought-after topics in skincare in Turkey, the ingredients of products are particularly of interest, including hyaluronic acid serum, what is retinol, and benefits of niacinamide.
However, the first step to choosing the right product is not to follow trends, but to be able to correctly read the ingredient list behind the product.
This ingredient list on the back of cosmetic products is technically called INCI (International Nomenclature of Cosmetic Ingredients). INCI is the system where ingredients are written with internationally standardized names and according to a specific order rule.
In this guide, we discuss how to read ingredients in skincare products in a simple yet scientific framework.
How is the Ingredient List Ordered?
The ingredients on the back of a product are listed in decreasing concentration.
This means that the substances at the beginning of the list are the highest proportion components of the formula.
For example, if you are buying a hyaluronic acid serum and Sodium Hyaluronate is listed among the first ingredients, the product may genuinely be designed for hydration. However, if it is at the end of the list, this ingredient may have been used in a low proportion.
Ingredients below 1% are generally listed at the end, and beyond this point, the order does not necessarily have to be by concentration.
It is crucial that some of the most commonly used ingredients in recent years are also in their most suitable form for our skin. Let's explain this with examples.
For example, retinol can be written in different forms in the ingredient list:
- Retinol
- Retinyl Palmitate
- Retinal
- Retinaldehyde
These forms are not equally potent. Especially for home and individual use, Retinyl Palmitate is a gentler retinoid derivative and is better tolerated by sensitive skin. Therefore, simply saying "it contains retinol" is not enough; the form in which it is present is important.
The very popular niacinamide is written as "Niacinamide" in the ingredient list and is generally used for:
- Reducing the appearance of spots
- Balancing sebum
- Evening out skin tone
However, for it to be effective, it needs to be formulated at a sufficient concentration. Clinical studies have generally found a range of 2–5% to be effective.
Also, one of the rising topics is skin barrier repair. A product may only provide moisture. However, to strengthen the barrier, both water-retaining and lipid-supporting ingredients must be present together.
In barrier-supporting products, the following groups should be sought in the ingredient list:
Humectants:
- Glycerin
- Hyaluronic Acid
Lipid supporters:
- Botanical oils
- Ceramides
Soothing and antioxidant ingredients:
- Panthenol
- Tocopherol
What to Pay Attention to When Reading Serum Ingredients?
When looking for an anti-aging cream recommendation or serum, the following questions should be asked:
- Where is the active ingredient in the list?
- Is the formula balanced?
- Are there ingredients in the same product that could neutralize each other?
- Is the pH balance appropriate?
For example, products containing acids include pH-regulating components. In products containing retinoids, antioxidant systems that ensure stability are important.
Reading ingredients is not just about looking at names; it's about understanding the formula's logic. Therefore, from ingredients of the right quality
