A SKIN1004 ampoule might seem easy to choose at first: look for Centella Asiatica, pick the size you want and add it to your routine. But the formulas can be quite different. A hydrating serum for sensitive skin contains different ingredients from an azelaic acid ampoule or a retinol ampoule.
The product name and marketing claims don’t tell the whole story. Pay close attention to the ingredients list, the concentration of active ingredients and the directions for use. This can help you avoid buying a formula that’s too intensive, or choosing a small bottle when you use several layers every day.
Madagascar Centella and Centella Asiatica are often mentioned as soothing ingredients. However, the exact formula can vary considerably. One ampoule may mainly contain Centella extract, while another may also contain niacinamide, tranexamic acid, azelaic acid, retinol or peptides.
So look beyond the front of the packaging. Check that the formula suits your goal: hydration, a more even-looking complexion, pore care or a lighter routine for sensitive skin.
An azelaic acid ampoule with 10% azelaic acid, or a product containing retinol and retinal, needs more care than a simple Centella serum. According to SKIN1004’s product information, the azelaic acid version may cause mild tingling or warmth at first. If irritation persists, reduce how often you use it or stop using it.
The product information for the retinol version notes that redness or a tingling sensation may occur. So don’t automatically start using products like these every day from the outset.
A 100 ml bottle contains more product than a 9 or 30 ml ampoule, but that doesn’t mean the formula is stronger. A smaller size can actually be useful when trying an active formula for the first time. A larger size is a better choice once you know the texture and ingredients work well with your routine.
For a simple, lightweight routine, look for Centella Asiatica, glycerine, panthenol and hyaluronic acid. These ingredients feature in several hydrating and soothing formulas.
If you want to address a dull-looking complexion, compare options containing niacinamide, tranexamic acid, a vitamin C derivative or madecassoside. According to its ingredients list, the Tone Brightening Capsule Ampoule contains niacinamide, tranexamic acid, madecassoside and 3-O-ethyl ascorbic acid, among other ingredients.
For pore care and acne-prone skin, the product’s positioning and instructions are more important than a bold claim on the packaging. According to the product information, the Tea-Trica Relief Ampoule contains Centella Asiatica, tea tree water and ingredients that give it a light, non-sticky texture. Always check that your skin can tolerate tea tree and other botanical ingredients.
A watery ampoule usually absorbs quickly and can be layered easily under a moisturiser. This is practical for combination or oily skin, or if you use several steps in your routine.
A richer formula containing ingredients such as squalane, olive oil-like emulsifiers or several humectants may feel more comfortable on dry skin. Don’t just look for words such as “light” or “intensive” in the product name; check the first ingredients on the INCI list too.

It depends on the version. A simple Centella ampoule contains fewer different active ingredients than an azelaic acid ampoule or a retinol ampoule. Check the full ingredients list, do a patch test and introduce it gradually. No cosmetic product is automatically suitable for every type of sensitive skin.
After cleansing, and applying toner if you use one, apply a few drops to your face. Gently pat the serum into your skin, then finish with a moisturiser. Use active formulas according to their specific instructions. You may need to use sunscreen during the day, as noted in the product information.
It depends on the size and how many drops you use each time. A 9 ml bottle is best suited to a short introduction or targeted use. A 55, 95 or 100 ml size is a better choice for daily use over a longer period. Check the packaging for the expiry date and any period-after-opening guidance.
