Another Amazing Product from SKIN1004
I own at least 4 products from SKIN1004, because they really are a great skin care brand to invest in with. For reference, I have dry sensitive skin, I am prone to dark spots, some acne, dry patches and bigger pores. I have always had bad experiences with toner's so I was really hoping this would work for me. And it did more than that! I do believe my acne has gone down since using this, and to really test it out I finished the bottle after 5 and half months of daily morning and nighttime use. My skin feels smoother and bit brighter, more than anything it really keeps your skin clean without drying it out. It doesn't have a particular smell, the consistency is like water, and when you apply it is a bit tacky but no worries once it dries down completely, that goes away. This toner could be used by all skin types in my opinion. I will be trying their brightening toner soon, which I am even more excited about! Would repurchase.

Excellent product for sensitive skin
If you have sensitive skin, this product is essential for your skincare routine. It is excellent; I experience frequent acne breakouts, and it helps soothe my skin.

A Skin Saver
I've been using the Centella toner for a week now, and it's quickly become a staple in my skincare routine. Infused with Centella Asiatica extract, this toner is perfect for calming irritated or sensitive skin. The texture is light and watery absorbs quickly without any sticky residue making it ideal for layering or using as a refreshing mist throughout the day.
It is very soothing reduces redness and inflammation, especially after exfoliating or sun exposure. It is very hydrating and gives a subtle moisture boost without clogging pores.
It has no alcohol or fragrance, so it's great for sensitive or acne-prone skin.
I use it after cleansing and before serum, and I’ve noticed my skin feels more balanced and less prone to breakouts or irritation. It pairs well with other products and hasn’t caused any pilling or sensitivity.
If your skin leans sensitive, inflamed, or needs a calming reset, this Centella toner is worth trying. Affordable, gentle, and effective. I definitely recommend this product
