Are there any ingredients you're not a fan of?

We always talk beneficial aspects of cosmetics and ingredients used in beauty products, but every person has ingredients and products they don't like. Estheticians or cosmetologists aren't better. I think this discussion might help all of us find the reasons why some products or ingredients don't work for us Niacinamide Do you also think that niacinamide is in every product? I'm not a fan of niacinamide, although it has great properties for all ages and all skin conditions. It helps with acne, brightens the skin, and most importantly - it's a water-soluble vitamin. The problem I have is the amount of niacinamide in our skincare routines. Brands are trying to put the biggest amounts of niacinamide in products without thinking that we already have 2-5% of niacinamide in other products in the routine. The thing is that the majority of research is based on the lower concentration of niacinamide, we know how well it works for skin in 4-5% concentration. If your skin is red after a skincare routine, the problem might be in niacinamide - especially for sensitive skin, niacinamide concentrations above 2% might be problematic. It all depends on concentration and formulation. Zinc If you have acne-prone skin, then zinc is an ingredient you have to try. In some cases of acne or allergies zinc supplements might be needed (remember that before adding supplements to your daily routine, it's good to do a blood test and consult a doctor or specialist like a dietitian or nutritionist), but normally in diet, it's better to just eat food rich in zinc than use a supplement. Zinc doesn't only work from the inside, it can be also used as a spot treatment. Lots of companies are mixing zinc with niacinamide. Even if zinc is helpful, in some cases zinc can make your acne worse. If you have such problems, switch zinc treatments to calamine ones. Wheat Oil - Triticum Vulgare (Wheat) Germ Oil I enjoy using oils in skincare and haircare, but each oil won't fit every person the same. I'm not a fan of "Comedogenic rankings" because the comedogenity of ingredients was tested on rabbit's ears. Our skin is not as sensitive as rabbit ears. Why I don't like this ingredient is simple - wheat can be problematic for people with food allergies, celiac disease or Crohn's disease. It's also a very heavy oil and the only people I see this oil can work are people with super dry skin. A better choice is squalane - an ingredient that naturally occurs in our sebum. Glycolic Acid Glycolic Acid is a great ingredient, it's the best AHA available because it has a small molecule, which makes it more powerful. Not every skin is going to tolerate it. If you have sensitive skin then mandelic acid can work better for you. Another option is PHA instead of AHA. Sometimes milder products used for a longer amount of time is better than quick results on the product with higher concentration. Let me know which ingredients you don't like and why
