Hello into-skin
You sound very enthusiastic about products for skin and it is good that you are studying some of the basics at school.
Indeed, pH is very important to evaluate because too high or too low pH may cause much harm to skin, including serious injury or bleeding. If applied around eyes it may cause damage to eyes, including blindness in severe cases. If your product is not in a water base or if it contains very little water it may not always be possible to measure pH via conventional means and you should consult an expert on how to evaluate such a product. However, pH is not the only important thing to remember about skincare. There are many other issues such as concentration of certain ingredients, ingredients you should avoid, and preservation of the finished formulation so that it will not be contaminated by bacteria and fungi and cause health problems to the users.
Haloxyl is the same as palmitoyl tetrapeptide-3 but is already diluted in a mixture of inert materials which support solubilization of the active ingredient. The Haloxyl mixture includes glycerine, which you should not add to a finished product because it may destabilize the formulation; this probably means you should not add it to a Matrixol eye cream. There are many other ways, with less complex ingredients, to accomplish what the Haloxyl mixture claims to do in terms of improving the appearance of dark spots around the eyes. I don't believe in magic ingredients and you can make very good and effective products without the need to spend money on hype ingredients. They may be good but they are not extraordinary in any way other than price. Keep it simple while you learn. You are bound to make mistakes but try not to make expensive mistakes and definitely not dangerous mistakes.
Thank you for your question.
