Does a moisturizer enhance your skin or worsen your skin?

I have done a small experiment based on an article that I have read a few months ago .

It teaches us how to differentiate the ingredients used in the skincare products that are common in our facial routine.

One of it is on how to differentiate whether the moisturizer  we use actually helping us to hydrate our skin or just contain petrolatum / mineral oil that will clog our pores.

The method of testing is firstly , get a paper and dab a small amount of the moisturizer on the paper and for it to dry. Next, check and see whether the part where the moisturizer is dabbed is wrinkly or slightly translucent.

If it is slightly translucent , that means it contain petrolatum/ mineral oil. 

On the other hand if it just turn wrinkly , that means the product helps to hydrate the skin without the use of petrolatum

I did this experiment based on a few moisturisers that I have been using . These are :

 

BIOTHERM AQUASOURCE (normal to combination skin )

FRESHEL (BY KANEBO ) WHITENING UV GEL

ZA TOTAL HUDRATION AMINO REFRESHING GEL

NARUKO ( by Niu Er)Magnolia Brightening and Firming Night Gelly EX 

NARUKO白玉兰雪耳钻采紧致晚安冻膜

SKINCOLOGY (by Niu Er)ADVANCED HYDRATING CREME EX2 玻尿酸全效循環保濕水凝霜

And it turns out that  

1.biotherm contain quite a high amount  of petrolatum

2.freshel contains the most ( I am not sure whether it is due to the UV protection function of it )

3.Za has a minimal amount

4.Naruko negative traces of petrolatum 

5.skincology  negative
