5 scientific beauty tips from the author of Lab Muffin

The Australian chemistry teacher Michelle Wong is well-known as the author of the science blog about cosmetics, Lab Muffin, and she also has a very useful YouTube channel - Lab Muffin Beauty Science.

Michelle Wong likes to talk about the effects of cosmetics with the help of her education and work experience. In the Instagram, she has adopted a visual format of "cards" where Michelle dispels common myths: such as that all antioxidants are incredibly useful, that a sunscreen with SPF 50 is hardly better than SFP 30 and that the pores can be opened and closed.

Our favorite beauty tips from Michelle:

How to read cosmetic ingredients?

The rule "don't apply ingredients which are hard to read" doesn't work. Those who believe in this, say that the easy-to-pronounce natural ingredients are more useful for the skin than synthetic ones. In fact, even in pineapple, there are substances with names from dozens of letters and numbers: for example, 2,5-dimethyl-4-hydroxy-3 (2H) -furanone (in a simple way - furanone). And the naturalness of the composition itself means nothing in terms of efficiency - poisons are natural too.

Do cosmetics with antioxidants work?

Free radicals are molecules in which electrons are "taken away" and which "compensate" them from other molecules. They can cause both useful and not very useful reactions. For example, they can help to treat acne but age the skin due to invisible damage to DNA, skin fats and proteins. Harm from the free radicals can be reduced, even when free radicals have already started a chain of damage, - with the help of antioxidants, which have an "extra" electron. The effectiveness of some antioxidants in cosmetics has been proven: for example, superoxide dismutase, catalase, vitamins C and E, ubiquinone, ferulic acid. The rest Michelle lists in her video.

Can you combine different sunscreens? 

On the one hand, layering UV filters (for example, sunscreen and makeup product with sunscreen properties) can be useful. On the other hand, it's very difficult to predict how the sun filters in the first medium will interact with the filters in the second. For example, avobenzone is an effective but very sensitive filter, so it's better not to mix it with octinoxate, titanium dioxide and zinc oxide. The general rule is this: layer the same sunscreen, or sunscreen with the same filters. 

 

How to help dehydrated skin? 

Normal, oily, combination and dry skin can be dehydrated. The main task in this case is to prevent the loss of moisture. Water-retaining components such as: glycerin, sorbitol, glycols, hyaluronic acid, urea, amino acids, AHA-acids will help. They should be applied to damp skin so they can keep more water. For the same reason, minerals are useful (they are generally called a natural moisturizing factor). There're a lot of minerals in thermal sprays. 

How to get rid of pigmentation? 

To avoid dark spots after pimples, sunburn and wounds use sunscreen with high UVA protection: with filters like avobenzone, zinc oxide, and better - with stable tinosorgom M and S, mexoril SX and XL, juvenle A plus. Vitamin C will help to lighten the already excisting pigmentation, and lactic and almond acids will also exfoliate the skin, prevent the emergence of new inflammations. But don't overuse the acids, otherwise, you can get a chemical burn.
