Skincare Ingredients: The Good, The Bad, and How to Know Which is Which

Skincare Ingredients: The Good, The Bad, and How to Know Which is Which

Posted By Vien

Skincare ingredients are the backbone of what makes products work. They're essential for figuring out which products will perform best for your skin type and skin issues. 

But, not all ingredients are made equal, just like with most things in life. When taken in specific combinations, some have been shown to irritate the skin or even result in malignant growth. Others are well-known to be safe and effective (or simply over time).

So how do you know which skincare ingredients are safe? And which ones should be avoided at all costs? In this guide, we'll go through everything you need to know about skincare ingredients so that your next purchase is as informed as possible!

The Good: Vitamin C

Vitamin C is an antioxidant. It's also one of the most powerful antioxidants out there--so powerful that it can actually help reduce the appearance of wrinkles and fine lines.

Vitamin C has been shown to protect against free radicals, which cause oxidative stress on your skin. This can lead to premature aging, but thankfully vitamin C helps repair damage done by these free radicals so that you look younger for longer!

The Percentage for Safe Usage: The concentration level's ideal range is between 10% and 20%. For optimal effectiveness, you absolutely require a concentration higher than 8%. But, going over 20 percent may irritate you and has no added value.

The Bad: Parabens
Parabens are a class of chemicals added to skincare products to help preserve them. They were first used in the 1920s and are found in everything from lotions to makeup.

Parabens may be an issue for you if you're sensitive to them or have an allergy to paraben-containing products; otherwise, there's no reason not to use products with this ingredient in them. In fact, some studies have shown that parabens can actually be beneficial for your skin--especially when used in small amounts (like those found in cosmetic formulas). But if you want something without parabens altogether and would rather not risk sensitization reactions or allergic reactions on top of everything else we've covered here today... then consider looking into non-paraben alternatives!

The Good: Hyaluronic Acid
Hyaluronic acid is a natural substance that's found in your skin. When you're young, it helps to keep your skin supple and plump by holding water inside of the cells of your epidermis (the top layer of skin). As we age, hyaluronic acid levels decrease; this can lead to dryness and fine lines on our faces as well as other parts of our bodies like our hands or elbows.There are many benefits associated with using products containing this ingredient: they help increase hydration while reducing inflammation at the same time! Some products also contain antioxidants that protect against free radical damage caused by UV rays and pollutants in the air around us every day.

The Percentage for Safe Usage: Be on the lookout for concentrations between 0.2 and 0.5 percent; even 1 percent is fairly high. Do a patch test, start low, and work your way up to larger concentrations, as you would with the most active chemicals.

The Bad: Phthalates
Phthalates are used to make plastics more flexible, but they've also been linked to birth defects and hormone disruption. They are common in personal care products like nail polish, deodorant, hair spray, and perfume.

The EWG gives phthalates a rating of 8 out of 10 on its hazard scale (10 being the most hazardous). The FDA says that high exposure levels may cause reproductive harm in males and females alike; however, they don't seem too concerned about low-level exposure from cosmetics or other sources like food packaging materials since there aren't any studies showing any ill effects at these levels--and we all eat food every day.

The Good: Niacinamide

Niacinamide is a form of Vitamin B3, and it's often used in skincare products to treat acne and skin discoloration. It can also help with anti-aging because it promotes collagen production and helps reduce inflammation.

Niacinamide is safe for most people to use; however, if you have diabetes or high blood sugar levels there are some precautions that need to be taken when using this ingredient. You should be aware of how many niacinamide items you use throughout your routine when it comes to percentages. Niacinamide formulations can temporarily irritate the skin, resulting in redness, sensitivity, itching, and burning when used in excess or layered.

The Percentage for Safe Usage: Consider these recommendations when deciding whether niacinamide concentration is best for you.
  • 2% or less: This is too little. You might not notice how using the product benefits you.
  • 2% to 3%: Managing acne and oil production
  • 3% to 6%: Reducing hyperpigmentation and lackluster skin, as well as improving tone, texture, and the overall skin barrier.
  • More than 7%: This is excessive and could irritate your skin, especially if you already have sensitive skin.

The Bad: Formaldehyde and Formaldehyde-releasing ingredients
Formaldehyde is a chemical used in the manufacture of many things, including plastics and fabrics. It's also used as a preservative in some skincare products, including nail polish. Formaldehyde can cause irritation and allergic reactions. This can be especially problematic for people with sensitive skin, who may not know that they're reacting to the formaldehyde until it's too late.

If you have any reason to suspect that your product contains formaldehyde or other similar chemicals--such as diazolidinyl urea or imidazolidinyl urea--check the ingredients list before using it again on yourself or anyone else.

The Good: Retinol

Retinol is a form of vitamin A that helps with wrinkles, acne, and skin discoloration. It's found in many different skincare products, including moisturizers and serums. If you use too much retinol without sunscreen or without being careful about wearing SPF during the day (and even at night), it can cause irritation, redness, and peeling. People with sensitive skin should be cautious when using this ingredient as well.

The Percentage for Safe Usage:

  • Low-strength retinol - 0.01% to 0.03%
    If you have never taken retinol previously, or have dry and sensitive skin, try lower-strength retinol.
  • Moderate-strength retinol - 0.03% to 0.3%
    Try incorporating a stronger product into your regimen: one with around 0.2% retinol is recommended. This will help if you encounter skin issues like uneven skin tone or texture and a noticeable loss of firmness.
  • High-strength retinol - 0.3% to 1%
    Consider using a high percentage retinol cream, serum, or therapy if you have persistent skin issues including severe wrinkles and prominent uneven skin tone. But what percentage of retinol is effective? Try to find formulations with a proportion of between 0.3% and 1%; the most potent choice is retinol at 1%.

The Bad: Polyethylene Glycol Compounds (PEGs)
Polyethylene glycol compounds (PEGs) are a type of plastic that can be found in some skincare products. They're also used in food items such as ice cream and cheese, so you might have already consumed some PEGs without even knowing it!

While there aren't any known negative health effects associated with PEGs themselves, they can cause skin irritation and allergies. While this isn't a huge concern if your skincare routine contains only one or two products containing PEGs, you may want to reconsider using products with high amounts of these ingredients if your skin is sensitive or acne-prone.

The Good: Salicylic Acid

Salicylic acid is a beta hydroxy acid that is commonly used in acne treatments, as well as other skin conditions like psoriasis and seborrheic dermatitis. It works by preventing the buildup of skin cells, reducing inflammation, and loosening blackheads so they can be removed more easily.

It's important to note that salicylic acid can cause irritation if you have sensitive skin (which is why it's often combined with other ingredients). If this sounds like you, you may want to avoid using products with high amounts of salicylic acid on your face until you know how your skin will react.

The Percentage for Safe Usage: Salicylic acid has FDA approval and is safe to use topically in skin care products at concentrations of up to 2%. Salicylic acid concentrations might be higher in professional treatments and chemical peels carried out by a dermatologist or esthetician.

The Bad: Plastic Microbeads
Microbeads are tiny plastic balls used in some skincare products to exfoliate and remove dead skin cells. They are often used as scrubbing agents, but they don't have to be abrasive. Microbeads can also be found in kinds of toothpaste, makeup products, and even clothing fabrics.

Microbeads are so small that they cannot be filtered out of the water by wastewater treatment plants--they end up floating through the environment and into our waterways where they eventually make their way into our food chain through fish who eat them out of curiosity or mistake them for food particles (they look like krill). Once ingested by humans or animals, microplastics will enter your digestive tract where they accumulate toxins from whatever has been stored inside them over time--the same goes for any other pollutants present in our water supply!

Skincare ingredients can be confusing, but they're important. Skincare products contain a lot of different chemicals and ingredients that can affect your skin in different ways. But don't panic! You don't have to throw out all your favorites just yet.

The best thing you can do is educate yourself about what's in the products you use every day and make informed decisions about which ones are worth keeping around (and if so) and how often they should be used. The best way to know which ones are good for you is by understanding what each ingredient does, the potential pros and cons of using it on your skin, and whether or not there might be any side effects associated with its use (like irritation). The next time someone tells you that they're going on a "natural" cleanse because they heard it will help them lose weight or cure cancer? That person probably needs more than just their diet changed--but maybe this article could start them down the right path toward wellness anyway!
