Introduction

If you check your personal items, you’ll likely find at least one cosmetic product. To ensure these products are good for your skin, it’s important to follow safe cosmetics tips. From small samples to full makeup sets, cosmetics have become a daily essential that’s easy to find and use.

But here’s something to think about. How much do we really know about the products we use on our skin every day?

In this post, I’d like to share some safe cosmetics tips in a simple Q&A format. I hope this helps refresh some basic knowledge and supports better skincare habits in daily life.

Is Homemade Skincare Always the Safest?

In my experience, homemade skincare isn’t always safe. These DIY cosmetics don’t last very long, especially when made without preservatives. Sometimes, you even have to keep them in the fridge and use them within a week.

Also, if you don’t choose the right ingredients, the product might include things that aren’t great for your skin. I’ve seen cases where people used natural-looking ingredients that were actually not so clean.

Making it properly is also important. If the recipe isn’t followed carefully, it could end up irritating the skin instead of helping it.

I think it’s important to be very careful about the ingredients. For example, pay attention to the way you make it. Also, consider how you store it at home.

Do Fewer Ingredients Mean Safer Skincare Products?

In basic skincare products, we often see ingredients like water, oils, surfactants, moisturizers, thickeners, colorants, preservatives, fragrance, and active ingredients.

Since there are so many different formulas and functions in modern cosmetics. It’s hard to say that fewer ingredients are always better. From what I’ve learned, the ingredients used in cosmetics are generally considered safe for the skin. So, when choosing simple skincare products, the number of ingredients isn’t always the most important thing.

A Korean cosmetic insider said. She personally doesn’t believe that using a large amount of any “good” ingredient is always better. Even good things can be too much sometimes making worse.

Is It Okay to Keep and Use Sample Cosmetics for a Long Time?

Sample cosmetics are not meant to be sold, they’re made to help consumers try a product before buying it. The Ministry of Food and Drug Safety states that selling samples is not allowed by law in Korea. Displaying samples for sale is also prohibited.

These samples are usually given out for free in small amounts. They’re labeled with the product name, the company name, and a note that it’s a tester or not for sale.

In my view, it’s best not to keep sample products for too long. Sample cosmetics have a short shelf life and can expire quickly. They’re meant to be used shortly after receiving them, just to see if the product suits your skin.

Many people prefer testing a sample on the back of their ear. Others prefer the back of their hand rather than directly on their face. I usually wait a day to check if there’s any reaction before deciding to buy the product.

Should You Store Your Cosmetics in the Refrigerator?

Most cosmetics are designed for room-temperature storage usually between 10°C and 25°C. If the environment isn’t too hot or too cold, the product usually stays fine.

However, frequent changes in temperature can affect the quality. For example, if you put a product in the fridge during summer, it’s best to continue storing it there afterward.

I’ve also seen what happens when cosmetics are left in direct sunlight—lipsticks can melt, and creams can separate. In freezing weather, some products might harden. When a product changes in texture or smell, you should think not to use it.

Are All Ingredients in Organic Cosmetics Actually Organic?

The definition of “organic cosmetics” can vary depending on the country and certification body. In Korea, there are specific guidelines for labeling and advertising organic cosmetics. The KCIA states that organic cosmetics usually contain over 95% ingredients derived from animals or plants. At least 10% of the total must be certified organic. In some cases, more than 70% of the ingredients excluding water and salt must be organic to meet the standard.

Organic Cosmetics in Korea are generally made without synthetic preservatives or artificial fragrances. But some small amounts of synthetic ingredients (up to 5%) are allowed when no natural alternatives are available. So, a product is labeled as organic, it doesn’t mean that every single ingredient is organic.

Even if organic cosmetics use high-quality, plant-based ingredients, they might still cause irritation if they don’t match your skin. Therefore, organic or not, the most important thing is to follow safe cosmetics tips that match your skin’s needs.

To me, choosing organic cosmetics is more about trying to reduce artificial chemicals. It is also about supporting the environment, rather than expecting perfect results.

It’s a personal effort—and I think that’s a thoughtful way to look at it.

Does Using Soap Make Your Skin Worse?

Soap usually has a pH level of around 8 to 9, which is slightly alkaline. So, some people are concerned about the effects of alkaline soap on skin health.

From what I’ve seen, using soap causes a neutralizing effect, which usually isn’t a problem for healthy skin.

If your skin is very sensitive, choose milder options. Use baby cleansers or gentle foaming washes if your skin is damaged.

Some people also do double cleansing—using a makeup remover first and then washing with soap. I find this helpful when you’ve worn heavy makeup, applied waterproof sunscreen, or especially dirty after cooking or cleaning.

Should People with Acne Wash Their Face More Often?

A friend of mine told me something important. It’s crucial to find the right cleanser. You also need a washing method that suits your skin.

For acne-prone skin, proper cleansing is important. Breakouts can be linked to a buildup of dead skin cells. They can also be caused by excess oil.

But in any acne cleansing routine, washing too often can actually make things worse. It might dry out the skin too much, make it more sensitive. Even lead to more oil production—which could cause more breakouts.

Conclusion

Cosmetics used around the eyes, lips, and nails all have different instructions depending on the type of product. I think it’s always a good idea to read the usage warnings and instructions carefully before applying them.
