When it comes to skin care, there are a number of common mistakes that can hamper the effectiveness of your routine and harm the health of your epidermis. Here are nine common mistakes to avoid to optimize your skin care routine.

1. Neglecting proven ingredients

It's tempting to try out new products boasting revolutionary ingredients claimed to be superior to retinol or vitamin C. However, these claims are often based on in vitro studies, whose effectiveness on human skin is not always proven. It is therefore advisable to focus on active ingredients with proven efficacy, such as retinol, vitamin C or copper peptides, while remaining open to moderate experimentation with new ingredients.

2. Rely blindly on marketing claims

Promises of immediate results can be misleading. Some products offer instant effects, but most active ingredients require several weeks, even months, to show visible results. Patience and regularity are essential to assess a product's real effectiveness.

3. Apply inappropriate quantities of products

Use excessive amounts of retinol or exfoliating acids does not accelerate the benefits and can cause irritation. Conversely, insufficient application of sunscreen reduces its ability to protect the skin effectively. It's crucial to respect the recommended dosage for each product.

4. Keeping expired products

Using products beyond their expiration date can reduce their effectiveness and increase the risk of irritation or infection. Retinol serums, for example, should be discarded after 3 to 4 months, especially if not kept refrigerated. Jarred creams can also become contaminated over time.

5. Multiply the products in your routine

An overloaded routine can overwork the skin and reduce the effectiveness of active ingredients. It's best to concentrate on a few well-chosen products, adapted to your skin type and specific needs, to avoid negative interactions and irritation.

6. Combining incompatible assets

Certain combinations of active ingredients may cancel each other out or irritate the skin. For example, retinol should not be used in immediate conjunction with vitamin C or fruit acids, as differences in pH can alter their effectiveness. We recommend spacing out their application or using them at different times of the day.

7. Ignore ingredient list

It is essential to check the presence and concentration of the active ingredients promoted by cosmetic products. Terms such as "pro-retinol" may refer to less effective derivatives of retinol. What's more, some products feature ingredients in minute quantities, insufficient to deliver the expected benefits.

8. Not adapting your routine to skin changes

Skin's needs evolve with age, the seasons and environmental conditions. It's important to adjust one's routine accordingly, modifying the products and active ingredients used to meet new skin requirements.

9. Have unrealistic expectations

Cosmetic treatments contribute to the health and appearance of the skin, but they cannot replace medical treatments for severe conditions or completely reverse the advanced signs of aging. A realistic approach, combined with a healthy lifestyle, is essential to achieve satisfactory results.

By avoiding these common mistakes, you'll optimize the effectiveness of your skincare routine and promote the health and radiance of your skin.
