How to use skincare creams safely?

According to research published worldwide, the failure to use sunscreen properly and thoroughly will lead to failure in treating melasma.

In modern dermatology, cosmeceuticals are playing an increasingly important role and are widely used, providing high therapeutic efficacy in a number of conditions such as atopic dermatitis (eczema), psoriasis, acne, facial melasma, post-inflammatory hyperpigmentation, and irritant dermatitis of the face.

Without cosmeceuticals for treatment and care, the effectiveness of treatment will be significantly reduced, and both doctors and patients will lose the opportunity to achieve high treatment outcomes.

For example, the role of moisturizing the skin is crucial in atopic dermatitis, and cosmeceuticals are products that help achieve this, or evaluating the role of sunscreen in treating melasma.

According to research published by dermatology hospitals worldwide, failure to protect against sun damage and use sunscreen properly and thoroughly will lead to treatment failure for melasma.

To ensure safety and avoid unwanted side effects, before applying to the intended treatment area (especially the face), it is recommended to apply a small amount to the inside of the arm for 24-72 hours. If there is no reaction, then it is advisable to use the product. Ideally, a skin test using the PUT (Provocative Use Test) or ROAT (Repeat Open Application Test) method should be performed: this method identifies delayed reactions to cosmetics.

Apply the cosmetic product to a small area of ​​skin (about 5cm) on the inside of your arm twice a day (for 2 weeks) to determine the reaction. If, after this time, the treated area shows no signs of reaction (such as itching, redness, blisters, etc.), it indicates that your skin is not allergic to that cosmetic product.

After applying any cosmetic product, if you notice any rash, itching, or redness on your skin, stop using it immediately. Rinse thoroughly with running water to remove the product. Usually, after you stop using the cosmetic, these symptoms will gradually subside and disappear completely.

However, some people may experience worsening allergies and require treatment. In such cases, they should seek medical advice from healthcare professionals.
