When it comes to skincare, it’s not just about which products you use, but how you use them. Understanding the art and science of layering can make all the difference in achieving that glowing, healthy skin we all desire. At iLM Skincare, we believe in educating our customers, so they can make the best decisions for their skin. In this article, we’ll delve into the common skincare ingredients that may not play well together.

1. Retinol and Vitamin C

Both retinol and vitamin C are powerhouses in skincare. They help to promote collagen production, fade dark spots, and improve skin texture. However, using them together can reduce their effectiveness and even cause skin irritation. It's best to use retinol at night and vitamin C in the morning for optimal results.

2. Benzoyl Peroxide and Retinol

If you're battling acne, you might be tempted to combine these two. However, when used together, they can severely dry and irritate the skin. Instead, alternate their usage, applying benzoyl peroxide in the morning and retinol at night.

3. Alpha Hydroxy Acids (AHAs) and Vitamin C

Both AHAs and vitamin C can exfoliate the skin and promote cell turnover. But layering them can lead to increased sensitivity and redness. Like with retinol, it's best to use vitamin C in the morning and AHAs in the evening.

4. Vitamin C and Niacinamide

While there's some debate about this combination, some experts suggest that mixing vitamin C (an acid) with niacinamide can cause niacinamide to convert into niacin, which can result in redness and flushing. To be on the safe side, use them at different times of the day.

5. Salicylic Acid and Retinol

Salicylic acid, commonly found in acne treatments, can cause irritation when used with retinol. If you wish to use both, ensure that you provide ample time between their applications.

Pro Tips from iLM Skincare:

• Always conduct a patch test when trying a new combination of products.
• Remember that everyone’s skin is unique. What irritates one person’s skin might be fine for another.
• Always prioritize sunscreen in the morning, especially if you're using exfoliants or retinol at night. Protecting your skin from UV rays is crucial.
