How many new skincare products can you introduce at once?

First, enter one product at a time. This way, you can see what each product does for your skin. Isolate each new addition by waiting one month between the introduction of any other. Also, before using a product all over your face or body, be sure to test it first with a patch to identify if your skin is compatible. Apply a small amount to a small area, such as the wrist, and see what happens for the next 24 hours.

Harry, I always recommend waiting at least 3 weeks before using a new product. If you haven't used anything new in the last 3 weeks, you can enter it right away. Dana, I meant trying one NEW product at a time. If you buy two new products, for example, add just ONE to your current skincare routine. After 3 weeks, if all goes well, you can continue using that product along with the rest of your skincare routine and add the second one.

And that estimate is based on the assumption that you use the product consistently at least once a day, he explains, which probably won't happen if you regularly change it for other things. While some types of products (such as retinoids or AHAs) may initially be expected to cause irritation, it's not necessarily a sign that the product is doing something good for you. Does it mean that if I used a new product and it really works well for me and I see results in 3 weeks? Switching between products with the same active ingredients, such as switching from one salicylic acid cleanser to another, is less likely to affect your progress. I just bought a Clarins travel kit and I can't wait to try them all, but the last time I tried all the products in one set at a time I had very bad breakouts and it took me years to figure out what the culprit was.

If you also switch from a retinoid to other acne products on different days, you may not see any change for a longer time. In the case of vitamin C, for example, it inhibits the production of the pigment melanin, which takes longer. All that term means is to introduce one product per day, which will allow you to evaluate how your skin tolerates each product and, at the same time, let it adapt. Once you know what you're dealing with, you can look for products that fit your skin type and needs.
