The amount of time it takes to notice a change in your skin from topical products can vary depending on several factors, including the specific product you're using, the condition of your skin, and how frequently you're using it.
In general, it can take anywhere from a few days to a few weeks to notice a change in your skin from topical products. For example, if you're using a product to address acne, you may notice a reduction in breakouts within a few days of using it. However, if you're using a product to address hyperpigmentation or fine lines, it may take several weeks or even months to notice a visible improvement.
It's important to note that consistency is key when it comes to topical products. You may not see results if you only use a product sporadically. For best results, follow the instructions on the product packaging and use it as directed. If you're not seeing results after several weeks of consistent use, you may need to adjust your skincare routine or consider a different product.
