The question: Is it bad to use products from different lines in conjunction with each other (e.g., one type of shampoo with a different brand of conditioner)?
The expert: Gilbert Soliz, Sephora Pro lead artist
The answer: Beauty brands generally like to market and sell their products as a package, but there's no reason that their products must be used together. In fact, Soliz encourages consumers to test and try different brands to find out what works best for them.
"I find that mixing products from different brands can be essential if you want to achieve the best results for your skin type," he says. "It's more important to focus on the product's formula and ingredients, along with your particular skin type and concern, rather than the brand name."
So how do you prioritize which products to splurge on and which products you can get at the drugstore? Soliz suggests speaking to the salespeople at a shop like Sephora—or to your dermatologist—to determine what your biggest concerns are and what you should look for in your beauty regimen. Then, compare the size, quality, and price of products that target those issues. "Oftentimes, high-end products have the same exact ingredients as the products from a less expensive brand," says Soliz.
