When it comes to preserving a beautiful complexion, many of us are willing to spend big bucks on a potent mix of lotions, serums and treatments that promise to fight the signs of aging. But do we actually need to drain our bank accounts to put our best face forward?

As it turns out, drugstore skin care products are often just as just as good as their more expensive counterparts. "There are many factors when it comes to determining the price of a product -- ingredients, quantity and testing," says Hayley Hoffman, a former cosmetic chemist for Skinn Cosmetics, who adds that slick marketing campaigns and pretty packaging can also boost a product's price. "So, bigger price does not always mean better product."

And many dermatologists can attest to that fact, which is why we tapped top doctors to share their picks for best drugstore skin care products. After all, who better to recommend their picks for budget-friendly beauty finds than the professionals who understand the ingredients and science behind why affordable skin care products actually work? Here, the dermatologist-approved drugstore anti-agers that'll save your skin (and your wallet).

"I love 40 Carrots Carrot and C Vitamin Serum, $13.99, because it contains antioxidants and retinol -- the best combo. The antioxidants help fight off free radical damage, while retinol increases collagen production and decreases its breakdown. The serum is highly concentrated and easy to layer." --Dr. Mona Gohara, MD

"I'm a big fan of Lierac Micellar Cleansing Water, $24. It's very effective for removing makeup without drying out your skin or causing any irritation. It contains chamomile, which is extremely soothing to the skin. It also contains hyaluronic acid, which is very hydrating and white lily, which gives it a lovely scent." --Dr. Debra Jaliman

"I love Bioré's One Minute Self-Heating Mask -- it works wonders on pores! Once you apply it, it warms up to open up pores, and in less than a minute, it works to dissolve dirt, oil and toxins and then rinses them away without stripping the skin's natural oils. It leaves your skin looking luminous and fresh. The heat-up aspect is not only relaxing, but also works really well to open up the pores and give them a deep clean." --Dr. Whitney Bowe, MD

"I am a fan of CeraVe Skin Renewing Cream Serum, $16.99. It has encapsulated retinol, which allows a slower delivery into the skin. This helps reduce irritation from retinol. It also contains a ceramide complex and helps hydrate the skin. I recommend using it at night. It's great for blemish-prone skin, as well as dry skin or skin starting to show signs of wrinkling or sun damage." --Dr. Tabasum Mir, MD
