If you’re investing in skincare but still not seeing that healthy, radiant glow, the issue may not be your products—it may be what you believe about them. According to Dr. Amir Karam, a board-certified facial plastic surgeon, some of the most common skincare myths are quietly sabotaging results, even for people who are consistent with their routines.
In a recent Instagram Reel, Dr. Karam broke down five widespread misconceptions that he says regularly hold patients back from achieving real, visible skin improvements. Here’s what you need to unlearn.
Struggling With Sleep? This Rechargeable Sound Machine Is A Total Game-Changer
Myth #1: If Retinol Irritated You Once, You Can’t Ever Use It Again
Many people try retinol, experience redness or peeling, and swear it off for good. Dr. Karam says that’s one of the biggest mistakes. Retinol only works when it’s used long term—and irritation usually means the formulation, strength, or frequency wasn’t right for your skin at that time. Skin can adapt when retinol is introduced slowly, paired with hydration, and used consistently rather than aggressively.
Myth #2: Vitamin C and Retinol Should Never Be Used Together
This myth has been circulating for years, but Dr. Karam clarifies that vitamin C and retinol can work together when used correctly. The key is timing and formulation. Many people use vitamin C in the morning to protect against environmental damage and retinol at night to stimulate skin renewal. When used strategically, the two can actually complement each other rather than cancel each other out.
Myth #3: Fillers and Biostimulators Replace Collagen-Building Skincare
Injectables like fillers or Sculptra may improve volume or appearance, but they don’t replace daily collagen-building skincare. According to Dr. Karam, these treatments don’t do the heavy lifting when it comes to long-term skin quality. Consistent use of proven topical ingredients—like retinoids, antioxidants, and sunscreen—is still essential for maintaining firmness, texture, and glow over time.
Myth #4: Oily Skin Should Avoid Oils
This one surprises many people. Dr. Karam explains that oily skin often lacks proper hydration, which can actually trigger more oil production. The right lightweight oils or lipid-based products can help balance the skin barrier, reduce inflammation, and improve glow—without clogging pores. It’s not about avoiding oils altogether, but choosing the right ones.
Myth #5: You Only Need to Cleanse Once a Day
Cleansing only at night might seem sufficient, but Dr. Karam stresses that washing both morning and night matters. Overnight, your skin accumulates oil, sweat, bacteria, and residue from nighttime products. Skipping a morning cleanse can interfere with how well your skincare absorbs and performs throughout the day.
The bottom line
Dr. Karam emphasizes that glowing, youthful skin doesn’t come from chasing the strongest products or adding endless steps. It comes from using the right active ingredients, in the right combinations, consistently over time. Healthy skin is built through daily habits that compound—not quick fixes or viral trends.
If your skin feels stuck, it may be time to rethink what you’ve been told. Sometimes, better skin starts with letting go of the myths holding you back.
