When Skincare Gets Too Complicated: A Dermatologist’s Perspective
Skincare used to be fairly simple. Cleanse, moisturize, maybe sunscreen if you were paying attention. But over the past decade, routines have grown dramatically more complex. Toners, essences, exfoliating acids, and multiple serums layered one after another have turned what was once basic self-care into elaborate product lineups.
In dermatology offices, however, the results of these routines often tell a different story. Instead of calmer, healthier skin, many people are showing up with irritation, breakouts, and compromised skin barriers from using too many active ingredients at once.
Dermatologist Dr. Hallie McDonald, co-founder of the skincare brand ERLY, has seen this shift firsthand. After treating a growing number of patients experiencing reactions from overly complicated regimens, she began thinking more critically about what effective skincare actually needs. Her answer is surprisingly simple: fewer products, thoughtfully formulated, that support the skin barrier rather than overwhelm it.
When More Becomes Too Much
The skin barrier plays a central role in skin health. It protects against environmental irritants, prevents excessive water loss, and helps the skin maintain balance. When the barrier is functioning properly, the skin is calm, resilient, and hydrated.
But when too many active ingredients are layered together, that barrier can quickly become compromised.
“When you layer multiple actives like retinoids, exfoliating acids, and brightening agents, you disrupt the skin barrier,” Dr. McDonald explains. “That can lead to increased transepidermal water loss, redness, stinging, acne, perioral dermatitis, and eczema.”
Ironically, many people respond to these reactions by adding even more products in an attempt to correct the problem.
“I see this every single day,” she says. “Patients come in with adverse side effects from their skincare routines and show me ten different products they’ve been using to try to fix the issue. The solution is often just to simplify everything and go back to basics.”
