The Claim
"If your skin is oily you should skip moisturizer to avoid making it worse."
The Science
This is one of the most damaging skincare myths, and it leads to a vicious cycle of worsening oil production. When you strip your skin of moisture — either by skipping moisturizer or over-cleansing — the skin's barrier function is compromised. In response, your sebaceous glands ramp up oil production to compensate for the perceived lack of hydration.
The result is skin that feels even oilier than before, which leads people to strip it further, creating a feedback loop. Dermatologists consistently recommend that oily skin types use a lightweight, oil-free moisturizer to maintain barrier integrity and actually regulate sebum production.
Look for gel-based or water-based moisturizers containing ingredients like niacinamide, which has been shown to reduce sebum production, or hyaluronic acid, which hydrates without adding any oiliness. The goal is to hydrate the skin without occluding pores.
Key Takeaway
Skipping moisturizer causes the skin to overproduce oil to compensate. Lightweight oil-free moisturizers actually help regulate sebum production.
