"Is This Normal?" Guide

Select an observation about your makeup to read general educational guidance.

Change in smell: If a product develops a sour, stale, or unusual odor, it may indicate that the ingredients (particularly oils) have gone rancid or the preservative system has failed. It is generally advised to discard the product.
Change in texture: Products that become clumpy, unusually thick, or develop a chalky film may have degraded. This can affect application and safety. Consider replacing the product.
Colour change: Oxidation or a shift in the intended color can occur over time as ingredients react with air and light. This often signals that the product is past its optimal shelf life.
Product separation: While slight separation can sometimes happen in natural formulas (requiring a shake), persistent separation of liquids and oils often means the emulsifiers have broken down. The product may no longer perform or protect correctly.
Damaged packaging: Cracked lids or broken pumps expose the formula to excessive air, moisture, and bacteria, rapidly accelerating degradation.
Unexpected irritation: Stop using the product immediately if it appears to be causing redness, swelling, or discomfort. If the reaction is severe, persistent, or concerning, seek appropriate medical advice.

10 Makeup Mistakes People Commonly Make

Unwashed brushes harbor oils and debris, leading to poor application and potential skin congestion.
Heavy layers can suffocate the skin barrier and look unnatural. Building thin layers is more effective.
Continuing to use makeup that has changed in smell or texture risks exposing skin to degraded formulas.
Sharing items, especially around the eyes and lips, easily transfers microbes between individuals.
Keeping makeup in a damp bathroom or hot car accelerates the breakdown of the formula.
Using a lip liner on the eyes may be unsafe, as eye-area cosmetics have stricter colorant regulations.
Covering an active rash or severe breakout can trap irritants and delay healing.
Sponges in particular need thorough drying and washing to prevent mold growth.
Leaving cosmetics on overnight traps daily grime and limits the skin's natural recovery process.
If a product consistently causes stinging or redness, it should be removed and discontinued.
