The most common complaint about makeup that doesn't last is rarely a product problem. It's a substrate problem. Makeup applied to dehydrated skin, without primer, or over SPF that hasn't fully adhered lasts 2–3 hours. The same makeup on correctly prepared skin lasts 8–12 hours without touch-ups. The difference is in the preparation.

What Preparation Does to Adherence

Dehydrated skin has uneven texture — fine lines absorb product non-uniformly and foundation accumulates in those zones, creating a cakey effect after a few hours. Hydrated skin has a smooth, consistent surface: product applies evenly and adheres stably.

Oily skin without sebum treatment: the sebum skin produces throughout the day dissolves makeup like an emulsifier. Niacinamide that reduces sebum reduces this effect.

The 5-Minute Protocol That Triples Longevity

1. Gentle cleanse — surface free of residue
2. Prebiotic serum — even texture, minimised pores
3. HA gel — hydration that dries in 60 seconds without residue
4. Wait 2 minutes (critical: dry moisturiser = functional primer)
5. SPF50 with tint — even-tone base that serves as a natural primer
6. Foundation or concealer (if needed) — in much smaller quantity

The Primer Mistake

Many primers contain silicones that create a smooth film but repel makeup formulations with high water concentration. The result: makeup applies more easily but slides off after a few hours. Mineral SPF as a base has better adherence for most modern foundation formulations.
