Formulated with non-nano zinc oxide as the sole active ingredient, AELIA provides broad-spectrum SPF 50 protection against UVA and UVB rays.

Non-nano zinc oxide particles are typically >100 nm. These larger particles remain on the surface of the skin and form a reflective barrier. Many studies show minimal to no systemic absorption of zinc from non-nano zinc oxide through intact skin.

Compared to nano zinc or chemical UV filters, non-nano zinc oxide has the lowest likelihood of systemic absorption.

Broad Spectrum means that it shields against both UVA and UVB rays — the full spectrum of solar radiation responsible for premature aging and sunburn.

If a sunscreen in the U.S. says broad-spectrum, it has:

-Proven UVA protection

-Met a strict, measurable critical wavelength requirement

-Passed testing that ensures the formula protects beyond UVB sunburn rays

AELIA was formulated without added fragrance in order to let skin breathe freely and without irritation. Ideal for sensitive skin, it protects without overpowering — just a clean, effortless finish that feels like nothing at all.

This test indicates that a dermatologist supervised safety-in-use and patch testing to confirm AELIA's formula is gentle, effective, and non-irritating. Independent certified research organizations (CRO) testing verified skin compatibility, ensuring that every application meets the highest dermatological standards. Safe, non-irritating, and ready for everyday use.

AELIA's formula underwent a Human Repeat Insult Patch Test (HRIPT) under dermatologist supervision to confirm it’s safe for all skin types. The study demonstrated that the product is non-irritating and non-sensitizing, even with repeated use.

AELIA's mineral SPF was evaluated through an independent laboratory comedogenicity study to confirm it does not clog pores or cause breakouts. Under dermatologist oversight, controlled testing verified that the formula remained non-comedogenic, even with daily application.

AELIA is proudly cruelty-free — never tested on animals at any stage of formulation or production. Every test, from SPF verification to safety-in-use studies, is conducted through ethical, human-based research with certified laboratories. Compassion and care, built into every layer of protection.

AELIA's formula contains no animal-derived ingredients and is developed through fully vegan processes from lab to packaging. Every component — from emollients to emulsifiers — is plant-based and ethically sourced, delivering clean, conscious protection made for modern travelers.

Designed for life on the go, AELIA's 50 mL tube meets all TSA liquid regulations, making it effortless to carry on every flight. Compact, secure, and travel-ready — protection that fits perfectly in a carry-on or flight bag, no compromises required.

SPF is measured by comparing the skin’s response to UV exposure with and without sunscreen application. Small test areas on human volunteers are exposed to controlled doses of ultraviolet light.

The result is expressed as a ratio of the Minimal Erythema Dose (MED)—the smallest UV dose that produces redness—on protected versus unprotected skin:

SPF = MED (protected) / MED (unprotected)
This ensures the labeled SPF value reflects real-world protection against UVB rays that cause sunburn and DNA damage.

This test uses a spectrophotometer (a device that measures how much light a substance absorbs) to determine how well a sunscreen protects against UVA radiation.

In the US, a sunscreen can only be labeled broad-spectrum if its critical wavelength hits 370 nm or higher—proof that it protects against both UVA and UVB.

ISO 24443 is the international standard that defines the exact method for conducting this UVA testing to ensure reliable, comparable results.

Each batch of sunscreen is exposed to high temperatures, humidity, and light for months to ensure the SPF, texture, and color remain unchanged throughout the product’s lifespan. Conducted per ICH Q1A (R2) guidelines at 25 °C/60% RH (long-term), 40 °C/75% RH (accelerated), and freeze-thaw cycles to verify chemical and physical stability.

These tests evaluate microbial resistance using standardized inoculation (USP 51/ISO 11930) across bacteria, yeast, and mold strains. They verify absence of pathogens (e.g., S. aureus, P. aeruginosa, C. albicans) and confirm total aerobic microbial count is within acceptable limits.

They also confirm that our clean, vegan preservatives keep the formula safe and stable—even after repeated use.

Our product tubes are tested for integrity, ensuring no interaction between formula and packaging and preventing leakage during cabin-pressure changes. These tests assess potential migration, pH change, viscosity, and appearance variations after storage and transportation simulation.

Before release, every production run is tested again for SPF accuracy, microbiological purity, and appearance—so every tube performs as consistently as the first. Each production lot undergoes verification of SPF, viscosity, odor, color, and pH before market release.

This is an optional clinical evaluation that determines whether a product blocks pores or causes comedones (blackheads or whiteheads).

The results of this test confirm that:
-It doesn’t clog pores
-It’s suitable for acne-prone or sensitive skin
-It has been evaluated under controlled conditions, not just claimed by marketing
