ONE/SIZE Beauty B12 Base Thinner Vitamin Pearl Serum

This serum is specifically formulated for liquid and cream foundations. It is not intended for use with powder foundations.

Start by mixing a 1:4 ratio (1 part serum to 4 parts foundation) and adjust based on your desired coverage and luminosity. Experimentation is key to finding your perfect mix.

The serum has a slight pearlescent quality that may subtly alter the shade of your foundation, generally making it appear slightly lighter or more luminous. It is advisable to test the mixture before full application.

The crushed pearls used in the formula are vegan.

Vitamin B12 is included to boost the skin's natural radiance and contribute to a healthier-looking complexion.

While the serum provides a luminous finish, it is designed as a mixing medium to alter foundation formulas. For a standalone luminous effect, other products might be more suitable.

The luminous finish typically lasts as long as your foundation wears, often contributing to a smoother, more radiant appearance throughout the day.

Use less serum in your next mix. Start with a smaller amount of serum and gradually add more until the desired consistency is achieved.

Ensure the serum is thoroughly mixed with the foundation. Try using a slightly larger proportion of serum for a more noticeable glow. Consider applying to well-prepped, hydrated skin.

Ensure both the foundation and the serum are at room temperature. Mix the products thoroughly on a non-porous surface. If separation persists, the specific foundation formula might not be compatible.

Ensure the product is fully blended and allowed to set. If the issue persists, try using a setting powder or a different foundation formula.
