Full Job Description

Skincare, Cosmetics & Wholesale Ingredients
Position Overview

We are seeking a motivated Beauty Sales & Business Development Intern to join our skincare, cosmetics, private-label manufacturing, and wholesale ingredients company.

This is a 12-week, in-person internship designed for college students approaching graduation, recent graduates, and entry-level candidates who are interested in beginning a career in sales, business development, skincare, cosmetics, or the beauty industry.

The internship is intended to provide hands-on training while allowing both the intern and the company to evaluate whether there may be a strong long-term employment fit.

Interns who demonstrate excellent performance, professionalism, reliability, communication skills, and sales potential may be considered for a full-time position after completing the internship. However, successful completion of the internship does not guarantee employment. Any future offer will depend on the intern’s performance, available positions, business needs, and overall fit with the company.

About the Company

Our company helps bring beauty and personal-care product ideas to life through private-label manufacturing, custom formulation, wholesale ingredients, and product development.

We work with beauty brands, entrepreneurs, retailers, spas, laboratories, and other businesses to create skincare and cosmetic products that are sold in the market today. Our services support the product-development process from the initial idea and ingredient selection through formulation, manufacturing, packaging, and finished production.

Internship Schedule

Duration: 12 weeks
Location: In person
Business hours: 11:00 a.m. to 5:00 p.m.
Required availability: A minimum of four days per week
Candidates must be able to maintain a consistent weekly schedule throughout the internship.

Specific working days will be discussed during the interview and confirmed before the internship begins.

Internship Experience

Interns will gain practical experience in B2B sales, business development, customer communication, wholesale supply, private-label manufacturing, and the beauty industry.

You will work alongside our team and learn how to communicate with prospective customers, understand their product needs, follow up on business opportunities, prepare product information, and support the sales process.

This internship emphasizes training, professional development, accountability, and real-world business experience. Interns will also have the opportunity to earn commission on qualifying sales they directly generate, according to the company’s commission structure.

Responsibilities

Assist with customer outreach and lead follow-ups
Communicate professionally with prospective and existing customers
Help organize emails, customer lists, leads, and sales records
Support the preparation of product information, quotes, and sales materials
Assist with responding to general customer inquiries
Conduct market, customer, product, and competitor research
Learn about skincare ingredients, cosmetic products, private-label manufacturing, and wholesale supply
Support business-development and customer-retention activities
Participate in team meetings, sales training, and performance reviews
Maintain accurate records of customer communications and follow-up activities
Help identify brands, businesses, and entrepreneurs who may benefit from our products and services
Follow company policies regarding confidentiality, pricing, professionalism, and customer information

Qualifications

Current college student approaching graduation, recent graduate, or entry-level professional
Interest in sales, business development, beauty, skincare, cosmetics, entrepreneurship, or wholesale supply
Strong verbal and written communication skills
Professional, dependable, organized, and willing to learn
Comfortable communicating through email and phone
Basic knowledge of spreadsheets, email platforms, and data entry
Ability to follow instructions and maintain accurate records
Comfortable working toward sales goals and follow-up expectations
Positive attitude and willingness to accept coaching and feedback
Ability to commit to the full 12-week internship
Availability to work in person at least four days per week between 11:00 a.m. and 5:00 p.m.
No prior beauty-industry or sales experience is required; training will be provided

Preferred Fields of Study

Students and graduates from the following areas are encouraged to apply:

Business Administration
Marketing
Sales
Communications
Entrepreneurship
Cosmetic Science
Chemistry or Biology
Fashion or Beauty Industry Studies
Supply Chain or Operations
Related fields

Candidates from other educational backgrounds may also be considered if they demonstrate a strong interest in the position.

Compensation

This internship includes the opportunity to earn commission on qualifying sales generated by the intern.

Commission eligibility, rates, calculation methods, payment timing, and applicable conditions will be explained during the interview and onboarding process.

The commission structure provides interns with direct exposure to a results-oriented sales environment in which communication, consistency, follow-up, relationship building, and performance can contribute to their professional and financial growth.

Potential Full-Time Career Path

This internship is intended to serve as a possible entry point for candidates who are interested in building a career with the company.

High-performing interns may be considered for future full-time opportunities such as:

Sales Representative
Business Development Representative
Account Coordinator
Account Manager
Customer Relationship Specialist
Private-Label Sales Specialist
Wholesale Ingredients Sales Representative

A full-time position is not guaranteed. Employment decisions will be based on the intern’s performance throughout the 12-week program, attendance, reliability, professionalism, communication skills, sales ability, available openings, and the company’s staffing needs.

What We Are Looking For

We are looking for candidates who are serious about beginning their careers and are interested in more than completing a temporary internship.

The ideal candidate wants to learn, improve, accept responsibility, develop professional sales skills, and potentially grow into a long-term position with the company.

Training will be provided. We value motivation, professionalism, consistency, communication, reliability, and a genuine willingness to learn.

Pay: $500.00 - $5,000.00 per month

Work Location: In person
