Stock Brightening Formulas Ready for Your Label

Your customers want brighter and more radiant skin today, not six months from now. RainShadow Labs stocks seven brightening formulas with vitamin C and botanical extracts.

Each serum targets hyperpigmentation, uneven skin tone, and discoloration. 

You pick the formula, add your label, then ship to customers. It’s that easy!

Face Serums for Every Customer

Your sensitive skin customers need gentle formulas. Your oily skin clients want lightweight textures. These products cover both.

The vitamin C serums use stabilized forms that won't oxidize quickly. Kojic acid formulas stay white instead of turning brown. Niacinamide serums absorb fast without leaving residue.

Each 30 ml bottle provides about 60 applications. Customers typically reorder every two months with daily use. The dropper bottles make application precise and hygienic.

We Offer 7 Stock Brightening Formulas

These seven formulas give you options for every customer type and skin concern. Each one targets brightening from a different angle.  

You can offer one product or build a complete brightening collection.

FAQs About Wholesale Brightening Serums & Oils

Which vitamin C type works best for stability?

We use both L-ascorbic acid and sodium ascorbyl phosphate. Both stay stable and effective throughout the entire shelf life.

What's the typical reorder timeline for customers?

Most retail customers come back every 6-8 weeks. Spa clients usually order quarterly. We keep stock ready so you never run out.

How many products should I launch with?

Most successful brands start with 3-4 products. Gives your customers a choice without tying up too much cash in inventory.

Do serums work better than creams for brightening?

Serums penetrate deeper because of their smaller molecules. Creams protect and moisturize better. Many brands offer both to give customers options.
