Bos Essentials Ultra Fine Vitamin C Powder 60g — 100% Pure Ascorbic Acid, Cosmetic-Grade, Instant-Dissolve for DIY Serums

Bos Essentials Ultra Fine Vitamin C Powder is a 100% pure, cosmetic-grade ascorbic acid powder formulated to dissolve instantly for creating fresh DIY serums, toners, and creams.

This ultra-fine Vitamin C powder gives you control over freshness, concentration, and ingredients so you can mix potent topical treatments on demand. Free from fillers and preservatives, the non-GMO, cosmetic-grade ascorbic acid is designed to dissolve smoothly into water, aloe, or hydrosols to form clear, non-gritty serums. Because Vitamin C in solution degrades over time, starting from powder ensures maximum potency at the moment you need it.

How should I mix this powder for a stable, skin-friendly serum?

Begin by measuring by weight for consistent results: 5–10% concentration is a common, skin-tolerant range for facial serums. Dissolve the ultra-fine powder into chilled distilled water, aloe vera gel, or a hydrating base, stirring until fully clear. Refrigerate any prepared serum and use within 2–4 weeks for best performance.

• Suggested concentration: 5% (gentle) to 10% (more potent)
• Mixing bases: distilled water, aloe vera gel, or green tea infusion
• Storage: cool, dry jar for powder; refrigerate mixed serum
• Use window: 2–4 weeks after mixing

Can I combine this Vitamin C powder with other actives like hyaluronic acid?

Yes—Bos Essentials Vitamin C powder pairs well with hydrating actives, such as hyaluronic acid powder, to produce a balanced serum that adds moisture while delivering ascorbic acid. Add hyaluronic acid after the Vitamin C fully dissolves to avoid clumping, and always patch-test combinations to check for sensitivity.

• Layering tip: dissolve Vitamin C first, then add hyaluronic acid
• Combine with soothing bases like aloe to reduce stinging
• Patch-test new blends on a small skin area before full use
• Adjust ratios to personal tolerance and skin type

What makes this product different from premade Vitamin C serums?

Powdered ascorbic acid stays stable for long periods and only becomes active when mixed, so you avoid potency loss that happens in bottled serums over weeks. Because it contains no additives, you control the concentration and complementary ingredients, which can reduce exposure to unnecessary preservatives or stabilizers.

• 100% pure ascorbic acid—no fillers, no preservatives
• Long shelf life as a powder; mix fresh when needed
• Cost-effective: a 60 g jar yields many mixes at chosen strengths
• Cosmetic-grade, non-GMO formulation for topical use

How do I minimize irritation and get the best results?

Start with a lower concentration (around 5%), and gradually increase only if your skin tolerates it. Use gentle, hydrating carriers like aloe vera or hyaluronic acid and avoid combining freshly mixed Vitamin C with strong exfoliants immediately. Always apply sunscreen during daytime use when applying active Vitamin C in your routine.

• Begin at 5% concentration to reduce stinging
• Use soothing carriers: aloe vera, green tea, or hyaluronic acid
• Avoid strong acids or retinoids immediately after mixing
• Store mixed serum cold and use within recommended time

Who is this for: Bos Essentials Ultra Fine Vitamin C Powder is aimed at skincare DIYers, formulators, and budget-conscious users who want full control over concentration, freshness, and complementary ingredients. It's suitable for people who prefer additive-free, cosmetic-grade actives and are comfortable measuring and mixing their own serums or toners. Not intended for internal use; follow topical-only instructions and patch-test if you have sensitive skin.
