Sturelehub Lactic Acid Powder 10 oz (284 g) Cosmetic‑Grade — Gentle Exfoliant for DIY Masks, Creams & Scrubs

Sturelehub Lactic Acid Powder is a cosmetic‑grade, high‑purity powdered alpha hydroxy acid designed for gentle chemical exfoliation and DIY skincare formulations.

Formulated as a fine, easy‑to‑blend powder, this 10 oz (284 g) lactic acid lets you create customized facial masks, creams, toners and body scrubs with control over concentration and texture. Because it is cosmetic grade and highly pure, it’s suitable for at‑home mixing when used with proper dilution, measuring and patch testing. The powder format reduces preservative needs in certain recipes and allows precise dosing for formulation flexibility.

How do I use this lactic acid powder safely in homemade skincare?

Always dilute lactic acid powder into water, hydrosols, or compatible bases and measure concentration by weight. Start with low concentrations (commonly 2–5% for at‑home products) and perform a patch test on a small skin area before full application. Avoid combining with strong actives without guidance and follow neutralization or pH‑adjustment steps when required by your recipe.

• Weigh powder with a digital scale for precise percent formulations.
• Dissolve into warm distilled water before adding to creams or masks.
• Begin with lower percentages and increase gradually after testing.
• Store in a cool, dry, sealed container away from light and humidity.

What benefits can I expect when I add lactic acid to my products?

Lactic acid works as a gentle chemical exfoliant that helps lift dead surface cells to reveal fresher, smoother skin texture. It is also a humectant, meaning it can help skin retain moisture when correctly formulated. These properties make it a versatile ingredient for improving roughness, dullness and moisture balance in custom skincare.

• Improves surface texture by promoting cell turnover.
• Supports hydration due to its water‑attracting characteristics.
• Helpful in masks, toners, and mild peels when diluted properly.
• Suitable for blending into creams, serums, and scrubs for tailored effects.

How should I store and handle the powder to maintain potency?

Keep the lactic acid powder in a tightly sealed container in a cool, dry, dark place to prevent clumping and degradation. Use clean, dry tools to scoop or weigh the powder, and always reseal the container promptly after use. Proper storage preserves purity and makes formulations more predictable over time.

• Use a moisture‑resistant, airtight jar or bag for storage.
• Avoid direct sunlight and temperature extremes.
• Label container with concentration and date opened for tracking.
• Discard if the powder shows discoloration or unusual odor.

Can I combine this lactic acid with other common DIY actives?

Yes, but compatibility depends on pH and the other active’s sensitivity—some combinations can increase irritation or reduce effectiveness. Avoid pairing high concentrations of multiple acids or mixing with strong vitamin C derivatives or retinoids without testing. When in doubt, formulate one active at a time and patch test.

• Compatible with many humectants and emollients when pH is adjusted.
• Exercise caution combining with other AHA/BHA acids or potent retinoids.
• Adjust recipes to maintain a safe, skin‑appropriate pH (commonly 3–4 for AHAs).
• Patch testing is strongly recommended after reformulation.
