Theobromine — methylxanthine cosmetic active for de‑puffing, firming and microcirculation support.

Theobromine is a methylxanthine cosmetic active inspired by the chemistry of cocoa. It supports microcirculation, antioxidant protection and lipolytic activity to help improve the appearance of puffiness and uneven skin tone.

Functionally related to caffeine, theobromine can contribute to phosphodiesterase inhibition, thereby promoting adipocyte lipolysis and microcirculatory flow in topical applications. It is suited to firming body care, anti‑cellulite treatments and de‑puffing eye products.

Use in leave‑on formulas such as gels, serums and lotions. Combine with synergists (e.g., caffeine, carnitine, peptides). Add in the cool‑down phase to preserve activity.

Usage: Eye gels/serums (de‑puffing), firming/anti‑cellulite body care, slimming gels, antioxidant toners, leave‑on lotions.

How to mix:

- Pre‑dissolve in propylene glycol or butylene glycol (5–10× its weight); mild warming aids dissolution.

- Alternatively solubilize with a suitable co‑solvent system (e.g., ethanol/glycols), then add to the water/glycol phase.

- Add in the cool‑down phase; avoid temperatures > 40°C; target pH 4.0–7.0.

Usage rate: 0.1–2.0%

Product Description: White to off‑white crystalline powder; faint characteristic odor.

Solubility: Sparingly soluble in water; soluble in glycols and ethanol with warming; use co‑solvents/solubilizers as needed.

Storage: Keep tightly closed in a cool, dry place; protect from light. Prefer refrigerated storage (2–8°C). Shelf life 24 months unopened.
