Cepa Allium (Onion) Bulb Extract
Onion extract is clinically significant in modern dermaceuticals, since its high anti-inflammatory, antimicrobial, and antioxidant effects make it an indispensable ingredient in wound management and hair follicle regeneration. The quercetin and sulfur content of onions help recover skin tissue, encouraging collagen synthesis.
Sounds of Therapeutics
Scar Management: Onion extracts can be added to formulations to help soften hard scar tissue, minimize hypertrophic scars, and reduce pigmentation after acne or surgery.
Hair Revival: The high sulfur content helps reduce hair thinning and strengthens fragile hair shafts by improving the scalp microenvironment.
Antimicrobial: Helps soothe the scalp affected by microbial infections and reduce dandruff formation.
Collagen Support: Encourages proper collagen deposition, helping prevent keloid scarring.
How to Use:
Haircare: Apply the extract or infused oil directly to the scalp. Massage gently in circular motions for 5–10 minutes, leave for about 30 minutes, then wash with a mild shampoo.
Scar Treatment: Apply a small amount (e.g., aloe gel formulation) to the affected area 2–3 times daily. Consistent use for 8–12 weeks is essential for visible improvement.
Topical Only: Though onions are edible, Allium cepa extract for therapeutic use is meant for external application only. Do not ingest concentrated extracts.
Safety Information & Usage Notes
Pro Tip: Perform a patch test on the inner forearm if you have sensitive skin. Mild tingling may occur due to sulfur compounds.
Odor Management: Many formulations are processed to reduce the onion-like odor, though a mild earthy smell may remain briefly.
Sun Sensitivity: When used on facial scars, always apply SPF 30+ sunscreen, as healing skin is more UV-sensitive.
Possible Side Effects
This preparation is generally safe, but some may experience:
