Alpha-Bisabolol
Alpha-bisabolol, also known as α-bisabolol or levomenol, is a naturally occurring monocyclic sesquiterpene alcohol primarily extracted from the essential oil of chamomile (Matricaria recutita) and the bark of the candeia tree (Eremanthus erythropappus). It is widely recognized in skincare for its potent anti-inflammatory, antimicrobial, and soothing properties, making it a common ingredient in cosmetics to calm irritated skin, reduce redness, and support skin barrier function. Alpha-bisabolol has been studied for its therapeutic potential in dermatological applications, including alleviating symptoms of atopic dermatitis and promoting skin healing.
What is it Made of?
Alpha-bisabolol’s chemical formula is C₁₅H₂₆O. Here’s how it’s typically sourced or produced:
-
- Natural Sources:
- Plants: Primarily isolated from chamomile flowers, where it constitutes a major component of the essential oil, and from the wood of the candeia tree; it can also be found in other plants like Vanillosmopsis erythropappa.
- Synthetic Production:
- Commercially, alpha-bisabolol is often biosynthesized using engineered microorganisms like Saccharomyces cerevisiae or Komagataella phaffii for efficient, sustainable production, or through chemical synthesis to ensure purity and consistent supply for skincare formulations.
- Natural Sources:
In cosmetic formulations, nature-identical alpha-bisabolol is commonly preferred for its consistent efficacy and reduced allergen risk.
Best Skin Type for Using It:
Alpha-bisabolol is highly versatile and gentle, making it suitable for a broad spectrum of skin types:
-
- Sensitive Skin: Its anti-inflammatory and soothing effects make it ideal for sensitive or easily irritated skin, reducing redness and calming reactions.
- Irritated or Inflamed Skin: Effective for conditions like atopic dermatitis, rosacea, or post-procedure irritation due to its ability to attenuate pruritus and inflammation.
- Acne-Prone Skin: Helps reduce inflammation and microbial activity associated with acne without exacerbating oiliness.
- Dry Skin: Supports skin barrier function and hydration, aiding in moisture retention for dry or dehydrated complexions.
- Mature Skin: Contributes to anti-aging by improving skin texture, reducing hyperpigmentation, and promoting a more even tone.
- Oily or Combination Skin: Non-comedogenic and lightweight, it can be incorporated without adding excess oil when formulated appropriately.
- Damaged Skin: Beneficial for healing minor wounds, sunburns, or environmental damage through its reparative properties.
Benefits of Alpha-Bisabolol
Here’s an in-depth look at the benefits of alpha-bisabolol in skincare:
Soothing and Anti-Inflammatory
