Science of Beauty: Why Use Mandelic Acid for Acne to Anti-Aging

· 5 Comments

Acne is the most common skin condition in the United States. 
No acne treatment overview would be complete without Mandelic Acid. 

Retinol is still the gold standard for acne. But peeling acids are more common in acne and acne scar treatment. And Mandelic Acid is an ingredient worthy of your attention. It gets the results of a robust acid but with little to no skin irritation.

WHAT IS MANDELIC ACID?

Mandelic acid is a natural ingredient that comes from bitter almonds

Mandelic acid is a very gentle AHA (Alpha Hydroxy Acid).

Mandelic acid penetrates the skin slowly, making it suitable for even sensitive skin. While it is an “acid” it is very gentle and rarely causes skin irritation.

Mandelic acid is natural, clean, green, and skin-friendly.

It is useful in organic skin care product formulations.

HOW MANDELIC ACID WORKS: ACNE TO ANTI-AGING

Mandelic acid accelerates cell turnover by dissolving the tiny bonds that hold skin cells together. This microexfoliation accomplishes several skincare objectives.

ACNE

Mandelic acid is useful in acne treatment. Mandelic acid removes bacteria-trapping dead skin, which contributes to acne formation. Dead skin also dulls the complexion and makes fine lines look worse. Removing dead skin cells brightens skin. It is anti-bacterial, anti-fungal, and anti-inflammatory. If you have adult acne, Mandelic acid is ideal to treat both acne and signs of skin aging. (1)

ANTI-AGING

Mandelic acid an appealing ingredient within anti-aging products. Mandelic acid is helpful for smoothing mesh-like pattern wrinkles. Mandelic acid promotes collagen production. More collagen increases skin’s elasticity and youthful appearance. Collagen counteracts sun damage by smoothing and refining the skin surface. Sun damage is the largest cause of visible signs of aging.

Mandelic acid reduces hyperpigmentation. It lightens acne scars, sun damage, and age spots.

MANDELIC ACID VS GLYCOLIC ACID

Both acids are highly effective at causing rapid cell turnover. Both reveal younger, smoother, brighter skin. Both acids dissolve the “glue” holding dead skin cells. Both remove dead skin cells without forceful scrubbing. Both Mandelic Acid and Glycolic Acid are ideal for skin unable to tolerate harsh exfoliants.

A difference between the acids is that Mandelic acid has a larger molecular structure than glycolic acid. Smaller molecular structures penetrate the skin faster and deeper.  (2) If the skin can tolerate glycolic, that’s great. But if the skin gets irritated by Glycolic acid, Mandelic acid is an ideal option. The larger molecular structure of Mandelic Acid gets the job done, albeit a tad slower. Mandelic is kinder to the skin. There is little to no irritation and redness with regular Mandelic Acid use. (3)

MANDELIC ACID TIPS FOR BEST USE

  • Skin using AHAs, including Mandelic Acid, is more sensitive to light. Always wear sunscreen
  • To avoid irritation, choose products with 10% or less Mandelic Acid concentrations

HYPERPIGMENTATION

Some hyperpigmentation fading ingredients work best on pink undertone skin. Mandelic Acid works on the hyperpigmentation of all skin tone types. Mandelic Acid inhibits melanin production in existing scars, age spots, and acne marks. (4) This reduces hyperpigmentation of all types on all skin tones.

Mandelic Acid: A Holy Grail Ingredient

Mandelic Acid earns our “Holy Grail Ingredient” rating. It reduces sun damage, acne, and hyperpigmentation. It gently exfoliates and improves skin texture. It works on all skin tones and textures, including mature and sensitive skin. It is natural and suitable for organic product formulations. A Style Chicks skincare superstar!

The Science of Beauty: Can Tamanu Oil Really Help Scars & Stretch Marks?

· 5 Comments

When we hear there’s an organic oil that can be used for skin concerns such as anti-aging, acne, stretch marks, scars, razor burn, bug bites, and can be used for softer, smoother hair, we’re interested. But we are also skeptical. What does the research say? Anecdotal evidence supports beautiful hair and skin on those who use Tamanu Oil. Many people swear by Tamanu Oil for clearing up acne or fading an old scar. But does science back the Tamanu Oil folklore? What is Tamanu Oil? And how do you use it? We did Tamanu Oil Research.

ABOUT TAMANU OIL

The locals call it “Green Gold”. Pacific island folk medicine uses Tamanu Oil for a host of natural remedies. In Southern India, Tamanu Oil is used for many skin ailments. In Taiwan, it is used for hair. Tamanu Oil has gained attention because of its’ rare beauty benefits. The oil comes from a nut of the Tamanu Tree. The Tamanu Tree is commonly found in Polynesia. Within the region, Tamanu Oil is prized for hair, skin and a host of medical uses. Ample anecdotal evidence exists for these uses. Countless people swear by Tamanu Oil. But there have been limited research studies on Tamanu Oil efficacy. Studies to date show a promising organic oil with many versatile uses.

What do we know about Tamanu Oil?

While used for years in Polynesian regions, Tamanu Oil is only a recent discovery to many of us.

Tamanu oil is a topical healing agent that is:

  • antineuralgic
  • anti-inflammatory
  • antimicrobial
  • antibiotic
  • anti-oxidant

TAMANU OIL RESEARCH STUDIES

Tamanu Oil has been long associated with many health and beauty benefits. Research studies are still developing for the documentation of several promising medical uses. There is even research into Tamanu Oil’s potential benefit for cancer and HIV.(1)

But other Tamanu Oil uses are already well documented. These areas include the healing of burns and skin diseases. (2)

Tamanu Oil is both anti-inflammatory and antiseptic. Tamanu Oil is used for skin conditions such as:

  • acne scars
  • burns
  • dry scalp
  • eczema
  • mosquito bites
  • psoriasis
  • stings
  • stretch marks
  • flaky, scaly or dry skin.

Older stretch marks are notoriously difficult to treat. What would make Tamanu Oil more effective than any other remedy?
Its’ rare fatty acid profile.

RESEARCH: HOW TAMANU OIL HEALS SCARS & MARKS

There has been studies of the healing properties of Tamanu Oil. Of interest is the special fatty properties of Tamanu Oil. These fatty properties help soften wounds, scars and stretch marks.

Organic Tamanu oil has a unique fatty acid profile. It has an unusual fatty acid called calophyllic acid. There are few studies on Calophyllum (calophyllic acid). But studies do exist, and there are enough to give credence to the skin healing ability of Tamanu Oil. Various studies verified the wound healing, safety, and antibacterial properties of Calophyllum (3). This supports the anecdotal reports of the skin improvement seen with the traditional use of Tamanu Oil for at least scars, burns, and stretch marks.

CONCLUSION

Tamanu Oil is an exciting and promising Oil for a host of topical and medical uses. Tamanu Oil research is still limited. But studies are still in development to further explore potential benefits. What we do know is that Tamanu Oil is effective on several skin conditions and treating damaged skin.

WARNING: Tamanu is a nut. Tamanu oil should be avoided by those with nut allergies.
