How to Best Use Mandelic Acid for Acne to Aging

July 1, 2019 · 5 Comments

Acne is the most common skin condition in the United States, and no acne treatment 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 natural ingredient that is extracted from bitter almonds

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

It 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.

It is natural, clean, green, and skin-friendly.

It is useful in organic and clean beauty skin care product formulations.

HOW MANDELIC ACID WORKS: ACNE TO ANTI-AGING

It works by accelerating cell turnover by dissolving the tiny bonds that hold skin cells together. This microexfoliation accomplishes several skincare objectives.

ACNE

It is an exceptionally effective acne treatment.

It 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, products with Mandelic acid in their formulations is ideal to treat both acne and signs of skin aging. (1)

ANTI-AGING

It has excellent anti-aging properties.

It is helpful for:

  • smoothing mesh-like pattern wrinkles
  • 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.
  • reducing 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 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.

It’s larger molecular structure gets the job done, albeit a tad slower. But you won’t have to skip a day due to irritation like sometimes occurs with retinol.

Mandelic is kinder to the skin. There is little to no irritation and redness with regular use. (3)

MANDELIC ACID TIPS FOR BEST USE

  • Skin using any AHA 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.

It 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

A “Holy Grail Ingredient”!

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.

5 Things You Should Know Vitamin K + Dark Undereye Circles

June 24, 2019 · 6 Comments

Vitamin K INGREDIENT GUIDE is an overview of treating dark circles with Phytonadione.

Why K Works for Dark Undereye Circles

Vitamin K, is popular in under-eye creams because it can lighten infraorbital darkness, AKA under eye circles.

Vitamin K is also called Phytonadione on ingredient listings.

Phytonadione is most beneficial for dark circles with a blue or brown undertone.

This kind of dark under eye circle has a vascular component. They are known as “vascular dark circles” because leaking capillaries.

The trapped blood pools in the skin tissues and appears blue or purple once trapped. Over time, as it absorbs and settles, it appears a mid to dark reddish brown, like a bruise.

5 Things You Should Know about Vitamin K

  1. Vitamin K reverses the calcium deposits in elastin fibers. These deposits harden and cause wrinkles.
  2. Phytonadione helps with blood coagulation and circulation.
  3. Some dark circles are caused by weak vessels that allow blood near the surface of your skin. These circles have a blue, purple or brown undertone.
  4. Topical application of Phytonadione cream prior to an in-office procedure strengthens blood vessels. Stronger blood vessels means less bruising after surgical or laser treatments.
  5. As we age, we tend to get more broken capillaries. Vitamin K strengthens these capillaries so they are more resistant to breakage.

What to look for in a Vitamin K Topical

Vitamin K is most effective as part of a team instead of a standalone K cream or gel.

A study in the Journal of Cosmetic Dermatology showed topical Vitamin K works best when paired with retinol, Vitamins C, E, and the Bs. (1)

What to Know About Vitamin K and Retinol

If you use prescription retinol, apply the retinol first and then the topical K product.

What Percentage of Vitamin K is Most Effective?

In order to get Vitamin K benefits, choose a product with enough Phytonadione in the formula to be effective.

The study mentioned above used a 2% Phytonadione concentration when used with retinol, Vitamin C, and similar actives to treat dark circles.

The study showed good effect on strengthening blood vessels to stop future leaking and darkening. But it did not address existing discoloration.

Another study used a 5% concentration paired with other actives and focused on allevating brusing [2].

Recommended Phytonadione Products

Watercress contains Vitamin K along with C, E and copper.  One Watercress products we like is Watercress Eye Gel.

Farmaesthetics Watercress Eye Gel

This Farmaesthetics Watercress Eye Gel contains Watercress and certified organic herbs, flowers, and oils from American family farms. An ideal combo to restore, revitalize and refresh.

Vitamin K We love using products with watercress on the delicate eye area skin

Peter Thomas Roth

Peter Thomas Roth POWER K EYE RESCUE combines Phytonadione with several treating ingredients to fix the underlying problem and address existing discoloration.

More UnderEye Dark Circle Options

It is often difficult to conceal dark circles and may be best to keep the skin hydrated and dewy to refract the light.

Another option is brighten around the orbital eye area instead.

Some helpful brightening options we love:

  • YSL Touche Eclat High Cover Concealer
  • Why Chantecaille Eye Shade is the Best Brightener (we love shades Peony and Ginger to lighten and brighten the eye area)

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

June 19, 2019 · 7 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.

Tamanu Oil comes from the nuts of the Tamanu Tree.

ABOUT TAMANU OIL
