The Acid Chronicles: Lactic Acid!

 

Lactic Acid 1

Happy Tuesday readers!  Hoping your weekend was great!

Awhile ago, I posted on alpha hydroxy acids, otherwise known as AHAs and why they are important in skincare. (In case you missed it or need a refresher, click here)  Lactic acid was one of the AHAs mentioned and here’s why this ingredient is great.

Who: Lactic acid

What skin conditions can it help: Aging and hyperpigmentation

Where it comes from: Derived from milk/sugar

Why it’s important: Lactic acid functions as a humectant, which attracts water and hydrates the skin.   It breaks down the bonds between cells that allow for easier exfoliation of the skin, reducing the appearance of wrinkles.   It also reduces hyperpigmentation due to its ability to suppress the formation of tyrosinase ( the enzyme involved in melanin production).  Because its molecular structure is bigger than glycolic acid, it’s an ideal ingredient to use for those who have sensitive skin because it permeates into the skin slowly, reducing the chances of irritation and inflammation.

How it’s used: Lactic acid can be found in skincare products (i.e. cleansers, toners, moisturizers, serums) and also in professional treatments like chemical peels.  *Like any other exfoliating agent, limit use to a few times per week, wear sunscreen and use caution when using ingredients containing retinol as this can irritate skin.

If you follow my Instagram, you’ll recognize the picture below when I took the Cosmetic Chemistry course at UCLA.  The vial on the right-hand side is what natural lactic acid looks like.

I recently joined Twitter (@stephieestie) so feel free to follow me on there too! I’m still learning how to use it, FYI, but I’m sure I’ll get it in no time. 🙂

Thanks for reading,

Skin Tip: Why You Need to Stay Hydrated

As temperatures drop, you might notice changes in your skin.  Skin can become dry, tight, flaky and perhaps feel more sensitive/irritated. One crucial part of skincare is to keep your skin hydrated because this helps protect us from pathogens, irritation, and from the skin drying out.  If you find that even when you use your moisturizer, your skin still feels dry or tight, us the tips below as a guideline.

Dry Skin/Normal/Dry and Sensitive:  Switch to a heavier cream

Oily/Combination/Sensitive and Oily: Use a hydrating serum/booster underneath your current moisturizer to obtain hydration without heaviness that can lead to breakouts.

As always, if you have any questions, I am here to help. 🙂

Stay warm and hydrated,

SPF Lip Product Guide!

While we may protect ourselves with sunscreen from face to toe, what about our lips?  Many of us forget about protecting our lips from the sun’s damaging rays, so I created a list of  great lip products with SPF.  From things you can find at your local drugstore or nearest Target to Sephora, perhaps you will see your favorites featured here or discover a new favorite one!

EOS

target.com; $2.99

EOS Lemon Drop SPF 15    $2.99 target.com

Summer definitely conjures up images of pitchers filled with ice cold lemonade, making this a fitting product for summer.  Housed in a spherical container, this lip balm contains vitamin E, shea butter and jojoba oil to help keep lips smooth with a hint of lemon.

FSCoral

sephora.com, $22.50

Fresh Sugar Lip Treatment SPF 15 (Coral)  $22.50

I am a fan of Fresh Sugar Lip Treatment because of its hydrating, long-lasting nature that also provides a hint of tint.  Coral is my choice for a fun summer color but there are other shades to suit your likes ranging from nudes, pinks, reds and plums.  The one deterrent is the price so for me, it’s definitely a splurge item.

JBLip

sephora.com, $7.50

Jack Black Intense Therapy Lip Balm SPF 25

Although this product is targeted for men, either gender can use and benefit from this lip balm.  It’s moisturizing without feeling overly heavy and absorbs fairly quickly, leaving lips soft without much shine.

target.com, $1.99

Soft Lips Raspberry 

I used to carry these with me all the time and forgot how much I loved them.  True to the name, they keep your lips soft, and with a delicious raspberry scent and green tea extract, not to mention the great price point, you can keep them both or gift one to someone else.  Unlike other lip balms, these are encased in a slender tube, making them less bulky and space efficient.

baby lips

target.com, $2.99

 

Maybelline Baby Lips Moisturizing Lip Balm SPF 20

Although these are not my absolute favorites, I do like them.  They do soften lips (albeit they don’t last long on me) and although the color range isn’t as expansive as the Fresh Sugar Lip Treatments, the price definitely allows for multiple purchases.

Vintage Sister Lip Balm Review!

Browsing online for lip balms one day, I happened to stumble upon Vintage Sister and I am so glad I did. These lip balms are super moisturizing, non-sticky, and don’t have a waxy feel like other lip balms I have tried.  Bonus: the packaging is super cute, they have fun flavors inspired by seasons, cocktails, and chocolate to name a few, and they are very affordable!

The lip balms are packaged in two forms: tins or tubes.  I purchased both.

Vintage Sister 2

Pros of lip balms in tins:

Very hydrating with ingredients like shea butter and vitamin E

Non-sticky

A unique array of flavors

About $3.95 each

Aromatic without being overwhelming

Cons of lip balms in tins:

Not travel friendly- the lid can slide open easily in bags, pockets, or travel gear and they liquefy quickly when exposed to heat

Unless you use a clean finger or disposable applicator, cross contaminating can occur

Vintage Sister 1

Pros of lip balms in tubes:

Formulated with great moisturizing ingredients such as shea butter and apricot kern oil

Travel friendly

Hygienic

Between $3.50-$4.00 each

Cons of lip balms in tubes:

Limited flavor selection

Although they provide great moisture than most other lip balms, these feel slightly less hydrating than the ones in tins

Overall: I really do love these.  I carry the tube lip balms in my purse and leave the tin lip balms on my bedside table to use at night.  They make adorable gifts, are a fun and inexpensive indulgence, and wear well under lipstick/lipgloss.

A definite repurchase!
