Marini SkinSolutions® C-ESTA® Face Serum is an award-winning, best-selling antioxidant serum designed to help firm, lift, brighten, hydrate, and protect the skin while reducing the appearance of fine lines and wrinkles.

The formula combines lipid-soluble Vitamin C (Ascorbyl Palmitate), DMAE, Hyaluronic Acid, Vitamins B5 and E, and additional antioxidants to address multiple visible signs of skin aging while helping defend against oxidative and environmental stress. Marini specifically highlights its lipid-soluble Vitamin C for providing excellent stability and penetration with less irritation than traditional L-ascorbic acid.

DMAE complements Vitamin C by helping skin appear smoother, firmer, more toned, and visibly lifted, while Hyaluronic Acid, Panthenol, Vitamin E, and Urea provide hydration and barrier support. The result is a lightweight daily antioxidant serum that helps promote a brighter, more contoured and youthful-looking complexion.

Marini recommends C-ESTA® Face Serum for fine lines and wrinkles, discoloration, and volume and laxity concerns, and lists it as appropriate for combination, dry, and oily skin types.

DMAE

Dimethyl MEA

DMAE is one of the ingredients that makes C-ESTA® much more than a conventional Vitamin C serum.

Marini incorporates DMAE for its potential firming and toning effects, helping improve the appearance of fine lines, wrinkles, and visible sagging. The brand describes the combination as creating smoother, firmer skin with a more visibly “lifted” appearance.

Benefits:

✔️ Helps improve visible firmness

✔️ Promotes a more lifted appearance

✔️ Helps improve skin tone

✔️ Helps soften visible fine lines

---

Hyaluronic Acid

Sodium Hyaluronate

Hyaluronic Acid helps maintain hydration and plumpness while balancing the serum's corrective and antioxidant technologies.

Marini notes that Sodium Hyaluronate can hold up to 1,000 times its molecular weight in water, helping support moisture balance, elasticity, and barrier function.

Benefits:

✔️ Provides hydration

✔️ Helps improve visible plumpness

✔️ Helps soften dehydration lines

✔️ Supports skin elasticity

✔️ Helps maintain moisture balance

✔️ Supports healthy barrier function

Vitamin B5

Panthenol

Panthenol, the provitamin form of Vitamin B5, provides moisturizing, soothing, and barrier-supportive benefits.

Benefits:

✔️ Helps improve hydration

✔️ Supports healthy barrier function

✔️ Helps calm visible irritation

✔️ Promotes softer-looking skin

✔️ Complements active antioxidant ingredients

---

Vitamin E

Tocopheryl Acetate

Vitamin E is a lipid-soluble antioxidant that works especially well alongside Vitamin C.

It helps defend against oxidative stress while providing additional moisturizing and barrier-supportive benefits.

Benefits:

✔️ Provides antioxidant protection

✔️ Complements Vitamin C

✔️ Supports skin barrier function

✔️ Helps maintain moisture

✔️ Supports healthier-looking skin

---

Ergothioneine

Advanced Antioxidant Amino Acid

Ergothioneine provides another layer of antioxidant defense.

Marini describes Ergothioneine as a powerful antioxidant amino acid that helps scavenge reactive oxygen species and reduce oxidative stress.

Benefits:

✔️ Provides additional antioxidant defense

✔️ Helps protect against oxidative stress

✔️ Supports healthier-looking skin

✔️ Strengthens the serum's overall environmental defense strategy

---

Urea

Urea is naturally found within the skin's Natural Moisturizing Factor and helps support hydration and smoother-looking texture.

Benefits:

✔️ Helps attract moisture

✔️ Supports softer skin

✔️ Helps improve rough texture

✔️ Supports healthy moisture balance

---

Acetyl Tyrosine

Acetyl Tyrosine is an amino-acid derivative included for antioxidant support and its ability to complement other topical ingredients.

Marini also highlights its ability to help improve the appearance of fine lines and wrinkles.

Benefits:

✔️ Provides antioxidant support

✔️ Helps improve visible fine lines

✔️ Complements the serum's corrective ingredients

✔️ Supports overall skin quality

---

Zinc Sulfate

Zinc Sulfate provides antimicrobial, soothing, and skin-supportive properties within the formula. Marini notes that it can be particularly beneficial for blemish-prone skin due to its ability to help reduce bacterial growth and inflammation while supporting healthy skin function.

---

Lift + Firm + Protect

C-ESTA® Face Serum is designed around three primary objectives:

LIFT

DMAE helps improve visible skin tone and creates a smoother, more lifted-looking appearance.

FIRM

Lipid-soluble Vitamin C supports collagen synthesis while the overall antioxidant complex helps improve the appearance of fine lines and wrinkles.

PROTECT

Vitamin C, Vitamin E, Ergothioneine, and other antioxidants help defend skin against free radicals, pollution, and environmental oxidative stress.

That combination is what separates C-ESTA® from a basic brightening Vitamin C serum.

---

Clinical Results

C-ESTA® Face Serum has also been evaluated in an independent published split-face Vitamin C study.

Marini reports statistically superior improvement in skin texture with C-ESTA® Face Serum compared with the Vitamin C alternative evaluated in the study. The manufacturer's current product page also reports that 79% of subjects preferred the feel/application and 82% preferred the smell of C-ESTA® compared with the leading Vitamin C alternative. The study was published in the Journal of Drugs in Dermatology in 2014.

Professional Insight

C-ESTA® Face Serum is one of those products that helps explain why not all Vitamin C serums should be considered interchangeable.

When most people hear “Vitamin C serum,” they immediately think of L-ascorbic acid. It's an excellent ingredient, but it can also be unstable and irritating for certain skin types.

C-ESTA® takes a different approach.

Marini uses Ascorbyl Palmitate, a stable, lipid-soluble form of Vitamin C, which provides antioxidant and collagen-supporting benefits while offering excellent formulation stability and potentially better tolerability than traditional L-ascorbic acid.

But the ingredient that really changes the personality of this serum is DMAE.

Instead of focusing only on antioxidant protection and brightness, C-ESTA® is designed to help create a visibly firmer, smoother and more lifted appearance.

That makes it particularly appealing for clients whose goals aren't limited to discoloration.

If you're beginning to notice fine lines, changes in firmness, laxity, dullness, uneven tone, or a less-defined appearance, C-ESTA® provides a much broader strategy than a conventional brightening serum.

---

Why Lipid-Soluble Vitamin C Matters

The skin barrier is lipid-rich.

Using a lipid-soluble form of Vitamin C gives C-ESTA® a very different formulation profile from traditional water-based L-ascorbic acid serums.

Marini specifically highlights Ascorbyl Palmitate for its stability, penetration, antioxidant activity, collagen support, brightening benefits, and lower irritation potential compared with L-ascorbic acid.

That can make C-ESTA® particularly interesting for clients who say:

“I know I should use Vitamin C, but every Vitamin C serum I've tried irritates my skin.”

It doesn't mean irritation is impossible—every skin is different—but the form of Vitamin C used here offers another approach.

---

More Than Vitamin C

We also like that Marini doesn't rely on Vitamin C alone.

The formula layers multiple complementary ingredients:

Vitamin C → antioxidant defense + collagen support + brightness

DMAE → firmness + tone + lifted appearance

Hyaluronic Acid → hydration + plumpness

Vitamin B5 → hydration + barrier support

Vitamin E → antioxidant + lipid support

Ergothioneine → additional oxidative-stress defense

That makes C-ESTA® a particularly strong daily serum for someone looking for a combination of prevention + correction + hydration rather than one narrowly targeted benefit.

Marini SkinSolutions® C-ESTA® Face Serum is much more than a daily Vitamin C serum. By combining lipid-soluble Vitamin C with DMAE, Hyaluronic Acid, Vitamins B5 and E, Ergothioneine, and additional antioxidants, it simultaneously helps protect against environmental stress while supporting brighter, smoother, firmer, more hydrated and visibly lifted-looking skin.

For clients who want the benefits of Vitamin C but are equally concerned with firmness, fine lines, laxity, texture, and overall skin quality, C-ESTA® is an excellent everyday antioxidant treatment and one of the signature products within the Marini SkinSolutions® collection.
