Overview Of Tatcha The Dewy Serum

Having a dewy skin is the top-tier goal of every skincare routine. Dewy skin looks healthy, and moisturized, and has a natural glow to it. Previously, a matte look was all the hype and dewy skin was considered less desirable as it looked oily. In the early 2000’s however, South Korea’s makeup industry revolutionized the dewy skin trend known as “Chok Chok” (meaning moist and glowy finish).

TL;DR

  • Over 60% of adults in the U.S. report dealing with dull or dehydrated skin due to environmental stressors and aging.
  • According to research published in the Dermatol Ther., hyaluronic acid improves skin hydration and elasticity.
  • Tatcha The Dewy Serum may help replenish moisture, plump the skin, and restore radiance using clean, plant-derived ingredients proven to enhance hydration and texture.

Tatcha The Dewy Serum promises to deliver these results with as few steps as possible. In this comprehensive review, we take a closer look at this serum, its ingredients, and whether it is worth a try or not. Join us in this exploration as we uncover all the details regarding this product.

What Is Tatcha The Dewy Serum?

Tatcha The Dewy Serum is a lightweight serum that features clean and gentle ingredients to moisturize, plump, and smooth the skin for a dewy finish. The formula contains plant-based hyaluronic acid, lactic acid in hadasei-3 (AHAs), as well as sugarcane-derived squalene. It is suitable for all skin types and targets dullness, dehydration, and fine lines and wrinkles.

Its texture while light, is not overly runny and is claimed to be just the right balance between light and thick, somewhat like a gel. Its appearance is milky and may absorb quickly when applied to the skin, but may still leave the skin feeling soft and hydrated. As for smell, this serum does not have any noticeable fragrance which is a plus for users who are sensitive to strong smells.

This serum is packed in a lightweight plastic bottle that is Tatcha’s classic lavender color. Thanks to this lightweight packaging, this serum is suitable for travel and use on the go. In addition to that, the bottle has a pump to dispense The Dewy Serum, making it easy to control the amount you want to use. Tatcha The Dewy Serum perfectly pairs with Tatcha The Dewy Skin Cream another product in the collection.

Who Is The Manufacturer Of Tatcha The Dewy Serum?

Tatcha was founded by Vicky Tsai after a visit to Kyoto where she encountered a culture that healed her acute dermatitis. She studied the Japanese ingredients that helped transform her skin and with that, Tatcha was born. The company is not a solo venture as it is supported by a team of scientists, geisha, and cultural advisors who help in the crafting of the formulas.

Every Tatcha formula is created at the Tatcha Institute in Tokyo by leading scientists who innovate within the confines of tradition. At the core of Tatcha products lies the balance between timeless Japanese botanicals and clinical ingredients with scientific backing.
According to the company, Tatcha products are well-being rituals as they not only improve skin health, but also physical, mental, and emotional wellbeing.

How Does Tatcha The Dewy Serum Work?

Tatcha The Dewy Serum works to moisturize the skin through its three main ingredients; lactic acid, hyaluronic acid, and sugarcane-derived squalene.

Lactic acid in this serum is derived from three Japanese superfoods including Akita rice, Okinawa algae, and Uji green tea. As a chemical exfoliant, lactic acid has the ability to improve the skin’s appearance. Other than that, it keeps the skin naturally hydrated[1].

As for hyaluronic acid, also known as hyaluronate or hyaluronan, is a super ingredient in the world of skincare. It has water retention capabilities like no other. For instance, a quarter teaspoon of this ingredient can hold up to one and a half gallons of water. So, for this reason, it keeps the skin hydrated, flexible, and wrinkle-free.

Lastly, this serum contains sugarcane-derived squalene which is a humectant that locks in moisture, keeping the skin hydrated all day long. When applied to the skin, squalene enhances skin hydration, reduces moisture loss, and prevents the skin from drying out. The best thing about squalene is that while it is an oil, it is non-comedogenic which is to say it does not clog pores.

Tatcha The Dewy Serum Ingredients – Are they Safe And Effective?

Some of the front-line ingredients in this serum include;

Uji Green Tea

Uji green tea is a type of green tea grown in Uji, Kyoto in Japan. A 2016 review study in the Antioxidants journal found that green tea polyphenols in topical formulations may be beneficial in reducing sebum secretion and in acne treatment[2].

According to researchers Eunji Kim and team, established that green tea contains amino acids, proteins, and lipids which are essential for enhancing skin hydration. Epigallocatechin (EGCG), an abundant polyphenol in green tea was declared to have

positive effects on skin hydration, moisture retention, and wrinkle formation[3].

Okinawa Algae

Okinawa algae is a red alga. It is considered a super ingredient in bathing products, hair products, skincare, and healthy diets. In a review study published in the International Journal of Pharmacy, red algae were discovered to have numerous compounds with therapeutic properties. Red algae’s major applications are anti-wrinkling and skin whitening[4].

Researcher Yoon-Yen Yow, Department of Biological Sciences, School of Science & Technology, Sunway University, Malaysia agrees that

marine algae are rich in bioactive substances that have shown to exhibit strong benefits to the skin, particularly in overcoming rashes, pigmentation, aging, and cancer[5].

Akita Rice

Rice grown in Akita Japan is claimed to have skin care benefits which could be true as rice has been used for cosmetic purposes for centuries. According to studies in the Journal of Cosmetic Dermatology, phenolic compounds of rice such as betaine, rice bran, squalene, and tricin have been to have antiaging, anti-inflammatory, whitening, moisturizing, and photo-protective properties[6].

Researcher Ivana Binic and her team from the Clinic of Dermatovenereology, Clinical Center of Nis, Serbia, demonstrated that fermented rice water (rice wine) can help improve skin damage from the sun. By increasing collagen in the skin, it helps keep the skin supple and prevent wrinkling. Rice wine also has natural sunscreen properties[7].

Hyaluronic Acid

Hyaluronic acid occurs naturally in the eyes and joints. It works to cushion and lubricate the joints as well as other tissues in the body. In skincare, hyaluronic acid is used particularly for its hydrating and anti-aging properties as per studies in the Dermatologic Therapy journal[8]. Researcher Anca Maria Juncan and colleagues published the advantages of hyaluronic acid in the Molecules journal[9]. According to them

HA has a multitude of applications based on specific properties such as high hygroscopicity, viscoelastic nature, biocompatibility, and non-immunogenicity.

Additionally, Hyaluronic Acid’s hydration effects on the skin may optimize the absorption of other active ingredients. Considering these benefits, it is used in skincare products like Allies Of Skin, which help to attract and retain moisture, keeping the skin plump and hydrated.

Sugarcane Derived Squalene

Squalene, a triterpene compound, can be found in many plant and fish sources. It is important in skincare owing to its many benefits including hydrating, reducing visible signs of aging, and non-comedogenic properties. A 2018 review study published in the Molecular Nutrition and Food Research journal provided that squalene has antioxidant, anti-inflammatory, and anti-atherosclerotic properties[10].

According to researchers Se-Kwon Kim and Fatih Karadeniz,

several studies exhibited results that prove certain bioactivities for squalene. Up to date, anticancer, antioxidant, drug carrier, detoxifier, skin hydrating, and emollient activities of these substances have been reported both in animal models and in vitro environments[11].

How To Use Tatcha The Dewy Serum?

To achieve a radiant, hydrated glow, apply 1-2 pumps of The Dewy Serum to clean, dry skin. Gently massage the serum onto your face and neck using upward, circular motions to ensure even absorption. For best results, incorporate it into your daily skincare routine, both morning and evening.

Follow with a moisturizer, such as The Dewy Skin Cream, to lock in hydration and enhance the serum’s benefits. Avoid contact with eyes, and if irritation occurs, discontinue use. Consistent use will maximize its hydrating, smoothing, and plumping effects, leaving your skin looking dewy and refreshed.

Benefits Of Tatcha The Dewy Serum

May restore and replenish the skin – Over time, the skin loses its glow and health due to elements such as sun exposure and pollutants in the environment. The Dewy Serum’s proprietary complex Hadasei-3 may help replenish the skin.

May hydrate and plump the skin – The hydrating prowess of hyaluronic acid is unmatched. In this formula, hyaluronic acid may moisturize and plump the skin for a fresher, rejuvenated, and youthful look.

May lock in moisture – Once hyaluronic acid hydrates the skin, squalene jumps in with its moisture-locking capabilities, leaving skin hydrated for longer.

Side Effects Of Tatcha The Dewy Serum

The Dewy Serum is dermatologist-tested and formulated to be gentle on all skin types. However, some users may experience minor side effects, such as slight redness, tingling, or irritation, particularly if they have sensitive skin or are new to active ingredients like hyaluronic acid. These effects are typically temporary and subside as your skin adjusts. To minimize the risk, perform a patch test before full application.

Avoid using on broken or irritated skin. If persistent irritation occurs, discontinue use and consult a dermatologist. Overall, side effects are rare, and most users enjoy its hydrating and smoothing benefits without issue.

Safety Of Tatcha The Dewy Serum

The Dewy Serum is crafted with safety and efficacy in mind. It is dermatologist-tested, non-comedogenic, and free from harsh ingredients like mineral oil, synthetic fragrances, sulfates, parabens, and phthalates. Its gentle formula is suitable for all skin types, including sensitive skin.

What Do Tatcha The Dewy Serum Reviews Say?

I had high hopes for The Dewy Serum, but I didn’t notice much of a difference in my skin after a few weeks of use. For the price, I expected better results. –Alex M.

The serum feels nice on the skin, but it didn’t live up to the hydration claims for me. My skin still felt dry by the end of the day. –Jordan T.

It’s okay, but not worth the hype. The texture is pleasant, but I didn’t see any significant improvement in my skin’s elasticity or glow. –Taylor R.

While the packaging is beautiful, the product itself didn’t work for me. It caused slight irritation, and I had to stop using it after a few days. –Morgan L.

I wanted to love this serum, but it’s just too expensive for the minimal results I experienced. There are more affordable options that work better for me. –Casey P.

Tatcha The Dewy Serum Review – Conclusion

Tatcha’s The Dewy Serum is a great addition to your skincare routine especially if you are already a fan of The Dewy Cream. However, the price tag is quite high with this one. At a whopping $89.00, it can be too expensive to use in the long run.

Although it features exemplary ingredients, this serum is not as non-comedogenic as advertised. Multiple reviewers complained of breakouts, meaning the serum can clog pores. It also has a mild fragrance that could not work well for those with smell sensitivities. Bearing all these in mind, you can find better serums in the market.

However, if you are feeling adventurous, have normal skin, and want to splurge a bit, then The Dewy Serum is a product you should definitely add to your dresser.

  1. Maris Calder




    Lightweight feel but results take too long
    This serum feels light and absorbs pretty quickly, which made it easy to use daily. I did notice a little boost in hydration over time, but nothing dramatic. The bigger issue is how long it takes to see any real changes. My skin still looked a bit dull after weeks of use. For the cost, I expected faster or more noticeable results, but it felt kinda slow overall.
  2. Liora Fenn




    The dewy serum all show, no glow
    Gave this a shot over 10 weeks, applyin’ 1-2 pumps daily after cleansin’, followin’ with my usual cream. The plant-based hyaluronic acid helped with basic hydratation, makin’ skin less dull thanks to the green tea and algae, and it’s non-comedogenic so no breakouts. Love it’s clean, no-synthetic-fragrance vibe and cruelty-free status from the Tokyo institute. Drawbacks? Super expensive at $89 a pop, and that mini size is useless for long-term. Saw minor tinglin’ early on, and the dewy effect was lackluster more like alright than wow. The 60-day guarantee saved me from feelin’ totally ripped off. Not bad, but expectin’ more bang for the buck.
