About the Brand
DIME TBT® Serum is manufactured by DIME, a company that claims to focus on creating clean, vegan, and cruelty-free skincare products. It claims its formulas are free from harmful chemicals such as parabens, sulfates, and phthalates.
Based in the USA, DIME claims it is dedicated to producing ethical skincare solutions and ensures safety by using ingredients supported by the Environmental Working Group (EWG).
DIME emphasizes clean beauty while positioning its products as approachable luxury. However, its products are expensive and primarily sold online, which may not be convenient for customers who prefer in-store purchases to properly check the product.
How Does DIME TBT® Serum Work?
DIME TBT® Serum works by combining exfoliating and hydrating ingredients that aim to improve skin texture and combat visible signs of aging. The serum’s key active ingredients (Mandelic acid, Bakuchiol, and Resveratrol) may be able to promote healthier-looking skin.
Mandelic acid, an alpha hydroxy acid (AHA), is known for its ability to reduce fine lines and uneven pigmentation. Niacinamide is popular for soothing and brightening the dark areas of the skin. Bakuchiol also promotes complexion without the irritation often associated with traditional retinoids like retinol.
Also, Resveratrol is a potent antioxidant claimed to protect the skin from free radical damage while smoothing the appearance of fine lines.
While the serum combines these ingredients for anti-aging effects, its results may depend on individual skin types and consistency of use.
DIME TBT® Serum Ingredients: Are They Safe & Effective?
Mandelic Acid
Mandelic acid, an alpha hydroxy acid (AHA), is included in DIME TBT® Serum for its gentle exfoliating properties. It promotes cell turnover, which may help improve uneven skin texture and reduce the appearance of fine lines.
As highlighted in our Allies of Skin Review (another serum that has this ingredient), mandelic acid is also known for being less irritating compared to other AHAs, which makes it suitable for sensitive skin. A study in Molecules shows its potential to improve hyperpigmentation and skin clarity. However, the dose affects its safety.
Sheau-Chung Tang (Department of Biochemistry, School of Medicine, Tzu Chi University) and his colleagues assert in their report, We conclude that whether AHA is a friend or foe of human skin depends on its concentration.
Resveratrol
Resveratrol, a plant-based antioxidant, is included in the serum to help protect the skin from oxidative stress caused by environmental factors like UV radiation and pollution. The Scientific Research Publishing finds that this ingredient may also aid in smoothing fine lines and improving skin firmness.
Our WOWMD Resveratrol Review (another supplement containing this ingredient) mentions how resveratrol protects cellular structures from oxidative damage. This makes it good for antiaging.
Bakuchiol
Bakuchiol is a plant-derived alternative to retinol. It is known to help improve skin texture and reduce the appearance of fine lines. As noted in clinical trial findings published in the British Journal of Dermatology, bakuchiol is comparable with retinol in its ability to reduce premature aging due to UV radiation. But unlike retinol, it is gentle on the skin, making it a suitable option for those with sensitivity.
Niacinamide
Niacinamide, a form of vitamin B3, is known for its ability to improve skin barrier function and reduce redness. DIME TBT® Serum may help soothe irritated skin while enhancing hydration and brightening dull areas. A study in the International Journal of Cosmetic Science shows niacinamide’s role in reducing fine lines and evening out skin tone.
How to Use DIME TBT® Serum?
To use DIME TBT® Serum effectively:
- Cleanse your face and neck with a gentle cleanser.
- Apply 3–5 drops of the serum to the face and neck.
- Gently massage the product into the skin until fully absorbed.
- Use the serum both in the morning and at night as part of your skincare routine.
- Follow up with a moisturizer to lock in hydration and sunscreen during the day to protect your skin.

Side Effects of DIME TBT® Serum
DIME TBT® Serum is marketed as safe for most skin types due to its clean and vegan formula. However, some individuals may experience minor side effects, such as:
- Irritation or redness, especially on sensitive or compromised skin.
- Dryness or peeling during the initial use due to the exfoliating properties of mandelic acid.

DIME TBT® Serum is marketed as safe for external use due to its clean and vegan formula. The product is free from parabens, sulfates, and phthalates, which may reduce the likelihood of adverse reactions for most users.
However, individuals with sensitive skin or allergies to certain ingredients, such as mandelic acid or plant extracts, may experience mild irritation. The product is intended for external use only and should not be applied to broken or irritated skin.
Pregnant or nursing individuals, as well as those with known sensitivities, should consult a dermatologist or healthcare provider before use.

For example, Lucylu wrote, I’m 50 years old and love this product. It keeps my skin hydrated and dewy-looking!

DIME TBT® Serum Review: Conclusion
DIME TBT® Serum claims to improve skin texture, reduce visible signs of aging, and promote a brighter complexion with its clean and vegan formula. Its inclusion of mandelic acid, bakuchiol, and resveratrol offers promising anti-aging benefits, and the brand’s commitment to ethical skincare practices may appeal to conscious consumers.
However, customer reviews are mixed, with some users praising its hydrating effects while others reported irritation or dissatisfaction with the product’s scent. Also, the serum is relatively expensive, and since it comes in a small 30 mL bottle, users will have to buy it frequently. These costs add up.
That said, while DIME TBT® Serum may work well for some, its inconsistent results and high price suggest it might not be the ideal solution for everyone.
As we age the composition, texture and appearance of our skin changes. Signs of skin aging include wrinkles, fine lines, loss of moisture, uneven tone and dull, tired-looking skin. There are countless anti-wrinkle creams on the market promising to make skin look and feel younger. Many anti-wrinkle creams promise everything short of a facelift or to provide the much sought after "fountain of youth". In reality most are just moisturizers marketed as anti-aging products.
Below you'll find some of the most effective wrinkle serum/cream formulations on the market today, in our opinion.
