Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate exfoliation for your normal skin due to mandelic acid, which chemically exfoliates and smooths texture, while sodium hyaluronate and niacinamide provide hydration and barrier support.
- While the formula is generally safe and suitable for normal skin, it lacks specialized ingredients like retinoids or potent antioxidants to effectively target your wrinkles and fine lines.
- The product is safe for your normal skin, with no risks of irritation due to the absence of harsh ingredients and the presence of soothing components like niacinamide and Camellia Sinensis Extract.
How to apply
- Use this exfoliant product in your PM routine once a week to start, increasing frequency only if your skin tolerates it well. Always apply SPF the next morning to protect your skin.
- Apply this exfoliant product after cleansing and toner, but before your moisturizer. This ensures the best absorption into your skin.
- Gently press 2-3 drops of the exfoliant product into your face, avoiding any rubbing. Let it absorb for a minute before moving to the next step.
- Apply this exfoliant product on completely dry skin to get the best results. This helps your normal skin accept the product smoothly.
- Avoid the sensitive eye area while using this exfoliant product. Do a patch test before your first use and avoid mixing it with strong acids.

Questions and answers
How well does DIME TBT Serum work for mature skin?
DIME TBT Serum works for mature skin by providing moderate exfoliation and smoothing texture, though it lacks specialized ingredients to effectively target wrinkles and fine lines. An exfoliant treatment for mature skin needs to be exceptionally safe, target wrinkles with high-quality anti-aging ingredients, and contain potent antioxidants and skin-repairing components to deliver optimal results.
Scientific Reports, 2024Journal of Cosmetic Dermatology, 2021
Which ingredients make this serum a good fit for mature skin?
This serum fits mature skin reasonably well thanks to mandelic acid, which smooths texture, alongside sodium hyaluronate and niacinamide for hydration and barrier support. To properly target wrinkles and fine lines, a product of this type needs strong retinoids or potent antioxidants.
Scientific Reports, 2024Journal of Cosmetic Dermatology, 2021
What does Mandelic Acid do for mature skin?
Mandelic acid helps make mature skin firmer and smoother while improving elasticity and reducing the look of fine lines and uneven tone. It is typically very well tolerated and may improve overall texture and hydration in dry or fragile skin over a few weeks of regular use.
Facial Plastic Surgery, 2018Journal of Drugs in Dermatology, 2025
What does Niacinamide do for mature skin?
Niacinamide helps mature skin by smoothing out fine lines and wrinkles, reducing dark spots, and improving overall skin elasticity. It is also very well tolerated and supports a strong skin barrier to keep skin looking healthy.
Where does it go in a skincare routine for mature skin?
This exfoliant treatment goes in the evening routine, starting at once a week so your skin can adjust safely. Mature skin needs powerful anti-aging ingredients like retinoids and strong antioxidants to effectively target wrinkles and fine lines.
Can I use this serum with retinol, and in what order?
You can use this serum with retinol, but since this product offers moderate exfoliation and lacks strong wrinkle-fighting ingredients, mature skin needs a routine that includes retinoids or potent antioxidants to better target fine lines.
How often should I use it?
Start using this exfoliant treatment once a week in your evening routine, and if your skin tolerates it well and shows good results, you may carefully use it more often. This frequency helps smooth your texture safely while avoiding irritation.
Can this serum clog pores, cause breakouts or purging for mature skin?
This serum is unlikely to clog pores or cause breakouts on mature skin, as it contains gentle exfoliating mandelic acid and soothing ingredients like niacinamide. However, because it includes mandelic acid to speed up skin renewal, some initial purging may happen as it clears out your pores.
Is it fragrance-free and alcohol-free?
Yes, it has no fragrance and no drying alcohol.
