Lovi Assistant explains

  • Suitable for normal skin, this serum contains Palmitoyl Hexapeptide-19 and Niacinamide to stimulate collagen and repair the skin barrier, offering general hydration and soothing benefits that are supportive but not primary for your redness and irritation concerns.
  • The presence of Dipotassium Glycyrrhizate further aids in soothing, though its impact on significant redness and irritation may be limited.
  • The product is safe for your sensitive skin, with no harsh ingredients or risks of irritation.

How to apply

  • Use your serum in the PM routine, starting 3 times a week before building up to daily use if your skin is happy.
  • Apply the serum after cleansing and toning, but before putting on your moisturizer for the best results.
  • Gently press 2-3 drops of the serum into your skin and wait a minute ⏱ for it to soak in.
  • Since your skin is sensitive and easily irritated, apply the serum on completely dry skin to help keep it calm.
  • Always do a patch test before your first use and avoid getting the serum too close to your eyes .

Questions and answers

How well does DIME Super Firm Serum work for sensitive skin?

This serum works for sensitive skin, but other products fit it better because its soothing ingredients only offer supportive benefits for your redness and irritation. A product of this type needs potent antioxidants, hydrating components, and skin-repairing ingredients to properly care for sensitive skin.

Journal of the European Academy of Dermatology and Venereology, 2016

Which ingredients make this serum a good fit for sensitive skin?

Niacinamide, acetyl dipeptide-1 cetyl ester, and dipotassium glycyrrhizate help soothe and support sensitive skin. A product of this type needs calming antioxidants, barrier-repairing ingredients, and soothing agents specifically targeted to address significant redness and irritation.

Journal of the European Academy of Dermatology and Venereology, 2016

What does Niacinamide do for sensitive skin?

Niacinamide helps calm sensitive skin by strengthening the skin barrier and reducing redness and irritation. It is very well tolerated and may improve overall comfort and resilience with regular use.

Cutis, 2005Journal of Cosmetic Dermatology, 2004

What does Palmitoyl Hexapeptide-19 do for sensitive skin?

Palmitoyl Hexapeptide-19 is unlikely to irritate sensitive skin, but products of this type for sensitive skin need soothing ingredients and gentle formulas that help calm redness and support the skin barrier.

Pharmaceuticals, 2021

Where does this serum go in a skincare routine for sensitive skin?

This treatment serum goes in the evening routine after your soothing toner and before your moisturizer. Putting it in the evening helps keep your routine simple and adds extra safety around sun exposure.

Can I use this serum with retinol, and in what order?

You can use this serum with retinol by applying it at night after your cleanser and soothing toner, and before your moisturizer. It is safe for sensitive skin and unlikely to cause irritation, though a product for this skin needs extra calming and barrier-repairing ingredients to fully target redness and stinging.

Journal of Cosmetic Dermatology, 2024Journal of the European Academy of Dermatology and Venereology, 2016

How often should I use this serum?

You can use this treatment in the evening as part of your routine. It is safe for sensitive skin and is unlikely to cause irritation.

Can this serum clog pores, cause breakouts or purging for sensitive skin?

DIME Super Firm Serum is unlikely to clog pores or cause breakouts for sensitive skin, as it has a safe profile with no harsh ingredients. However, to truly calm redness and irritation, sensitive skin needs gentle, targeted soothing ingredients and barrier-repairing elements that offer stronger relief.

Is this serum fragrance-free and alcohol-free?

Yes, it has no fragrance and no drying alcohol.
