Page built Nov 8, 2026How the Fit score works

Lovi Assistant explains

  • Offers moderate moisturizing for your normal skin due to the presence of glycerin and sodium hyaluronate, which provide hydration but lack sufficient emollient ingredients like ceramides for optimal nourishment.
  • The formula includes soothing ingredients like licorice root extract and chamomile extract, offering general skincare benefits that are supportive but not specialized for addressing your main goal of wrinkles and fine lines.
  • The safety profile is excellent, with no risks of irritation for your normal skin due to the absence of prohibited or harsh ingredients.

How to apply

  • Use your moisturizer twice a day in your AM and PM routines. Apply it daily to help smooth fine lines.
  • Apply this product after your toner and serum, but before your SPF in the morning. Follow your cleanser and toner steps to keep your skin balanced.
  • Gently press a small amount into your face and neck. Avoid rubbing the skin too harshly to prevent extra tension.
  • Apply the moisturizer on slightly damp skin to help lock in extra moisture. Clean skin helps the product absorb much more evenly.
  • Avoid the sensitive eye area during application. Do a quick patch test before your very first use to stay safe.

Questions and answers

How well does SU:M37 Secret Essence work for mature skin?

SU:M37 Secret Essence works as an average fit for mature skin, offering moderate hydration through ingredients like sodium hyaluronate and glycerin, while containing soothing extracts like licorice root and chamomile. It has an excellent safety profile with no irritation risks, but it lacks specialized anti-wrinkle actives and richer nourishing ingredients like ceramides to properly smooth fine lines on mature skin.

Clinical, Cosmetic and Investigational Dermatology, 2017

Which ingredients make this essence a good fit for mature skin?

Niacinamide, licorice root extract, centella asiatica extract, and sodium hyaluronate help support mature skin by providing hydration and soothing benefits. To best fit this skin type, a product of this type needs specialized anti-wrinkle actives and rich nourishing ingredients like ceramides.

Clinical, Cosmetic and Investigational Dermatology, 2017Dermatologic Therapy, 2022

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.

Antioxidants, 2021Journal of Cosmetic Dermatology, 2004

What does Licorice Root Extract do for mature skin?

Licorice Root Extract helps calm mature skin and may reduce dark spots and redness. It contains antioxidants that protect skin from daily stress and support a more even, bright, and smooth look.

Experimental Dermatology, 2015Journal of Cosmetic Dermatology, 2020

Where does this essence go in a skincare routine for mature skin?

This moisturizing treatment goes in the evening routine after cleansing and before moisturizing, though it can also be used in the morning or twice a day. A product of this type works for mature skin when it includes rich nourishing ingredients like ceramides to smooth fine lines and wrinkles.

Can I use it with retinol, and in what order?

You can use this moisturizing treatment with retinol by applying it before your retinol step to help support your skin barrier and reduce dryness. This product of this type needs nourishing ingredients like ceramides and specialized firming components to better smooth mature skin and target fine lines.

Cutis, 2006

How often should I use this essence?

You can use this treatment in your evening routine, as this time of day provides simplicity and extra safety around sun exposure. To properly care for mature skin, a product of this type needs richer softening ingredients like ceramides to lock in moisture and specialized active ingredients that specifically target fine lines and wrinkles.

Can it clog pores, cause breakouts or purging for mature skin?

This moisturizing treatment is unlikely to cause breakouts or clogged pores for mature skin, as it has an excellent safety profile without harsh ingredients. However, it may cause sensitivity for those prone to adverse reactions from fermented ingredients.

Can I use this essence around the eyes or on my body?

You can safely use this moisturizing treatment around the eyes or on your body because it has an excellent safety profile with no harsh ingredients. However, a product for mature skin needs specialized anti-aging ingredients like potent plant extracts or targeted peptides to properly smooth fine lines and wrinkles in delicate areas.

Surgical and Radiologic Anatomy, 2002

Is it fragrance-free and alcohol-free?

Yes, it has no fragrance and no drying alcohol. Cetearyl alcohol is a fatty alcohol, which soften the skin.
