Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate benefits for your acne and oiliness as peptides like copper tripeptide-1 and hexapeptide-11 can support skin repair and potentially regulate sebum, which is suitable for your oily skin without contributing to excess oiliness.
- The serum provides excellent plumping and firming effects due to multiple peptides such as palmitoyl pentapeptide-4, enhancing overall skin health.
- The safety profile is excellent, with no risks of irritation for your oily skin due to the absence of prohibited or harsh ingredients.
How to apply
- Could be used as part of your PM routine. Start 3 times a week and build up to daily use if your skin tolerates it well.
- Apply your serum after cleansing and toning, but before putting on your moisturizer.
- Gently press 2 to 3 drops of the serum into your skin and let it absorb for a minute.
- Apply the serum on clean, dry skin to help manage your blemishes safely.
- Do a patch test before your first use and avoid the delicate eye area.

Questions and answers
How well does Mary & May 6 Peptide Complex Serum work for oily acne-prone skin?
Mary & May 6 Peptide Complex Serum is a moderate fit for your oily acne-prone skin, as its peptides help support skin repair and firming without causing extra oiliness or irritation. To work best for this skin type, a treatment of this kind needs targeted ingredients like niacinamide, propolis, or Vitamin C to actively control oil and clear breakouts.
Which ingredients make this serum a good fit for oily acne-prone skin?
Copper Tripeptide-1 and Hexapeptide-11 make this serum a good fit by supporting skin repair and helping regulate sebum for oily skin. To work best for oily and acne-prone skin, a treatment of this type needs soothing extracts, oil-controlling ingredients like niacinamide or Vitamin C, and lightweight hydrators.
What does Copper Tripeptide-1 do for oily acne-prone skin?
Copper Tripeptide-1 helps calm oily, acne-prone skin by reducing inflammation and protecting against damage, while also improving overall skin barrier health. This ingredient supports tissue repair and helps smooth out skin texture, making it a useful addition for managing breakouts.
Skin Research and Technology, 2026Journal of Biomaterials Science. Polymer Edition, 2008
What does Hexapeptide-11 do for oily acne-prone skin?
Hexapeptide-11 helps protect skin cells from everyday damage and may improve firmness, but oily acne-prone skin also needs ingredients that control oil and soothe swelling to truly stay clear and smooth.
Where does this serum go in a skincare routine for oily acne-prone skin?
This serum goes in your evening routine after cleansing and toning, and before moisturizing. Oily acne-prone skin needs a treatment of this type to include ingredients that help repair skin and regulate oil without clogging pores.
Can I use this serum with retinol, and in what order?
You can use this serum with retinol, applying the treatment serum after cleansing and toning, and before your moisturizer. It is unlikely to cause irritation due to its gentle formula, but oily acne-prone skin often needs targeted ingredients like salicylic acid or niacinamide to better manage breakouts and excess oil.
How often should I use this serum?
You can use this treatment in the evening as part of your routine. This serum is unlikely to cause irritation for your oily skin, though an oily acne-prone skin type needs a product that also features ingredients to actively clear pores and control breakouts.
Can this serum clog pores, cause breakouts or purging for oily acne-prone skin?
This serum is unlikely to cause breakouts or clog pores on oily acne-prone skin because it has a very safe formula with no harsh or heavy ingredients. However, it only works moderately well for oiliness and acne, so oily acne-prone skin needs a product of this type that also includes lightweight, oil-balancing ingredients and acne-fighting components.
Is this serum fragrance-free and alcohol-free?
Yes, it has no fragrance and no drying alcohol.
