Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Highly suitable for your combination skin due to the presence of multiple peptides like Copper Tripeptide-1 and Hexapeptide-11, which support collagen synthesis and skin repair, offering moderate plumping and firming benefits.
- While the serum provides general skincare benefits like hydration and soothing, it lacks targeted ingredients to address your oily shine.
- The formula is safe for your combination skin, with no risks of irritation due to the absence of prohibited or harsh ingredients.
How to apply
- Use your serum as part of your PM routine. Start using it 3 times a week and move to daily use if your skin likes it.
- Apply the serum after cleansing and toner, and right before your moisturizer.
- Gently press 2-3 drops of the serum into your skin and wait a minute ⏳for it to soak in.
- Apply the serum on clean and dry skin since your skin is not sensitive.
- Always do a patch test before using the serum for the first time, and avoid the eye area .

Questions and answers
How well does Mary & May 6 Peptide Complex Serum work for combination skin?
Mary & May 6 Peptide Complex Serum works well enough for your combination skin by giving you light hydration and firming benefits with its mix of peptides, though it lacks ingredients to manage your oily shine. A treatment for combination skin needs balancing ingredients like niacinamide and zinc PCA to control excess oil while keeping your skin hydrated and smooth.
Which ingredients make this serum a good fit for combination skin?
This serum fits combination skin well through helpful peptides like Copper Tripeptide-1 and Hexapeptide-11, which support collagen and skin repair to give you moderate firming. However, a treatment of this type needs ingredients like niacinamide and zinc PCA to properly manage oily shine.
What does Copper Tripeptide-1 do for combination skin?
Copper Tripeptide-1 helps calm combination skin, smooth fine lines, and support a strong skin barrier. It protects against sun damage and helps tighten the skin, keeping it looking firm and healthy.
Skin Research and Technology, 2026BioMed Research International, 2015
What does Hexapeptide-11 do for combination skin?
Hexapeptide-11 helps improve skin elasticity and protects your skin against oxidative stress. For a good fit on combination skin, this type of product needs hydrating ingredients that balance oily and dry areas without clogging pores.
Where does this serum go in a skincare routine for combination skin?
This treatment serum goes in your evening routine after cleansing and toning, and before moisturizing. Combination skin of this type also needs targeted ingredients to control oily shine.
Can I use it with retinol, and in what order?
You can use this treatment with retinol by applying the retinol first and following with this serum, or by using them on alternating nights to keep your skin calm. The formula is safe for your combination skin, with no risks of irritation due to the absence of prohibited or harsh ingredients.
How often should I use this serum?
You can use this serum in your evening routine, applying it carefully as a treatment step. To properly care for combination skin, this type of product also needs ingredients that balance oily shine.
Can it clog pores, cause breakouts or purging for combination skin?
This serum is unlikely to clog pores or cause breakouts for combination skin because its gentle formula is safe and free of harsh ingredients. However, it lacks targeted ingredients to control oily shine, so this skin type also needs oil-balancing ingredients and lightweight hydrators.
Is this serum fragrance-free and alcohol-free?
Yes, it has no fragrance and no drying alcohol.
