([Journal of Cosmetic Dermatology, 2022](https://pubmed.ncbi.nlm.nih.gov/34910367/)) ## Why other serums fit combination skin better - Niacinamide and ferulic acid incorporated in a stable multiple emulsion successfully reduced melanin, sebum, and skin erythema while improving skin elasticity and hydration in human skin compared to a placebo. ([BioMed Research International, 2022](https://pubmed.ncbi.nlm.nih.gov/35342760/)) - A panthenol-enriched mask improved skin hydration, regulated sebum, and reduced redness and TEWL across dry sensitive, oily sensitive, and oily acne skin subgroups with excellent tolerance and no adverse reactions.

While highly praised for its potent antioxidant benefits and ability to smooth skin texture, some users with sensitive skin experience stinging or find the texture slightly sticky before it fully absorbs. - Liked: Brightens skin tone (mostly mentioned) - Liked: Fades dark spots (often mentioned) - Disliked: High price (often mentioned) - Liked: Fast absorption (sometimes noted) - Liked: Improves texture (sometimes noted) - Disliked: Oxidizes quickly (sometimes noted) - Disliked: Sticky consistency (sometimes noted) - Liked: Reduces fine lines (rarely noted) - Disliked: Packaging issues (rarely noted) - Disliked: Skin irritation (rarely noted) ## How to apply - Use your serum as part of your PM routine.

Obagi Vitamin C Serum is a weak match for combination skin because it does not directly address oily shine or provide the specific hydration balance your skin needs. A treatment for this skin needs ingredients like niacinamide, propolis, and zinc PCA to regulate oiliness and offer optimal hydration without causing excess oiliness or dryness. Sources: [Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/32052907/) ### Which ingredients make this serum a poor fit for combination skin?

A treatment for combination skin needs ingredients like niacinamide, propolis, or zinc PCA to regulate oiliness and provide balanced hydration. ### What does Vitamin C do for combination skin? Vitamin C helps brighten dull areas and smooth out uneven texture on combination skin while protecting against daily environmental stress. It may also help keep pores clear and skin firm by supporting collagen production, though drier spots may need an added moisturizer to stay comfortable. Sources: [Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31975502/) ### What do Essential Oils do for combination skin? Essential oils may help calm irritation and keep skin clear thanks to their natural antimicrobial and anti-inflammatory properties. However, because some types can be too strong, combination skin generally needs lightweight, soothing formulas that balance oil without causing dryness. Sources: [Acta Microbiologica Et Immunologica Hungarica, 2010](https://pubmed.ncbi.nlm.nih.gov/20350876/), [Frontiers in Pharmacology, 2021](https://pubmed.ncbi.nlm.nih.gov/34707494/) ### Where does this serum go in a skincare routine for combination skin?

Combination skin needs a product of this type that also manages excess oil and provides a balanced level of hydration. ### Can I use this serum with retinol, and in what order? You can use this serum in your morning routine and retinol at night to keep your skin safe, since combining them at the same time may cause irritation. Combination skin needs products that manage oily shine and provide the right hydration balance with lightweight ingredients. ### How often should I use this serum? This serum is used in the evening once a week to start, and people who tolerate it well and see good results can carefully use it more often. Combination skin needs a product of this type to include ingredients that help manage excess oil and provide a balanced level of hydration. ### Can this serum clog pores, cause breakouts or purging for combination skin? This serum is unlikely to clog pores or cause breakouts on combination skin because its formula is safe and free of harsh irritants.
