FAQ

Q: Can I use this kit if I have sensitive skin that's also oily?

A: Whilst the Silymarin CF is specifically formulated for oily and blemish-prone skin, the presence of Alcohol Denat. and active acids may be too potent for extremely sensitive complexions. We recommend consulting our skincare experts who can assess your individual skin concerns and suggest whether this kit is appropriate for your sensitivity level, or recommend alternative SkinCeuticals products better suited to sensitive oily skin.

Q: How does Silymarin differ from other SkinCeuticals Vitamin C serums like CE Ferulic?

A: Silymarin CF is specifically engineered for oily and blemish-prone skin, featuring an oil-free formulation with the addition of 0.5% Silymarin and 0.5% Salicylic Acid to target oil oxidation and provide gentle pore exfoliation. CE Ferulic, whilst equally potent in antioxidant protection, contains Vitamin E and is better suited to normal, dry, or sensitive skin types. Our experts can help determine which vitamin C serum best addresses your specific skin concerns and type.

Q: When will I see results from using this kit?

A: Clinical studies demonstrate that oil reduction can be observed within the first week of use, with participants experiencing up to 15% reduction in excess sebum. Significant improvements in oil oxidation (up to 76%) are evident after four weeks of consistent daily application. Visible improvements in fine lines and wrinkles (up to 24%) typically appear after eight weeks, whilst ongoing use provides cumulative benefits in skin clarity, texture, and protection against premature ageing.

Q: Do I need to use an additional moisturiser with this kit?

A: For most oily skin types, the Silymarin CF serum paired with Oil Shield Defense SPF 50 provides sufficient hydration due to the inclusion of humectants like Glycerin in the sunscreen formula. However, if you have combination skin with localised dry areas, or if environmental conditions are particularly dehydrating, you may layer a lightweight, oil-free moisturiser between the serum and sunscreen. Speak to our experts for personalised layering recommendations based on your specific skin needs.

Q: Can I use this kit alongside other active ingredients like retinol?

A: Yes, the Silymarin CF Kit can be incorporated into a comprehensive skincare routine that includes retinoids. Use Silymarin CF in the morning for antioxidant protection, and apply retinol products in your evening routine. The Salicylic Acid in Silymarin CF works synergistically with retinoids to address both blemishes and signs of ageing, though you should introduce products gradually to allow your skin to build tolerance. Our skincare experts can provide specific guidance on layering and frequency based on your current routine.

Q: Is this kit suitable for use under makeup?

A: Absolutely. The lightweight, oil-free texture of Silymarin CF absorbs rapidly without leaving tackiness, whilst the Oil Shield Defense SPF 50 provides a mattifying, dry-touch finish that serves as an excellent makeup primer. The Silica Silylate technology creates a smooth, refined canvas that helps makeup apply more evenly and last longer throughout the day. Many users report improved makeup wear and reduced need for touch-ups when using this kit as their base layer.
