Geologie Vitamin C+E Ferulic Face Serum — 30 mL light-protected pump, 5% stabilized vitamin C for brightening and firming

Geologie Vitamin C+E Ferulic Acid Face Serum is a stabilized, light-protected antioxidant serum formulated to brighten skin, support firmness, and reduce visible signs of aging using 5% vitamin C, 0.5% vitamin E, and ferulic acid.

This lightweight gel-serum combines a stabilized form of vitamin C with vitamin E, ferulic acid, and hyaluronic acid to help even skin tone, support collagen-related firmness, and hydrate without heavy residue. Packaged in an airless, light-protected pump, the 30 mL formula is designed to preserve potency while remaining suitable for daily morning use under sunscreen.

How does this serum brighten and even skin tone?

The serum uses a 5% stabilized vitamin C blend plus ferulic acid to target surface discoloration and help reduce the look of dark spots and uneven tone. Vitamin C helps regulate pigment-producing pathways, while ferulic acid enhances antioxidant stability.

• 5% light-protected, stabilized vitamin C to reduce dullness and hyperpigmentation over time
• Ferulic acid to bolster antioxidant effect and protect vitamin C from oxidation
• Vitamin E complements antioxidant action to support a more even complexion

Will this improve firmness and reduce fine lines?

The formula is designed to support collagen-building processes associated with firmer-looking skin through antioxidant activity rather than invasive treatments. Consistent use can help skin appear smoother and more resilient by protecting against oxidative stress that contributes to visible aging signs.

• Antioxidant blend helps reduce environmental damage that accelerates collagen breakdown
• Hyaluronic acid (1.5%) attracts and holds moisture for plumper-looking skin
• Lightweight gel texture layers easily under moisturizer and SPF

How should I add this serum to my routine and is it suitable for sensitive skin?

Apply 2–3 pumps to cleansed skin in the morning, then follow with moisturizer and broad-spectrum SPF. The airless, light-protected pump helps maintain potency and reduce irritation risk, making it approachable for many skin types, including those new to vitamin C.

• Use 2–3 pumps on face after cleansing in the AM for best results
• Follow immediately with moisturizer and SPF to protect against sun-induced damage
• Airless packaging and stabilized formula minimize oxidation and potential sensitivity

How long until I notice results and how long does a 30 mL bottle last?

Visible improvements in brightness and texture can appear within weeks for some users, though individual results vary based on skin condition and consistency of use. A 30 mL bottle used daily as recommended typically lasts one to three months depending on pump usage.

• Some users report brighter tone and improved texture in a few weeks with regular use
• Stabilized, light-protected format preserves effectiveness during the bottle’s lifespan
• 30 mL size is travel-friendly and fits easily into morning skincare routines

Who is this for: Geologie Vitamin C+E Ferulic Acid Face Serum suits anyone seeking a daily antioxidant boost to address dullness, uneven tone, early signs of aging, and hydration without heavy creams. It’s appropriate for people new to vitamin C and for those who prefer a stable, light-protected product packaged to maintain potency. Avoid use on broken skin and patch-test if you have known sensitivities to actives.
