GLYTONE Age-Defying Vitamin C Serum 20% THD Ascorbate — 1 fl oz, Vitamin E & Squalane for Brightening & Hydration

Glytone Age-Defying C+ is a daily antioxidant serum with 20% vitamin C, vitamin E and squalane designed to brighten skin, support hydration and reduce the look of fine lines.

This lightweight facial serum combines a stabilized form of vitamin C (THD ascorbate) with vitamin E and squalane to target uneven tone, environmental damage and moisture loss. Fast-absorbing and fragrance-free, the formula is created to layer easily under sunscreen and makeup and to fit into morning or evening routines. The product description below explains how it works, what to expect and who will benefit most from regular use.

How does this serum help skin brightness and dark spots?

The concentrated 20% THD ascorbate delivers antioxidant support that helps reduce visible discoloration and promotes an even-looking complexion. Vitamin C works alongside vitamin E to neutralize free radicals that can contribute to dullness, while regular use supports a clearer, more radiant appearance.

• 20% stabilized vitamin C (THD ascorbate) for targeted brightening
• Vitamin E for complementary antioxidant protection
• Formulated to help fade dark spots and even skin tone with consistent use

Will this serum hydrate without feeling heavy or sticky?

Yes — the addition of squalane offers lightweight, lasting hydration that helps fortify the skin barrier without leaving a greasy finish. The serum absorbs quickly, making it suitable to wear under makeup or sunscreen throughout the day.

• Squalane provides softening, non-comedogenic moisture
• Fast-absorbing texture that layers well under other products
• Designed to maintain hydration while smoothing the appearance of fine lines

Is this formula appropriate for sensitive or acne-prone skin?

The formula is free of parabens and fragrance, which reduces potential irritation for many users. Because it uses a stabilized vitamin C and a gentle oil-based hydrator, it tends to be well tolerated, though patch testing is recommended if you have very reactive skin.

• Fragrance-free and paraben-free to minimize irritants
• Non-comedogenic squalane suitable for most skin types
• Patch test advised for very sensitive or allergy-prone skin

How should I use this serum in my daily routine?

Apply a few drops to clean, dry skin once daily — morning is ideal for antioxidant protection, but it can also be used at night. Follow with a broad-spectrum sunscreen during the day, and layer moisturizer as needed to lock in hydration.

• Use 2–3 drops on face and neck after cleansing and toning
• Apply sunscreen each morning after the serum for UV protection
• Can be used under moisturizer or makeup without pilling

Who is this for: Glytone Age-Defying C+ is formulated for people seeking a potent antioxidant serum to brighten skin, reduce the visible signs of aging like fine lines and improve hydration. It suits those who want a lightweight, fragrance-free option that layers well with sunscreen and makeup—ideal for normal, combination, dry, or oil-prone skin types, though very sensitive users should patch test first.
