TIRTIR Pure Vitamin C 24% Face Serum — 1.01 fl oz, Triple Collagen Brightening for Sensitive Skin

TIRTIR Pure Vitamin C 24% Face Serum is a concentrated Korean serum designed to brighten uneven skin tone, support skin firmness with triple collagen, and suit sensitive skin with a mild formulation.

This lightweight facial serum blends a high-concentration vitamin C complex with supporting ingredients to target dark spots, dullness, and loss of elasticity. Formulated for sensitivity in mind and packaged in eco-friendly glass, it aims to fit into morning or evening routines. Apply after cleansing and toning, and follow with sunscreen in daytime to protect skin and maximize results.

How does this serum help reduce dark spots and dullness?

The serum uses a concentrated 24% pure vitamin C blend (listed as 246,750ppm) to help even skin tone and increase radiance over time. Vitamin C is a popular antioxidant for addressing visible discoloration when used consistently alongside sun protection. Results vary by individual and depend on routine consistency.

• High-strength 24% vitamin C concentrate for targeting pigmentation
• Formulated to boost overall brightness and minimize dullness
• Designed for daily use in a regular skincare sequence

Will this serum irritate sensitive or reactive skin?

Although the formula emphasizes mildness and sensitivity-friendly components, higher vitamin C concentrations can cause tingling for some users. The serum includes 0.5% alpha-bisabolol, a calming ingredient that helps reduce visible redness and irritation. Patch-test before full-face use and introduce gradually to assess tolerance.

• Lower-irritation support via 0.5% alpha-bisabolol
• Suitable for gradual introduction into sensitive skin routines
• Remove advances immediately if persistent discomfort occurs

How does the triple collagen aspect affect skin firmness?

Triple collagen in the formulation aims to improve the feel of elasticity and support a firmer-looking complexion when used regularly. Collagen-containing topical products primarily hydrate and plump the skin surface, contributing to a smoother appearance. Combine with consistent skincare and healthy lifestyle choices for best outcomes.

• Triple-collagen complex to help support surface firmness
• Hydrating effect that can reduce the look of fine lines
• Works best as part of a complete anti-aging or maintenance routine

How should I use TIRTIR Pure Vitamin C 24% Serum in my routine?

Use the serum after cleansing and toning, applying a suitable amount and smoothing until absorbed. For daytime, follow with a broad-spectrum sunscreen SPF 30 or higher to protect skin and help maintain visible improvements. At night, you can layer with lightweight moisturizers if needed.

• Apply to clean, dry skin; smooth in until fully absorbed
• Use morning only if you will apply SPF afterward; otherwise use at night
• Introduce slowly if new to high-concentration vitamin C

Who is this for: This serum is intended for users seeking a potent vitamin C product that targets uneven tone, supports surface firmness, and is formulated with sensitive skin considerations. Ideal for people wanting a Korean-style, high-concentration brightening option in an eco-conscious glass bottle; not recommended for those who have previously reacted strongly to concentrated vitamin C without prior acclimation.
