Skinfix Vitamin C Serum Brighten + Firm 15% THD Vitamin C — 2% Peptides, Gentle for Sensitive Skin

Skinfix Brighten + Firm 15% Vitamin C Serum is a gentle, high‑potency daily serum that targets dark spots and fine lines while improving overall radiance.

This lightweight serum combines a stable, skin‑friendly form of vitamin C with peptides and supportive hydrators to visibly even tone and support firmness without provoking irritation. Developed to be used morning and night, the formula prioritizes efficacy and tolerability, so people with sensitive or aging skin can introduce vitamin C benefits without common stinging or redness.

How quickly will I see brighter, more even skin?

Most users notice improved radiance and softening of fine lines within a few weeks, with continued improvement over a month as pigment and texture respond to consistent use. Results depend on individual skin type, the degree of hyperpigmentation, and daily sun protection habits.

• Formulated with 15% tetrahexyldecyl ascorbate, a stable vitamin C derivative for gradual brightening.
• Contains a 2% tetrapeptide blend to reduce the appearance of dark spots.
• Clinical testing reported visible improvements within one month for most participants.

Will this vitamin C serum irritate sensitive or reactive skin?

The serum is designed to be mild: it uses a less acidic, oil‑soluble form of vitamin C and omits fragrances, essential oils, and other common irritants. Clinical results showed tolerability even with twice‑daily application, but patch testing is still recommended for reactive skin types.

• No fragrance, essential oils, silicones, parabens, sulfates, or PEGs.
• Reported gentle on skin during two‑month, twice‑daily testing.
• Vegan, cruelty‑free, and formulated to minimize common sensitizers.

How should I use this serum in my routine for best effect?

Apply 1–2 pumps to freshly cleansed, dry skin before moisturizer, in the morning and/or evening. Because it’s formulated for stability and gentleness, it can be layered under sunscreen during daytime to help prevent new pigmentation.

• Use after cleansing and before moisturizers or oils.
• Apply 1–2 pumps to face and neck; follow with SPF during daytime.
• Safe for twice‑daily use as part of a consistent regimen.

What key ingredients deliver visible brightening and firming?

The formula centers on a 15% concentration of tetrahexyldecyl ascorbate, a stable vitamin C ester that penetrates skin to support brightness. Peptide complexes and hydrating agents complement the vitamin C to address texture, elasticity, and moisture for a more even, resilient appearance.

• 15% THD Vitamin C for luminous tone and antioxidant support.
• 2% Tetrapeptide solution to help reduce dark spots and hyperpigmentation.
• 2% PGA peptide solution to restore bounce, plus 5% glycerin for hydration.
