Lira Clinical MYSTIQ Intense C 15 Booster with PSC

A high-potency Vitamin C booster designed to brighten, firm, and refine the skin while targeting pigmentation, pores, and overall skin radiance.

Full Description 

Elevate your skin with this advanced, high-performance Vitamin C serum formulated with 15% BV-OSC (Tetrahexyldecyl Ascorbate) a stable, lipid-soluble form of Vitamin C that penetrates deeply to deliver powerful brightening and anti-ageing results.

This intelligent booster works to visibly reduce pigmentation, refine pores, and stimulate collagen production, leaving the skin smoother, firmer, and more luminous. Infused with Lira Clinical’s signature MASQ-tech™ (Mastiha) and Orange Plant Stem Cells, the formula supports skin regeneration, strengthens the dermal structure, and enhances overall skin clarity.

With added Hyaluronic Acid for hydration and antioxidant protection against environmental stress and blue light damage, this serum delivers both immediate glow and long-term skin correction.

The Intense C15 Booster is suitable for all skin types, particularly those experiencing pigmentation, dullness, uneven tone, enlarged pores, or early to advanced signs of ageing. Ideal for clients wanting brighter, firmer, more refined “glow” skin.

Lira Clinical MYSTIQ Intense C 15 Booster with PSC is suitable for use during pregnancy or when breastfeeding.

How It Works

This advanced serum delivers a high concentration of lipid-soluble Vitamin C (15%), allowing deeper penetration into the skin compared to traditional Vitamin C forms. This helps to stimulate collagen production, reduce oxidative stress, and brighten pigmentation at a cellular level.

Mastiha works to regulate pigmentation and reduce inflammation, while Orange Plant Stem Cells support dermal restructuring and improve skin density. Hyaluronic Acid binds moisture into the skin, enhancing plumpness and reducing the appearance of fine lines.

Together, these actives work synergistically to refine pores, even out tone, and restore a more radiant, youthful complexion.

Lira Clinical MYSTIQ Intense C 15 Booster benefits:

• Brightens and evens skin tone
• Reduces pigmentation and dark spots
• Stimulates collagen production
• Refines pores and smooths texture
• Improves firmness and elasticity
• Provides antioxidant protection (including blue light defence)
• Deeply hydrates and plumps the skin
• Supports skin repair and regeneration
