Kira 60˚ C-Tide Serum

Kira 60° C-Tide Serum is formulated for all skin types — dry, dehydrated, oily, combination, and sensitive. Its lightweight gel texture absorbs instantly without stickiness or residue, making it comfortable for daily use on any skin type. It is especially effective for skin showing early signs of aging such as fine lines, loss of firmness, uneven tone, or persistent dullness.

Kira 60° C-Tide Serum delivers six key benefits in
one formula: it visibly reduces fine lines and wrinkles, improves skin
elasticity and firmness, brightens and evens skin tone, strengthens the skin
barrier, provides deep hydration, and supports cellular skin regeneration. It
is powered by patented Centella and Ginseng Exosome technology — a
next-generation delivery system that transports active ingredients directly
into skin cells for deeper, faster, and more visible results than standard
serums.

A serum is a lightweight, highly concentrated formula designed to penetrate deeper into the skin than a moisturizer or cream. It delivers active ingredients — such as peptides, exosomes, and niacinamide — directly to where they are needed most. A cream then seals in those benefits and provides surface protection and lasting hydration. For best results, always apply Kira 60° C-Tide Serum first, then follow with Kira 60° C-Tide Cream. Together they function as a complete anti-aging system.

Yes. Kira 60° C-Tide Serum is EWG Green Grade 1 certified, meaning every ingredient has been evaluated and confirmed safe. The formula is free from parabens, sulfates, artificial fragrances, and silicones. It has passed a clinical skin irritation test and is hypoallergenic certified. It is safe for daily use on sensitive, reactive, or post-procedure skin.

Most users notice softer, more hydrated skin within the first 3 to 5 days. Visible improvement in skin tone, brightness, and texture typically appears within 2 to 3 weeks. Significant improvement in fine lines, firmness, and elasticity is usually visible after 4 weeks of consistent daily use — morning and evening. Results improve progressively with continued use.

Yes. Kira 60° C-Tide Serum contains Acetyl Hexapeptide-8, a clinically studied peptide that visibly reduces expression lines by relaxing the facial muscle contractions responsible for wrinkle formation. Combined with patented Centella and Ginseng Exosome technology that supports cellular regeneration and collagen synthesis, the formula targets fine lines and wrinkles from multiple biological pathways — without the irritation or sensitivity associated with retinol.

No. Kira 60° C-Tide Serum does not contain retinol. Instead, it uses Acetyl Hexapeptide-8 — a clinically studied peptide that delivers comparable anti-aging results without the peeling, redness, or sun sensitivity that retinol can cause. It is safe for daily use morning and evening, suitable for sensitive skin, and does not require a skin adjustment period.

Key ingredients include: Centella Asiatica Exosome (CICASOME, Patent No. 10-2257524) for skin barrier repair, soothing, and regeneration; Ginseng Exosome (Patent No. 10-2445516) for antioxidant protection, elasticity improvement, and anti-inflammatory action; Acetyl Hexapeptide-8 for visible wrinkle reduction; Niacinamide (Vitamin B3) for skin tone brightening and pore refinement; Vitamin C Derivative for luminosity and antioxidant protection; Neuropeptides and 70+ Plant-Derived Extracts for comprehensive skin nutrition and barrier support; and Panthenol and Allantoin for calming and accelerated skin recovery.

Kira 60° C-Tide Serum does not contain retinol, parabens, artificial fragrances, or other ingredients commonly avoided during pregnancy. The formula is EWG Green Grade 1 certified and 100% vegan. However, as with any skincare product, we recommend consulting your healthcare provider before use during pregnancy or breastfeeding.

Yes. Kira 60° C-Tide Serum is certified vegan by KIVAC, using 100% plant-derived ingredients with zero animal-derived substances. No animal testing is conducted at any stage of production or development. The brand holds both Vegan and No Cruelty certifications, and all products are registered with CPNP — the European cosmetic safety standard.

Yes. Kira 60° C-Tide Serum is formulated for both morning and evening use. In the morning, apply it after cleansing to create a brightening, firming base before your cream and makeup. In the evening, it works as an intensive overnight repair treatment — supporting the skin's natural nighttime regeneration cycle to restore elasticity, radiance, and firmness by morning.

Dispense 2 to 3 pumps of serum into the palm of your hand. Gently press and pat the serum onto cleansed skin — forehead, cheeks, nose, and chin. Allow it to absorb fully for 30 to 60 seconds before applying your next product. Follow with Kira 60° C-Tide Cream to seal in the active ingredients. For intensive care 2 to 3 times per week, apply a double layer and allow it to absorb for 5 minutes before the cream step.

Exosomes are nano-sized biological particles that act as smart delivery vehicles, transporting active ingredients directly into skin cells — far deeper than conventional serums or creams can reach. In Kira 60° C-Tide Serum, two patented plant-based exosomes are used: CICASOME (from Centella Asiatica) for barrier repair and soothing, and Ginsenoside Exosome (from Ginseng) for antioxidant protection and elasticity improvement. This technology is considered the next generation of active ingredient delivery in clinical skincare.

Kira 60° C-Tide Serum stands out through its combination of two patented plant-based Exosome technologies, a multi-peptide complex including Acetyl Hexapeptide-8, Niacinamide, and 70+ botanical extracts — all in a single lightweight formula. It is EWG Green Grade 1 certified, vegan, CPNP registered for European standards, and FDA registered under MoCRA for the US market. Few Korean serums available in the USA combine this level of biotechnology with this level of international certification.

Yes. Kira 60° C-Tide Serum is available in the United States exclusively through VEZHA LLC — the official US distributor of ZISU'C — at zisuc.us.
