Yonka Vitamin C Serum 20% Concentrated Oleo-Serum, 1.01 fl oz — Oil-Soluble, Lightweight Anti-Aging Radiance

Yon-Ka 20% Vitamin C Serum is a concentrated, waterless oleo-serum that delivers a stabilized 20% vitamin C to help even skin tone, firm texture, and support visible radiance.

This lightweight, oil-soluble serum combines a high concentration of stabilized vitamin C with plant cell extracts to target dullness, discoloration, and the appearance of aging. Formulated with 99.9% natural-origin ingredients and a waterless base, the serum preserves potency while providing a non-greasy finish that layers easily under creams or makeup.

How quickly will I notice changes in skin tone and radiance?

Visible improvements can appear within weeks when used consistently; consumer testing monitored by dermatologists reported measurable evening of skin tone and reduction in uneven areas over regular use. Individual results vary by skin type and prior skin condition.

• Use morning and evening for accelerated results.
• Instrumental tests showed tone evenness increases with continued application.
• Combining with sun protection helps maintain results and prevent further darkening.

What makes this vitamin C different from other serums?

This formula uses an oil-soluble, stabilized form of vitamin C (ascorbyl tetraisopalmitate) that resists oxidation and stays effective in a water-free oleo-serum. The waterless delivery helps maintain potency and yields a lightweight, non-comedogenic feel that won’t leave skin oily.

• 20% concentration for a high-strength treatment.
• Oil-soluble vitamin C for improved stability and skin penetration.
• Preservative- and alcohol-free, suitable for layering under other products.

Can I use this after professional skin procedures or with other products?

The serum is formulated so it can be integrated into both daily routines and short intensive courses; Yon-Ka indicates compatibility with post-procedure care like injections or microneedling when advised by your clinician. Always follow your practitioner’s guidance after treatments and introduce the serum gradually if you have sensitive skin.

• Apply alone or before your moisturizer morning and night.
• Safe to combine with most creams; avoid mixing with unstable vitamin formulations simultaneously.
• If post-procedure, consult your provider before resuming active treatments.

What texture and finish should I expect from the serum?

The product is a lightweight, non-greasy oleo-serum that absorbs quickly without clogging pores. Formulated to be non-comedogenic and free of alcohol, it leaves a comfortable, hydrated feel that preps skin for moisturizers or makeup.

• Waterless texture preserves active ingredients and minimizes oxidation.
• Finishes dry-to-satin so it layers well under sunscreen and foundation.
• Includes apricot kernel oil for lightweight moisturization and skin comfort.

Who is this for: This Yon-Ka serum suits anyone seeking a potent, natural-origin vitamin C treatment to address dullness, uneven pigment, and early signs of aging—especially those who prefer stable, oil-soluble vitamin C in a lightweight formula. It is appropriate for most skin types seeking to boost radiance and tone when used as part of a consistent skincare routine; consult a dermatologist if you have very reactive skin or recent invasive procedures.
