HKH Vitamin C & Retinol Serum for Face – Day & Night Capsule Skincare

Complete Day & Night Care in One System

HKH offers a dual-phase serum system that combines daytime Vitamin C capsules with night-time Retinol capsules. This 38+38 capsule set is designed for a seamless skincare ritual, pairing brightening and smoothing actions across two steps. The formulations are housed in individual capsules to maintain freshness and potency, so each use feels like a clean, precise application.

Daytime Vitamin C Capsules — Brighten, Hydrate, Protect

The daytime capsules fuse Vitamin C with Niacinamide and Vitamin E to help brighten the complexion, promote an even tone, and deliver lightweight hydration. The combination aims to leave skin looking more radiant and refreshed under daily lighting, with a smooth, comfortable finish that layers well with sunscreen and makeup.

• Potential brightening and more even-looking tone with Vitamin C and Niacinamide
• Hydration that leaves a silky feel without a sticky residue
• Antioxidant support from Vitamin E to help defend against environmental stress

Nighttime Retinol Capsules — Smoothing and Elasticity Support

The night capsules introduce a Retinol-based formula designed to smooth fine lines and improve skin texture by morning. While results vary, users may notice a more even, refined surface and a firmer feel with consistent use over time.

• Targeted for smoother texture and improved surface feel
• Individually sealed capsules preserve freshness and potency
• Designed for easy, mess-free nighttime application

Packaging, Use, and Real‑World Benefits

The 38 daytime plus 38 nighttime capsules come in a travel-friendly setup that travels well and fits into a simple daily routine. Each capsule is a precise dose, designed for clean handling and hygienic use, making it convenient for busy days or on-the-go skincare.

• Individually packed capsules protect the formula from light and air
• Compact, portable set for on-the-go skincare
• Easy to use: after cleansing, rotate the capsule tip and apply to the face

How to Use
