Description
The AHC Masters Icy Jelly Sun Stick 14g is a cooling SPF 44 PA+++ sunscreen stick with a patented jelly texture that cools the skin by -6°C after a single application. It is a triple-function formula for brightening, wrinkle improvement and UV protection, with long-lasting hydration. It suits anyone who wants refreshing, portable sun protection for hot days and quick touch-ups, including over makeup.
Why This One
- Patented jelly texture (Korean Patent No. 10-2789459): the first of its kind from AHC, so it glides on cool and moist instead of feeling waxy.
- -6°C temporary cooling after just 1 use: clinically tested on 30 participants, giving instant relief on hot days.
- +117.0% skin-surface hydration after 1 use, with 48-hour moisture: sun protection that also keeps skin hydrated.
Key Features
- SPF 44 PA+++ protection from a chemical-filter (organic) formula.
- Triple-function care for brightening, wrinkle improvement and UV protection.
- The patented jelly texture is bouncy and soft. It adheres with a cool feel and spreads evenly along the contours of the skin without gaps.
- Delivers an instantly cold feel on application, comparable to a sunscreen stick stored in the refrigerator, even when kept at room temperature.
- Temporary -6°C cooling after a single use, measured on the face. Clinical test by KC Skin Clinical Research Center, 30 participants, December 15–16, 2025. Individual results may vary.
- Instant, long-lasting moisture with 48-hour hydration.
- Hydration improvement measured in the epidermis (0–20 μm) after a single use:
- Skin surface (layer 0): +117.0%
- Layer 5: +127.9%
- Layer 10: +116.2%
- Layer 15: +109.6%
- Layer 20: +86.8%
This test was run by KC Skin Clinical Research Center on the forearm of 30 participants, December 24–31, 2025. Individual results may vary.
- Its strong cooling sensation also cares for skin exposed to infrared heat.
- Masters Make-Up Fit Technology combines a hydrophilic polymer with collagen and G.A.P. It gives a moist, comfortable fit so makeup sits smoothly on top.
- Completed 3 safety tests:
- Suitability for sensitive skin: 30 participants, 24-hour patch.
- Eye irritation alternative test: in vitro.
- Primary skin irritation: 32 participants, 24-hour patch.
- The twist-up dial and compact stick format make it easy to carry and reapply on the go.
How to Use
- At the last step of your skincare routine, turn the dial at the bottom of the container to raise about 5mm of product.
- Spread lightly over the face from the inside outward.
- Carry it with you and reapply frequently to any area that needs UV protection.
- Because of the moist, soft hydrating jelly texture, apply gently without pressing too hard.
Key Ingredients
- Collagen T4: a collagen whose active amino acid sequence matches human collagen COL4A1. This applies to the raw material’s characteristics.
- Canadian Whistler glacier water: a pure glacier water.
- Aloe Barbadensis Leaf Extract: a plant extract.
- Opuntia Ficus-Indica Stem Extract: a cactus extract.
- G.A.P. (Glutamine, Glycine, Cystine): part of the Make-Up Fit Technology for a moist, comfortable fit.

Cautions
- Apply gently and do not press hard, because the jelly texture is soft.
- Beads of water may form on the surface when you open the cap. This sweating is a natural result of the cool, moist jelly texture and is safe.
- Do not discard the clear inner cap. Replace it firmly after every use to preserve the moist feel and bouncy texture.
