🌿 Product Formulation Breakdown
🌳 ROUND LAB Birch Juice Moisturizing Sunscreen
A long-standing K-beauty favorite, this sunscreen combines SPF50+ PA++++ protection with a moisturizing formula powered by Birch Sap (1,425ppm), niacinamide, and hyaluronic acid. It hydrates, calms, and strengthens the skin barrier — basically a skincare cocktail with sun protection benefits.
🍚 Beauty of Joseon Relief Sun Aqua Fresh Rice+B5
A lighter, fresher follow-up to the original Relief Sun, this SPF50+ formulation features rice seed water, panthenol (B5), and oat kernel extract. It uses 5 modern chemical UV filters for broad-spectrum protection, while maintaining a non-greasy, breathable texture.
🧴 Texture & Application
ROUND LAB
Think “moisturizer with SPF.” It spreads smoothly, feels silky, and absorbs fast. You’ll notice the hydration immediately — without tackiness. Its slightly creamier feel makes it ideal for drier skin types or cool-weather wear.
BoJ Aqua Fresh
As the name suggests, it’s super watery and lightweight. It absorbs almost instantly, leaving no greasy finish or film. Perfect for people who hate the feel of sunscreen or want that “barely-there” experience.
✨ Finish & Feel on Skin
ROUND LAB leaves a subtle satin finish with a hint of glow — not oily, just healthy. It’s deeply hydrating and often used as a 2-in-1 moisturizer + sunscreen.
BoJ Aqua Fresh dries down semi-matte, leaving your natural skin tone and texture visible. Zero white cast, zero residue — like it was never there.
💄 Makeup Compatibility
- ROUND LAB: Excellent under makeup. Creates a cushiony layer that grips foundation without sliding or pilling. Even reapplication over makeup works with minimal effort!
- BoJ Aqua Fresh: Works like a lightweight primer. Great for oily/combo skin wearers who want a non-slippery SPF layer under foundation or tint.
⚠️ Sensitivity Check
While ROUND LAB is widely loved, some users have reported reactions due to the birch sap — especially those with springtime or pollen-related allergies.
BoJ Aqua Fresh is unscented, designed for sensitive skin, and features calming ingredients like oat and panthenol. So far, fewer reports of irritation have surfaced — a safer pick for reactive skin types.
💰 Price & Value
ROUND LAB usually retails for around $28 but can drop to as low as $11.99 during sales. You get 50ml of product that works double duty as SPF + moisturizer.
BoJ Aqua Fresh is in a similar range (typically $15–$25), also with 50ml. It’s more of a pure sunscreen, so oily-skin users may still want a light moisturizer underneath.
