Review: Gentle, Effective & Great for Acne-Prone Skin — Just Wish It Came in More! - ’ve been using the numbuzin No.5 Vitamin Concentrated Serum every single day, and it has truly become a staple in my skincare routine. As someone with acne-prone skin, I’m always cautious with vitamin serums because many can feel heavy or trigger breakouts. This one has worked beautifully for me. The formula is lightweight, absorbs quickly, and doesn’t leave any sticky or greasy feeling. It layers well under moisturizer and sunscreen without pilling. Over time, I’ve noticed gradual improvement in dullness and post-acne marks. My skin looks brighter and more even, but still feels calm and balanced — not irritated or overwhelmed. Pros: * Lightweight and fast-absorbing * Gentle on acne-prone/sensitive skin * Helps with dullness and post-acne marks * Suitable for daily use Cons: *The quantity feels a bit less for the price, especially if you use it daily Overall, it’s a gentle yet effective vitamin serum that works well for everyday use. I just wish it came in a slightly larger bottle!
Review: Right Ingredients, Gentle but SLOW FADING over 3+ months - 3-MONTH RESULTS (2x day): Slight fading of deep dark acne scars and age spots. Evens out skin tone. Gentle and not irritating. I am guessing this will take 6 to 9 months for deeper scars to fade. The pamphlet on Yesstyle.com shows 9.65% improvement in Blemishes after 4 weeks and 18.9% for even skin tone (this means expect slow steady results). They recommend also using the toner pad for faster results (165% improvement) but the combo irritated my skin. Overall, I like that it is gentle and will continue using it, right after the Toner. KEY INGREDIENTS: Contains the right chemicals known to fade dark spots like Glutathione, 4% Tranexamic Acid, 5% Niacinamide (both suppresses melanin), Alpha-Arbutin, Vit C, 3-0-Ethyl Ascorbic Acid, Tumeric etc. TEXTURE: Light serum, not sticky, absorbs quickly after Toner. Tap face gently for a few seconds after applying to help the skin absorb quicker before adding the next product (tip from korean skincare companies that works). ACNE PREVENTION TIPS: Best way to see improvement of skin is to keep the pores clear and acne from re-surfacing. I have not had a single breakout in 3 months using this routine. Also changed my skin type from Oily Combo to Normal. STEP 1 (2x day) - Use SEBUM CONTROL TONER to regulate skin oil production (I use NUMBUZIN No. 1 blue bottle) STEP 2 (2x day) - Use ANTIBACTERIAL SERUM to reduce inflammation (I use Beauty of Joseon Glow Serum w/60% propolis, Tea Tree) STEP 3 (2x week) - EXFOLIATE to keep pores clear, as clogged pores breed acne. I use Beauty of Joseon Ground Rice and Honey mud mask. Leave on face and neck for 15 minutes; this is a very gentle product. STEP 4 (Optional) - EAT food that aide the digestive system and help prevent acne like Yogurt, Kimchi and Sauerkraut (eat small amounts 2-3 times a week). I hope these tips are helpful to everyone.
