Even though I have dry skin, this product was easy to use all year round! When I apply makeup after using it, the finish of my skin is definitely different! It gives me a glow like a boiled egg. I have dry skin, but this product itself isn't too oily, so I think it would be fine for those with oily skin too! It really protects my skin during this time of year when the seasons are changing!!
I tried the recently popular "OSOF Watery Skin Booster." It's a booster that you use after your skincare routine and before your cushion foundation, and it's amazing! First of all, the texture is so light, it absorbs into your skin like water. It's not sticky, but it's moisturizing and leaves your skin looking dewy and radiant, which is great. If you apply this and then the cushion, your foundation will adhere much better, it softly covers your pores, and it gives you a natural glow. It's so time-saving that you could say, "This is all you need for your pre-makeup skincare routine!"
If you're wondering whether to buy a primer, give this a try! It truly does eliminate the "heaviness of primers" and feels like an essence. While many products are moisturizing only on the surface and dry inside, this skin booster's fundamental goal is to keep your skin hydrated all day. Its light, silky texture blends seamlessly into your skin without creasing or stickiness, even when layered. And what's even more important! My foundation doesn't smudge or flake, leaving my skin looking incredibly refined. And what's even more amazing is that it doesn't feel like I'm wearing anything at all; it gives off a soft, natural glow. It's not a greasy glow, but a dewy glow that seems to emanate from within. It makes my skin look beautiful, and it really lifts my spirits every time I put on makeup. I didn't feel any tightness until I cleansed it at night, and I didn't experience any dryness all day. I'm starting to wonder, "What did I ever do without it...?" This product alone gives you moisture, improves skin texture, and makes your makeup stick better, so I no longer use a primer. This is all I need! Conclusion: If you're looking for true moisturizing that goes beyond just the surface, or if you're looking for a replacement for a primer, you should definitely give it a try. OSOP really never disappoints.
Can you see the clear light in the photo? I have dry skin, and I used to have a lot of trouble with oil rising on the surface over time. Maybe that's why my makeup would come off easily after a while after I applied it. But it's been over 10 hours since I started using this skin booster, and my makeup still looks as good as it did when I first started, so I was surprised and took a photo! I often hear that this product improves skin, so I always take it with me when I travel. All my friends have heard about it and recommended it to me! Trust me, give it a try!
