Since I started using this product, I've noticed that my acne scars have gradually faded! Even though it contains aggressive ingredients, I haven't noticed any irritation to my skin so far! It spreads easily when applied, and even a small amount can be applied over a wide area.
Luminous HQ Booster is a pre-treatment serum that penetrates directly into the core of translucency, restoring a brighter skin tone. It's designed for those who are concerned about lack of firmness, elasticity, and dullness. It's applied after cleansing and before applying lotion. It spreads smoothly and I really like the scent. I've only been using it for a few days, so I can't really see the effects, but it absorbs the lotion well and is very comfortable to use.
I received this product as a gift from Suzykirei. The scent is refreshing, but with a hint of sweetness. I'm not particularly fond of scented cosmetics, but the scent of this product isn't too strong, so I didn't find it unpleasant. The texture is thick and blends well with the skin, and it felt like it was quickly absorbed after spreading it. However, because it contains the Shiratama fermented peeling effect, there is a slight tingling sensation immediately after application. The tingling sensation goes away as it absorbs, but if your skin is sensitive, it may be best to refrain from using it. I've only used it a few times, so I haven't noticed any significant improvement in my skin clarity yet, but I hope that with continued use, my skin clarity will improve.
I tried using this pre-treatment serum, which is great for dark spots! I use it right after washing my face, and it spreads easily and blends in easily, so I feel like the lotion I apply afterward penetrates well. I haven't noticed any redness, and I've been using it. I feel like the dark spots that I've been worried about as I've gotten older are gradually improving. The best thing about it is that my makeup goes on better!
