This is a large, 500 ml bottle of Hollyberry retinol serum, so it should last ages.   Only a very small amount of the serum is needed, as a little goes a long way. It applies easily and absorbs quickly. I suffer from dry, sensitive skin but haven’t had any redness, itching, or other adverse reactions while using it.   I’ve been applying it at night and then using my normal moisturiser afterwards. My face does feel softer, but I can’t say I’ve noticed any significant changes in how my skin looks, although it is still early days.   It's a bumper-sized bottle and good value for money (if it works).   Thank you for taking the time to read my review. I hope you found it helpful.

I am pleased to have discovered the Retinol Serum by Hollyberry Cosmetics as this product has really been good for my skin. First and foremost, the extra-large 500ml bottle is a fantastic value for money. It ensures that I have a plentiful supply of this hood serum, allowing me to incorporate it into my daily skincare routine without worrying about running out anytime soon. One of the key ingredients in this serum is Vitamin A, in the form of retinol. Retinol is widely known for its remarkable anti-aging properties, and this serum harnesses its power to the fullest. I've noticed a significant improvement in the texture and tone of my skin since I started using it. My skin looks smoother and more youthful overall. Another noteworthy component of this serum is hyaluronic acid. This ingredient provides excellent hydration, leaving my skin feeling plump, moisturized, and nourished. I appreciate that the formula is lightweight and absorbs quickly, allowing me to apply it before my moisturizer without any greasy residue. What sets the Retinol Serum by Hollyberry Cosmetics apart from other products I've tried is its advanced formulation. The serum is carefully crafted to deliver maximum results while minimizing any potential skin irritation. I have sensitive skin, but I haven't experienced any redness or discomfort with this serum. It's gentle, yet highly effective. The bottle is sleek and practical that ensures hygienic and controlled usage. Overall, I am very pleased with this product which I can recommend.

Nice large bottle that will last for ages as only a small amount is needed. Sinks into face well and leaves skin feeling soft and hydrated. My skin has felt less dry in the morning. I don't like the smell but it doesn't put me off. Won't see any results in my skin yet as I will need to use it a while longer but so far I like it.

Ive been looking for a vitamin a serum to use on my body, so was happy to find this large bottle! I apply at night as vitamin a increases sensitivity to the sun, which can lead to pigmentation. I have seen a small improvement to my skin so I’m more than happy with that. ⭐️⭐️⭐️⭐️

With 500ml of serum, it'll take me a long time to work my way through this. The texture of the serum is nourishing and it smooths well onto my face, neck, arms and hands. It has good 'slip' so it massages well onto the skin, and can be layered under your moisturiser or body cream. I think it's good value as well, and am enjoying using this serum. I have enjoyed using it at night before going to bed. It has no odour so you can integrate it into your skincare regimen. It is a large bottle so you might consider buying a smaller bottle with a dropper and decanting for convenience.
