Effective serum that improves skin texture and hydration
Size: 16 Fl Oz (Pack of 1), Size: 16 Fl Oz (Pack of 1)
I have been using this serum consistently and I can see a clear improvement in my skin. It feels smoother, more hydrated, and more even in texture. It is lightweight, absorbs quickly, and does not irritate my skin. It works well with my other skincare products and I will continue using it. I highly recommend it for anyone looking to improve their skin.

Size: 16 Fl Oz (Pack of 1), Size: 16 Fl Oz (Pack of 1)
My husband has been using this cleanser as part of his daily routine, and it has been a simple and reliable option for keeping his skin clean without feeling dry or tight. The formula is gentle and easy to use consistently. Skin type: normal skin How it’s used: morning and night as a daily face wash What we liked: • Texture: smooth, lotion-like consistency that spreads easily • Gentleness: cleans without leaving the skin feeling stripped • Hydration: skin still feels soft and comfortable after rinsing • Fragrance-free: no strong scent, which is nice for everyday use • Ease of use: works well as a basic, no-fuss cleanser Things to note: • This is a gentle cleanser, so it doesn’t foam much • Best suited for normal to dry skin rather than very oily skin Results after a few weeks: With consistent use, his skin has stayed balanced and comfortable without feeling dry after washing. Overall: This has been a dependable everyday cleanser that’s easy to use and gentle on the skin. It’s a good option for anyone looking for a simple, fragrance-free face wash that doesn’t leave skin feeling tight. Best for: • normal to dry skin • daily morning and night use • anyone wanting a gentle, non-foaming cleanser Update: Added photos to show texture and packaging.

From dry to soft in days.
Style: 3.38 Fl Oz (Non SPF)
I bought this moisturizer at a time when my skin truly needed help, with mature and sensitive skin, and I was dealing with intense dryness. My skin felt tight, dull, and uncomfortable, even after trying several products that didn’t provide lasting hydration. I decided to try this cream and within the first few days, I noticed a real difference. It’s lightweight, absorbs quickly, doesn’t feel greasy, and most importantly, it doesn’t irritate my skin—instead, it soothes it. With continued use, my skin became softer, more supple, and visibly healthier, without that constant tight feeling. I love that it’s fragrance-free, oil-free, and non-comedogenic, as it hasn’t caused any breakouts. It also contains ceramides and niacinamide, and the added SPF makes my routine much easier. After trying many products, I can honestly say this is the only one that truly worked for me. It’s now a daily essential.

Great daily lotion
Style: 3.38 Fl Oz (Non SPF)
Great daily lotion. I love that it is light and fragrance free. It is perfect for day use. I have dry skin and sometimes it is not enough to use by itself. I mostly use it during the day as a base for sunscreen but it feels really good on the face and does not leave my face feeling greasy. The ingredients are really good and the value for money is great. I love LRP products and this is so easy to use.
