All DrLOUIE products are safe for people with sensitive skin to use. However, we use highly functional active ingredients. This means that you’ll see results, but if you are allergic, then you may react to certain ingredients. That is why we strongly recommend you do a patch test before using it on your face so that you’ll know whether you are allergic or react to certain ingredients in our products.

If you do not have any visible dark spots or wrinkles, we recommend using All-in-One Essence only for overall brightening and anti-aging effects because using too much isn't helpful for the skin. But if you have visible spots or wrinkles you want to target, you can use Revitalizing Dark Spot Serum on those areas. Please note that Revitalizing Dark Spot Serum is highly-concentrated and highly functional, so we do not recommend using this product all over your face. If you are more concerned with lack of elasticity and wrinkles, we recommend Skin Firming Concentrate. As with Revitalizing Dark Spot Serum, we recommend using Skin Firming Concentrate on saggy areas and on wrinkles.

We recommend using a few drops on the face. But if you have dry or extremely dry skin, you can repeat the step and dab a few more drops on the face. If your skin still feels dry after repeating the step one or two times, we recommend using Age Defying Night Cream and/or Age Defying Day Cream. Usually, our skin gets drier and loses more moisture at night, so you can start with Age Defying Night Cream. You can use our Day Cream or our Protection Cream if you want extra protection against the sun and weather elements.

Essentially, All-in-One Essence Original, Light and Oil-free contain similar ingredients for same effective anti-aging and brightening effects. However, they differ in the percentage of ingredients used to emphasize different functions. All-in-One Essence Original is for people with dry skin and focuses more on anti-aging and wrinkles. All-in-One Essence Light is for people with combination skin and focuses more on tightening pores. All-in-One Essence Oil-free is for those with semi-dry to combination skin who want a non-oily finish. But just because it’s oil-free, it doesn’t mean it’s not as moisturizing. It’s perfect for women and men to use during summer time.
