At the most basic level, gels are active ingredients suspended in a base of water and a thickening agent, such as xanthan gum. Gels tend to be lighter and less moisturizing than creams or lotions, making them a suitable option for those with oily or acne-prone skin. Cooling, refreshing and more readily absorbed than many other topical formulations, gels are often used to deliver active ingredients in anti-cellulite products and in products designed for use around the delicate eye area. With the right ingredients and know-how, topical gels are relatively easy to make at home.

Pour the spring water into a sterilized glass mixing bowl.

Gradually sprinkle the xanthan gum powder into the water; whisking vigorously, using a fork or an egg whisk.

Blend the mixture using a hand-held or stationary blender to remove any lumps. Skip this step, if your mixture is already smooth.

Add your active ingredient to the mixture. For example, adding 10ml of aloe vera concentrate could be added to make a cooling eye gel. Stir well, using a glass stirring rod.

Transfer the mixture to an airtight glass storage jar.
