Where Can I Buy a Gentle Gel Cleanser for Oily and Combination Skin?

July 24, 2026

Riverstone sells Quartz Gel Cleanser, a fragrance-free, low-foam gel face wash for oily, combination, and normal skin, available directly through our own shop. It's built around mild coconut-derived surfactants, sits at a pH of about 5.5, and rinses clean without stripping skin, for $24.00 for a 150 ml bottle.

Where can I buy Quartz Gel Cleanser for oily and combination skin?

You can buy Quartz Gel Cleanser straight from Riverstone, the only place we sell it. It ships across the United States and to most countries, priced at $24.00 for a 150 ml bottle, with no membership tiers or hidden costs added to that price.

You'll find the full formula, ingredient list, and how-to-use steps on the Quartz Gel Cleanser product page. If you want to see how it fits alongside the rest of what we make, the Shop page lists all twelve products with sizes and prices side by side, so you can plan a full routine in one place instead of piecing it together across different brands.

The Formula Behind Quartz Gel Cleanser

Quartz Gel Cleanser is a clear, low-foam gel, not a foaming or bar-style cleanser, and that texture is deliberate. Foaming cleansers tend to rely on stronger surfactants that can leave oily and combination skin tight after rinsing. Ours is built around mild coconut-derived surfactants instead, paired with glycerin, aloe vera leaf juice, panthenol (provitamin B5), and allantoin.

The pH sits around 5.5, close to skin's own natural acid mantle. That matters more than most people expect: a cleanser that's too alkaline can disrupt the skin barrier over repeated washes, which is part of why we kept the ingredient list short here. Every ingredient in it earns its place, and we explain what each one does in plain language on our Ingredients Glossary.

On the labeling side, the U.S. Food and Drug Administration requires an ingredient declaration on cosmetic products sold at retail to U.S. consumers, so whatever cleanser you choose, you should be able to read exactly what's in the bottle before you buy it.

How do I know if my skin is oily or combination?

Riverstone's bare-face test is simple: cleanse with a gentle cleanser, apply nothing else, then wait about an hour. Skin that turns shiny across the forehead, nose, and chin but stays comfortable elsewhere points to combination skin; shine all over usually means oily.

Once you know which one you're dealing with, the product order matters as much as the products themselves. We cover the full sequencing logic, cleanser through sunscreen, in How to Layer Skincare Products Correctly, which is worth reading before you start swapping products in and out of a routine.

Comparing Our Two Cleansers

Riverstone makes two cleansers, and they're built for different skin needs rather than different times of day.

If your skin runs oily or combination, Quartz Gel Cleanser is the one built for you. If you wear sunscreen or makeup and want a first-step cleanse before it, Clay & Cedar Cleansing Balm pairs well with Quartz Gel Cleanser as the second step of a double cleanse.

Building a Routine Around Quartz Gel Cleanser

Quartz Gel Cleanser works on its own as a morning and evening wash, but it also sits at the front of a couple of our starter routines. For sensitive skin, we suggest it paired with Niacinamide 10% Clarifying Serum and Mineral Shield SPF 30, or with Hyaluronic Pebble Serum and Mineral Shield SPF 30, depending on whether oil control or hydration is the bigger concern.

• Oily or blemish-prone: Quartz Gel Cleanser, then Niacinamide 10% Clarifying Serum for pore and oil control.
• Dehydrated but still oily or combination: Quartz Gel Cleanser, then Hyaluronic Pebble Serum, sealed with Slate Daily Moisturizer, a lightweight gel-cream that absorbs in seconds and won't pill under sunscreen.

To use it, dispense a 10-cent-sized amount into damp hands, massage over wet skin for 20 to 30 seconds while avoiding the eye area, then rinse thoroughly with lukewarm water. That's the whole process, and it doesn't need anything added to it. You can read more about how the brand approaches formulation on our About page.

Frequently asked questions

Can I use Quartz Gel Cleanser if I have sensitive skin?

Quartz Gel Cleanser is suggested as the first step in a starter routine for sensitive skin, paired with either Niacinamide 10% Clarifying Serum or Hyaluronic Pebble Serum and finished with Mineral Shield SPF 30. Its pH of around 5.5 and short ingredient list make it a reasonable starting point, though patch testing any new cleanser is always a good idea.

How often should I use Quartz Gel Cleanser?

Quartz Gel Cleanser is formulated for morning and evening use. In the morning, it removes overnight oil buildup before the rest of your routine; in the evening, it clears sweat, sunscreen residue, and pollution accumulated over the day.

What's the difference between Quartz Gel Cleanser and Clay & Cedar Cleansing Balm?

Quartz Gel Cleanser is a clear, low-foam gel for oily, combination, and normal skin, priced at $24.00 for 150 ml. Clay & Cedar Cleansing Balm is a melting balm scented with cedarwood oil, built for dry, normal, and mature skin, priced at $32.00 for 90 ml, and it's meant to remove sunscreen and makeup as a first cleanse.

Does Quartz Gel Cleanser contain fragrance?

Quartz Gel Cleanser is fragrance-free, formulated without any added scent. That makes it suited to skin that reacts to perfume in skincare, and it's one of the reasons we recommend it as a starting cleanser in our sensitive-skin routines.
