Take the skin testDelivering the potency of retinol with minimal irritation, 111SKIN's innovative Celestial Black Diamond Retinol Oil is a youth-boosting formula ideal for all skin types, including sensitive. Powered by a 2.5% retinol and granactive retinoid blend, suspended in a skin-soothing infusion of eight nourishing oils, the featherlight facial formula visibly transforms textural irregularities and uneven tone over time. Supported by diacetyl boldine to brighten and micro-fine black diamond powder to help absorb the actives optimally, the oil diminishes fine lines to encourage a smooth, supple and more sculpted appearance. Plus, its silky consistency sinks into the skin effortlessly, leaving no greasy residue before bed - just a hydrated glow upon awakening.
Black Diamond Retinol Oil is a rich oil from 111Skin. The formula is built mainly around hydration. The ingredient list runs to 28 ingredients, each broken down in full below.
By its ingredient list the formula reads as rich: occlusives and butters sit high enough in the order to give it real weight on skin. The oils in it point to a dewy, emollient finish rather than a matte one. Hydration is handled by Glycerin, Caprylic/capric Triglyceride and Isopropyl Myristate, humectants that pull water into the upper layers of skin rather than sealing it there.
Hydration: High. Ingredients that pull and hold water in the upper layers of skin, and here that comes from Glycerin, Caprylic/capric Triglyceride, Isopropyl Myristate and Squalane.
Cell renewal: Moderate. Retinoids, acids and enzymes that speed surface turnover, and here that comes from Hydroxypinacolone Retinoate, Retinol and Lactic Acid.
Brightening: Moderate. Ingredients that act on uneven tone and post-inflammatory marks, and here that comes from Hydroxypinacolone Retinoate, Tocopherol and Lactic Acid.
Soothing: Moderate. Ingredients aimed at visible redness and reactivity, and here that comes from Hydroxypinacolone Retinoate, Sodium Benzoate and Tocopherol.
On richness alone it suits Dry and Combination (dry) skin best, and is the least natural fit for Combination (oily) and Oily skin. Nothing in the list is flagged as a common irritant, which is a reasonable starting point for reactive skin — though a patch test is still the only way to know.
The formula contributes little or nothing on firmness signalling. That is not a fault — most products are not meant to do everything — but if one of those is your priority, this is not the product that will address it.
Reading the full list, the formula is essential-oil-free, no drying alcohol, paraben-free, silicone-free, microplastic-free and sulfate-free. Those claims come from the ingredient list itself, not from the packaging. It does contain fragrance, worth knowing if your skin reacts to any of them.
It can be used morning and evening. In a routine it goes after serums. Seal in your serums with it; in the morning, sunscreen still goes on top.
