CAROLINE SAYS

This is our strongest and most powerful retinoid, designed for advanced vitamin A users.

With high levels of retinoid to achieve a strong formula without compromising stability, this is a great serum if you’re already using high-strength formulas, or to power up results after an intermediate strength. This strong retinoid will significantly reduce the appearance of fine lines, wrinkles, breakouts, and hyperpigmentation for your brightest, smoothest, most radiant skin.

Key Ingredients

Retinal

A fast-acting, powerful retinoid that targets fine lines, wrinkles, breakouts, skin texture and hyperpigmentation.

Adapinoid®

Transforming to adapalene – a highly effective third generation retinoid for blemish-prone skin – once on the skin, this ingredient helps to reduce the appearance of breakouts while targeting signs of ageing such as fine lines, wrinkles and hyperpigmentation.

Bakuchiyl Salicylate

Breaking down to both bakuchiol and salicylic acid once on the skin, this compound helps to boost the efficacy of retinoids while decongesting the skin.

Soybean Extract

A retinoid booster that helps to bolster results while soothing and protecting the skin.

Squalane and Vitamin E

Conditioning agents that support the skin barrier while soothing and nourishing the skin.

FAQs

You’ve got questions,
We’ve got answers.

What active percentage of retinoid is in Retinoid 1/2/3?

Skin Rocks Retinoid 1 contains 0.2% hydroxypinacolone retinoate. Skin Rocks Retinoid 2 contains 0.5% hydroxypinacolone retinoate & 0.05% retinal, meaning that the product contains a total of 0.55% active retinoid. Skin Rocks Retinoid 3 contains 0.21% retinal, plus 0.5% adapinoid.

What’s the difference between Skin Rocks Retinoids 1, 2 and 3 and which one should I buy?

Retinoid 1 is our entry-level serum, Retinoid 2 is intermediate-strength, and Retinoid 3 is our strongest retinoid. Please refer to the individual product pages for details on ingredients.

Skin Rocks Retinoid 1 has been formulated for beginners or those with concerns around sensitivity. This includes those who have not used retinoids previously, or those who have used low-strength retinoids irregularly in the past. Retinoid 1 is suitable for those with sensitive skin, while Retinoids 2 and 3 are not.

Retinoid 2 is formulated for intermediate users, including those who have used low- or mid-strength retinoids without sensitivity and want to level up, and those who have previously used high-strength retinoids and want to maintain results.

People with advanced concerns may also start with Retinoid 2 for faster results, provided they are not sensitive and have completed a patch test.

Retinoid 3 is formulated for advanced users, including those who regularly use high-strength retinoids without sensitivity and wish to maintain results, and those using mid-strength retinoids without sensitivity who want to level up their results.

You should not use a retinoid if you have experienced previous vitamin A irritation. You should always patch test before using a new product.

How do I know when to move on to a higher-strength Retinoid?

Please wait at least 4 weeks for your skin to acclimatise to any product. We recommend using our Retinoid products for at least 12 weeks before moving on to a higher strength.

Can I use my refill without the pump?

No. It is essential to have the pump mechanism screwed onto the refill to dispense the product correctly, not waste any product, and protect the formula.

Can I use my refill interchangeably with either Retinoid bottle?

In theory, yes, but we advise you not to do this. For example, if you have purchased a Retinoid 1 and
want to purchase a Retinoid 2 Refill, we recommend not mixing the packaging to prevent cross-contamination of formulas.

Are there any shipping restrictions for Retinoids?

Yes, we cannot ship our Retinoids to Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and UAE. (Retinoid 3 is also not available to ship to Canada).
