Frequently Asked Questions

Is Crystal Retinal better than retinol?

Crystal Retinal features retinaldehyde, a next-generation form of vitamin A that works up to 11 times faster than retinol in the skin’s natural conversion to retinoic acid, which is the active form your skin uses. This means it can deliver visible results more quickly, including smoother texture, improved tone, and reduced fine lines.

Despite its potency, Crystal Retinal is formulated to be gentle and hydrating, making it suitable for even sensitive skin types.

Which Crystal Retinal strength should I start with?

If you're new to vitamin A or have sensitive skin, it's best to start with Crystal Retinal 1 or 3. These lower strengths are ideal for building tolerance while still delivering visible results. Once your skin adjusts, typically after one tube, you can step up gradually to higher strengths like Crystal Retinal 6 or 10 for enhanced benefits. For experienced vitamin A users or those with resilient skin, starting at Crystal Retinal 6 may be appropriate. Always introduce new strengths gradually, using them a few times a week at first, and follow with moisturiser and SPF. The tiered system is designed to support long-term, progressive results with minimal irritation.

Does Medik8 Crystal Retinal cause purging?

Unlike traditional retinoids, Medik8 Crystal Retinal is expertly formulated with skin-soothing and hydrating ingredients to minimise the risk of irritation or purging. Its encapsulated retinaldehyde works gradually within the skin, making it suitable even for sensitive skin types.

While some mild adjustments, like dryness or redness, can occur when introducing any vitamin A, Crystal Retinal’s gentle, stabilised formula is designed to deliver visible results without the typical retinoid side effects, including purging.

Medik8’s unique laddered strength system allows you to start at a lower level and gradually step up as your skin builds tolerance, helping ensure a smoother transition with minimal disruption.

Can I combine Crystal Retinal with other actives?

Yes, Crystal Retinal can be combined with other actives, but it’s important to do so thoughtfully to avoid overwhelming the skin. Medik8’s formulas are designed with compatibility in mind, so products like Press & Clear or Sleep Glycolic can be safely used in the same routine.

On nights you use Crystal Retinal, follow with a moisturiser that contains hydrating and barrier-supportive ingredients to help keep the skin calm and balanced. And as with all vitamin A products, be sure to apply a broad-spectrum SPF every morning.

Who can use Crystal Retinal products?

Crystal Retinal is suitable for most skin types and a wide range of users, from vitamin A beginners to experienced retinoid users. Its gentle yet effective formula makes it especially appealing for those looking to improve visible signs of ageing, refine skin texture, reduce the appearance of blemishes, or boost overall radiance, without the irritation often associated with traditional retinoids.

Thanks to Medik8’s laddered strength system, even sensitive skin types can start with a lower strength (like Crystal Retinal 1 or 3) and gradually build up as tolerance improves.

It’s not recommended during pregnancy or breastfeeding, but for most others, it offers a customisable, results-driven option for incorporating vitamin A into your routine.
