What is Retinal?
Retinal, a derivative of vitamin A, is a cornerstone in skincare, renowned for its ability to combat signs of aging and improve overall skin texture. It works by penetrating the skin to accelerate cell turnover, stimulate collagen production, and neutralize free radicals, leading to smoother, firmer, and more radiant skin.
What are the Benefits of Retinal?
Scientific research and dermatological studies have highlighted several key benefits of retinal:
- Reduces Fine Lines and Wrinkles: By boosting collagen and elastin production, retinal helps diminish the appearance of fine lines and wrinkles.
- Improves Skin Texture and Tone: Retinal enhances skin cell turnover, leading to a smoother texture, and more even tone. (If you’re planning to get a procedure like microneedling, using Retinal will help your skin turnover more quickly and with greater impact.)
- Fights Acne: Its exfoliating properties help unclog pores, reducing acne breakouts, and preventing future blemishes.
- Fades Hyperpigmentation: Regular use can lighten dark spots and post-acne marks, resulting in a more uniform complexion.

How to Use Medik8 Crystal Retinal: Building Tolerance the Right Way
Like any retinoid, Medik8 Crystal Retinal should be introduced gradually to avoid irritation, especially if you’re new to vitamin A products. Reddit users often emphasize the importance of going slow, even though Medik8 is known for being gentler than traditional retinal.
Step-by-Step: How to Build Up Tolerance
1. Start with a Low Strength
Begin with Crystal Retinal 1 or 3 if you’re new to retinoids or have sensitive skin. Medik8 offers a range of strengths (1, 3, 6, 10, and 20), so you can scale up over time.
2. Use the 2-2-2 Method
Many users recommend the “2-2-2” rule:
- Use 2 times a week for 2 weeks
- Then every other night for 2 weeks
- Then build up to nightly use if your skin tolerates it
3. Always Apply on Dry Skin
To minimize irritation, apply your retinal on completely dry skin after cleansing. Moist skin can increase absorption, which might cause stinging or peeling.
4. Follow with Moisturizer
Lock in hydration and reduce potential dryness by layering a gentle, non-comedogenic moisturizer on top.
5. Don’t Mix with Strong Actives
Avoid using exfoliating acids (AHAs, BHAs), vitamin C, or benzoyl peroxide in the same routine when starting out. Keep it simple.
Pro Tip: If you’re dealing with dryness or tightness, sandwich your retinol between two layers of moisturizer—a method known as the “moisture sandwich”—for extra comfort.
When to Increase Strength
Only consider moving up to a higher strength (e.g., from 3 to 6 or 6 to 10) once you can use your current level nightly with zero irritation for at least 4–6 weeks.
“I phased it in—2 nights a week for 2 weeks, then every other night until my skin could handle it. Now I use it nightly and love it.”

What Some Users Don’t Love About Medik8
While Medik8 Crystal Retinal has earned praise across Reddit skincare threads, not every experience is glowing. Like any active skincare product, it isn’t universally loved, and it’s important to share both sides.
Irritation & Purging
Some users with sensitive or acne-prone skin report experiencing breakouts or irritation. Upon reading this review, it appears that the user layered Retinal with AHA/BHA, which would be too strong and irritating.
“I’ve been using the Medik8 Crystal Retinal 3 for about 6 weeks and it has completely ruined my skin and self-confidence!”
— u/esstee123
High Cost vs. Results
While many swear by it, others feel the price doesn’t match the payoff—especially compared to more affordable retinal products.
“I much prefer G&G to Medik8! Felt pretty similar for a vastly lower price.”
— u/ollybee
No Results for Some
A few users shared that, despite consistent use, they didn’t notice any changes to their skin after several months.
“Crystal retinal 3 or 6 – zero effect after nine months of usage. Smells terrible.”
— u/[deleted]
Customer Service Concerns
In rare cases, users have mentioned poor customer service when trying to get product support or refunds.
“I contacted their customer service to say their ‘mild’ toner burned my skin. Nobody replied. I followed it up. Nobody replied.”
— u/[deleted]
Caution Around Eyes
While some users apply it near the eyes with no issue, others have experienced discomfort or are cautious due to risks like irritation or dry eye.
“Personally, I’d be really careful about using retinol under your eyes… I don’t find the risks worth it.”
— u/SalaciousBookWyrm
Summary
Retinal is one of the most promising ingredients in modern skincare, offering serious results with fewer side effects than traditional retinol. Whether you’re aiming to smooth fine lines, fade dark spots, or clear up breakouts, it’s a powerhouse worth considering.
Medik8 Crystal Retinal stands out in the Reddit skincare community for a reason—it delivers visible results, has a gentle yet effective formula, and offers a range of strengths for every stage of your skincare journey.

If you’re thinking of adding a retinal to your routine, Medik8 is a solid place to start. Just remember to introduce it slowly, stay consistent, and listen to your skin. Results take time—but with the right approach, they’re well within reach.
