OBAGI - Tretinoin GEL 0.05%

Prescription Only — Online Medical Assessment Required

Obagi Tretinoin Gel 0.05% is a prescription-strength retinoid gel formulation containing tretinoin — a clinically proven vitamin A derivative and the gold standard in topical skin renewal. The gel vehicle makes it particularly well suited to oily and acne-prone skin types, offering the same clinical efficacy as the cream formulation in a lighter, non-occlusive base.

Tretinoin works by accelerating skin cell turnover, stimulating collagen production, and clearing blocked pores — addressing acne, fine lines, uneven texture, and pigmentation at a cellular level.

What It Treats

• Acne and recurring blemishes — particularly suited to oily and acne-prone skin
• Fine lines and early signs of skin ageing
• Uneven skin tone and post-inflammatory hyperpigmentation
• Rough skin texture and enlarged pores
• Sun-damaged skin

Prescription-Only Formula

Obagi Tretinoin Gel 0.05% contains tretinoin, a prescription-only medicine in the UK. You’ll need to complete a free online consultation with our UK-based clinicians before purchase. This ensures the product is appropriate for your skin type and that you receive the correct usage guidance.

How to Use

Apply a small, pea-sized amount to clean, dry skin in the evening. Avoid the eye area, lips, and corners of the nose. The gel formulation absorbs quickly — allow it to dry fully before applying any additional products.

Always use a broad-spectrum SPF 30+ in the morning — tretinoin increases UV sensitivity and sun protection is essential throughout treatment.

Note: An adjustment period of 4–8 weeks is normal. Mild redness, flaking, or dryness during this phase does not indicate the product is unsuitable.

Frequently Asked Questions

What is tretinoin and how does it work?

Tretinoin is a prescription-strength retinoid — a derivative of vitamin A — that works by binding to receptors in skin cells and accelerating their natural renewal cycle. This helps clear blocked pores, reduce acne lesions, stimulate collagen production, and improve the appearance of fine lines, pigmentation, and uneven texture over time.

Why do I need a prescription for tretinoin?

Tretinoin is a prescription-only medicine in the UK. Our free online consultation connects you with UK-based clinicians who will assess your skin, confirm suitability, and provide personalised usage guidance before approving your order.

What is the difference between tretinoin gel and tretinoin cream?

The active ingredient — tretinoin — is identical in both formulations at the same concentration. The difference is the vehicle. Gel formulations are lighter, absorb more quickly, and are less occlusive, making them better suited to oily, combination, and acne-prone skin types. Cream formulations contain emollient agents that help offset the drying effects of tretinoin, making them more suitable for normal, dry, or sensitive skin. If you are unsure which is right for your skin, our team can advise.

What is the difference between 0.025%, 0.05%, and 0.1% tretinoin?

0.025% is the entry-level strength, typically recommended for first-time tretinoin users or those with sensitive skin. 0.05% is a mid-range concentration suitable for users who have built tolerance to lower strengths. 0.1% is the highest available concentration, reserved for experienced users under clinical guidance. Our team can advise which strength is appropriate for your skin.

What is the tretinoin purge and how long does it last?

The tretinoin purge is a temporary increase in breakouts or skin flaking that can occur during the first 4–8 weeks of treatment. It happens because tretinoin accelerates cell turnover, bringing congestion to the surface more quickly. It is a normal part of the adjustment process and typically resolves as the skin acclimatises to treatment.

How long does it take to see results?

Most users begin to notice improvements in skin texture and tone within 8–12 weeks of consistent use. Significant improvements in acne, fine lines, and pigmentation are typically visible at 3–6 months. Tretinoin is a long-term treatment — consistency is key.

Can I use tretinoin if I am pregnant or breastfeeding?

No — tretinoin is not suitable for use during pregnancy or breastfeeding. If you are pregnant, planning a pregnancy, or breastfeeding, please consult your doctor for alternative options.
