How should I layer SkinMedica TNS Advanced Serum and retinol in my routine?

A common routine is to use SkinMedica TNS Advanced Serum after cleansing and toning, allow it to absorb, and then apply a retinol product at night if your skin tolerates it. Many people use TNS Advanced Serum twice daily and introduce retinol slowly, starting a few nights per week. Moisturizer is usually applied after retinol, and daily broad-spectrum sunscreen is essential. If you are unsure about layering these products, speak with your skincare professional for personalized advice.

Can I use retinol and SkinMedica TNS Advanced Serum if I have sensitive skin?

If you have sensitive skin, you may still be able to use both SkinMedica TNS Advanced Serum and a gentle retinol, but it is important to introduce them carefully. Start with TNS Advanced Serum once or twice daily as directed, and add a low-strength or sensitive-skin retinol only a few nights per week. Monitor for redness, burning or excessive dryness and reduce frequency if needed. For sensitive, reactive or medically complex skin, consult with your dermatologist or skincare provider before combining active products.

Should I stop retinol if my skin becomes irritated while using TNS Advanced Serum?

If you notice irritation such as significant redness, burning, stinging or peeling after combining retinol with TNS Advanced Serum, it is usually best to pause retinol and allow your skin to recover. You can focus on a gentler routine with TNS Advanced Serum, moisturizer and sunscreen, then reintroduce retinol less frequently or in a milder formula if your provider agrees. If irritation persists, stop the products that seem to be causing it and seek advice from a qualified skincare professional.

Growth factors and retinol work in different but complementary ways. TNS focuses on cell signalling and collagen support, while retinol increases cell turnover and improves texture and fine lines. Many routines include TNS + a gentle retinol, introduced gradually to avoid irritation. Recommended Retinol product would be SkinMedica Retinol Strength 0.25.
